This is Zod's biggest release since 4.0. It addresses several of Zod's longest-standing feature requests.

z.fromJSONSchema()

Convert JSON Schema to Zod (#​5534, #​5586)

You can now convert JSON Schema definitions directly into Zod schemas. This function supports JSON Schema "draft-2020-12", "draft-7", "draft-4", and OpenAPI 3.0.

import * as z from "zod";

const schema = z.fromJSONSchema({
  type: "object",
  properties: {
    name: { type: "string", minLength: 1 },
    age: { type: "integer", minimum: 0 },
  },
  required: ["name"],
});

schema.parse({ name: "Alice", age: 30 }); // ✅

The API should be considered experimental. There are no guarantees of 1:1 "round-trip soundness": MySchema > z.toJSONSchema() > z.fromJSONSchema(). There are several features of Zod that don't exist in JSON Schema and vice versa, which makes this virtually impossible.

Features supported:

• All primitive types (string, number, integer, boolean, null, object, array)
• String formats (email, uri, uuid, date-time, date, time, ipv4, ipv6, and more)
• Composition (anyOf, oneOf, allOf)
• Object constraints (additionalProperties, patternProperties, propertyNames)
• Array constraints (prefixItems, items, minItems, maxItems)
• $ref for local references and circular schemas
• Custom metadata is preserved

z.xor() — exclusive union (#​5534)

A new exclusive union type that requires exactly one option to match. Unlike z.union() which passes if any option matches, z.xor() fails if zero or more than one option matches.

const schema = z.xor([z.string(), z.number()]);

schema.parse("hello"); // ✅
schema.parse(42);      // ✅
schema.parse(true);    // ❌ zero matches

When converted to JSON Schema, z.xor() produces oneOf instead of anyOf.

z.looseRecord() — partial record validation (#​5534)

A new record variant that only validates keys matching the key schema, passing through non-matching keys unchanged. This is used to represent patternProperties in JSON Schema.

const schema = z.looseRecord(z.string().regex(/^S_/), z.string());

schema.parse({ S_name: "John", other: 123 });
// ✅ { S_name: "John", other: 123 }
// only S_name is validated, "other" passes through

.exactOptional() — strict optional properties (#​5589)

A new wrapper that makes a property key-optional (can be omitted) but does not accept undefined as an explicit value.

const schema = z.object({
  a: z.string().optional(),      // accepts `undefined`
  b: z.string().exactOptional(), // does not accept `undefined`
});

schema.parse({});                  // ✅
schema.parse({ a: undefined });    // ✅
schema.parse({ b: undefined });    // ❌

This makes it possible to accurately represent the full spectrum of optionality expressible using exactOptionalPropertyTypes.

.apply()

A utility method for applying arbitrary transformations to a schema, enabling cleaner schema composition. (#​5463)

const setCommonChecks = <T extends z.ZodNumber>(schema: T) => {
  return schema.min(0).max(100);
};

const schema = z.number().apply(setCommonChecks).nullable();

.brand() cardinality

The .brand() method now accepts a second argument to control whether the brand applies to input, output, or both. Closes #​4764, #​4836.

// output only (default)
z.string().brand<"UserId">();           // output is branded (default)
z.string().brand<"UserId", "out">();    // output is branded
z.string().brand<"UserId", "in">();     // input is branded
z.string().brand<"UserId", "inout">();  // both are branded

Type predicates on .refine() (#​5575)

The .refine() method now supports type predicates to narrow the output type:

const schema = z.string().refine((s): s is "a" => s === "a");

type Input = z.input<typeof schema>;   // string
type Output = z.output<typeof schema>; // "a"

ZodMap methods: min, max, nonempty, size (#​5316)

ZodMap now has parity with ZodSet and ZodArray:

const schema = z.map(z.string(), z.number())
  .min(1)
  .max(10)
  .nonempty();

schema.size; // access the size constraint

.with() alias for .check() (359c0db)

A new .with() method has been added as a more readable alias for .check(). Over time, more APIs have been added that don't qualify as "checks". The new method provides a readable alternative that doesn't muddy semantics.

z.string().with(
  z.minLength(5),
  z.toLowerCase()
);

// equivalent to:
z.string().check(
  z.minLength(5),
  z.trim(),
  z.toLowerCase()
);

z.slugify() transform

Transform strings into URL-friendly slugs. Works great with .with():

// Zod
z.string().slugify().parse("Hello World");           // "hello-world"

// Zod Mini
// using .with() for explicit check composition
z.string().with(z.slugify()).parse("Hello World");   // "hello-world"

z.meta() and z.describe() in Zod Mini (947b4eb)

Zod Mini now exports z.meta() and z.describe() as top-level functions for adding metadata to schemas:

import * as z from "zod/mini";

// add description
const schema = z.string().with(
  z.describe("A user's name"),
);

// add arbitrary metadata
const schema2 = z.number().with(
  z.meta({ deprecated: true })
);

New locales

• Armenian (am) (#​5531)
• Uzbek (uz) (#​5519)

import * as z from "zod";
import { uz } from "zod/locales";

z.config(uz());

Bug fixes

All of these changes fix soundness issues in Zod. As with any bug fix there's some chance of breakage if you were intentionally or unintentionally relying on this unsound behavior.

⚠️ .pick() and .omit() disallowed on object schemas containing refinements (#​5317)

Using .pick() or .omit() on object schemas with refinements now throws an error. Previously, this would silently drop the refinements, leading to unexpected behavior.

const schema = z.object({
  password: z.string(),
  confirmPassword: z.string(),
}).refine(data => data.password === data.confirmPassword);

schema.pick({ password: true });
// 4.2: refinement silently dropped ⚠️
// 4.3: throws error ❌

Migration: The easiest way to migrate is to create a new schema using the shape of the old one.

const newSchema = z.object(schema.shape).pick({ ... })

⚠️ .extend() disallowed on refined schemas (#​5317)

Similarly, .extend() now throws on schemas with refinements. Use .safeExtend() if you need to extend refined schemas.

const schema = z.object({ a: z.string() }).refine(/* ... */);

// 4.2: refinement silently dropped ⚠️
// 4.3: throws error ✅
schema.extend({ b: z.number() });
// error: object schemas containing refinements cannot be extended. use `.safeExtend()` instead.

⚠️ Stricter object masking methods (#​5581)

Object masking methods (.pick(), .omit()) now validate that the keys provided actually exist in the schema:

const schema = z.object({ a: z.string() });

// 4.3: throws error for unrecognized keys
schema.pick({ nonexistent: true });
// error: unrecognized key: "nonexistent"

v4.1.0

Compare Source

The first minor version since the introduction of Zod 4 back in May. This version contains a number of features that barely missed the cut for the 4.0 release. With Zod 4 stable and widely adopted, there's more time to resume feature development.

Codecs

This is the flagship feature of this release. Codecs are a new API & schema type that encapsulates a bi-directional transformation. It's a huge missing piece in Zod that's finally filled, and it unlocks some totally new ways to use Zod.

const stringToDate = z.codec(
  z.iso.datetime(),  // input schema: ISO date string
  z.date(),          // output schema: Date object
  {
    decode: (isoString) => new Date(isoString), 
    encode: (date) => date.toISOString(),
  }
);

New top-level functions are added for processing inputs in the forward direction ("decoding") and backward direction ("encoding").

stringToDate.decode("2025-08-21T20:59:45.500Z")
// => Date

stringToDate.encode(new Date())
// => "2025-08-21T20:59:45.500Z"

Note — For bundle size reasons, these new methods have not added to Zod Mini schemas. Instead, this functionality is available via equivalent top-level functions.

// equivalent at runtime
z.decode(stringToDate, "2024-01-15T10:30:00.000Z");
z.encode(stringToDate, new Date());

.parse() vs .decode()

Both .parse() and decode() process data in the "forward" direction. They behave identically at runtime.

stringToDate.parse("2025-08-21T20:59:45.500Z");
stringToDate.decode("2025-08-21T20:59:45.500Z");

There is an important difference however. While .parse() accepts any input, .decode() expects a strongly typed input. That is, it expects an input of type string, whereas .parse() accepts unknown.

stringToDate.parse(Symbol('not-a-string'));
// => fails at runtime, but no TypeScript error

stringToDate.decode(Symbol("not-a-string"));
//                     ^ ❌ Argument of type 'symbol' is not assignable to parameter of type 'Date'. ts(2345)

This is a highly requested feature unto itself:

• #​3860
• #​1748
• #​3978
• #​1892

Encoding

You can use any Zod schema with .encode(). The vast majority of Zod schemas are non-transforming (the input and output types are identical) so .decode() and .encode() behave identically. Only certain schema types change their behavior:

• Codecs — runs from B->A and executes the encode transform during encoding
• Pipes — these execute B->A instead of A->B
• Defaults and prefaults — Only applied in the forward direction
• Catch — Only applied in the forward direction

Note — To avoid increasing bundle size unnecessarily, these new methods are not available on Zod Mini schemas. For those schemas, equivalent top-level functions are provided.

The usual async and safe variants exist as well:

// decode methods
stringToDate.decode("2024-01-15T10:30:00.000Z")
await stringToDate.decodeAsync("2024-01-15T10:30:00.000Z")
stringToDate.safeDecode("2024-01-15T10:30:00.000Z")
await stringToDate.safeDecodeAsync("2024-01-15T10:30:00.000Z")

// encode methods
stringToDate.encode(new Date())
await stringToDate.encodeAsync(new Date())
stringToDate.safeEncode(new Date())
await stringToDate.safeEncodeAsync(new Date())

Example codecs

Below are some "worked examples" for some commonly-needed codecs. These examples are all tested internally for correctness. Just copy/paste them into your project as needed. There is a more comprehensive set available at zod.dev/codecs.

stringToBigInt

Converts bigint into a serializable form.

const stringToBigInt = z.codec(z.string(), z.bigint(), {
  decode: (str) => BigInt(str),
  encode: (bigint) => bigint.toString(),
});

stringToBigInt.decode("12345");  // => 12345n
stringToBigInt.encode(12345n);   // => "12345"

json

Parses/stringifies JSON data.

const jsonCodec = z.codec(z.string(), z.json(), {
  decode: (jsonString, ctx) => {
    try {
      return JSON.parse(jsonString);
    } catch (err: any) {
      ctx.issues.push({
        code: "invalid_format",
        format: "json_string",
        input: jsonString,
        message: err.message,
      });
      return z.NEVER;
    }
  },
  encode: (value) => JSON.stringify(value),
});

To further validate the data, .pipe() the result of this codec into another schema.

const Params = z.object({ name: z.string(), age: z.number() });
const JsonToParams = jsonCodec.pipe(Params);

JsonToParams.decode('{"name":"Alice","age":30}');  // => { name: "Alice", age: 30 }
JsonToParams.encode({ name: "Bob", age: 25 });     // => '{"name":"Bob","age":25}'

Further reading

For more examples and a technical breakdown of how encoding works, reads theannouncement blog post and new Codecs docs page. The docs page contains implementations for several other commonly-needed codecs:

• stringToNumber
• stringToInt
• stringToBigInt
• numberToBigInt
• isoDatetimeToDate
• epochSecondsToDate
• epochMillisToDate
• jsonCodec
• utf8ToBytes
• bytesToUtf8
• base64ToBytes
• base64urlToBytes
• hexToBytes
• stringToURL
• stringToHttpURL
• uriComponent
• stringToBoolean

.safeExtend()

The existing way to add additional fields to an object is to use .extend().

const A = z.object({ a: z.string() })
const B = A.extend({ b: z.string() })

Unfortunately this is a bit of a misnomer, as it allows you to overwrite existing fields. This means the result of .extend() may not literally extend the original type (in the TypeScript sense).

const A = z.object({ a: z.string() }) // { a: string }
const B = A.extend({ a: z.number() }) // { a: number }

To enforce true extends logic, Zod 4.1 introduces a new .safeExtend() method. This statically enforces that the newly added properties conform to the existing ones.

z.object({ a: z.string() }).safeExtend({ a: z.number().min(5) }); // ✅
z.object({ a: z.string() }).safeExtend({ a: z.any() }); // ✅
z.object({ a: z.string() }).safeExtend({ a: z.number() });
//                                       ^  ❌ ZodNumber is not assignable 

Importantly, this new API allows you to safely extend objects containing refinements.

const AB = z.object({ a: z.string(), b: z.string() }).refine(val => val.a === val.b);
const ABC = AB.safeExtend({ c: z.string() });
// ABC includes the refinements defined on AB

Previously (in Zod 4.x) any refinements attached to the base schema were dropped in the extended result. This was too unexpected. It now throws an error. (Zod 3 did not support extension of refined objects either.)

z.hash()

A new top-level string format for validating hashes produced using various common algorithms & encodings.

const md5Schema = z.hash("md5");          
// => ZodCustomStringFormat<"md5_hex">

const sha256Base64 = z.hash("sha256", { enc: "base64" }); 
// => ZodCustomStringFormat<"sha256_base64">

The following hash algorithms and encodings are supported. Each cell provides information about the expected number of characters/padding.

z.hex()

To validate hexadecimal strings of any length.

const hexSchema = z.hex();

hexSchema.parse("123abc");    // ✅ "123abc"
hexSchema.parse("DEADBEEF");  // ✅ "DEADBEEF" 
hexSchema.parse("xyz");       // ❌ ZodError

Additional changes

1. z.uuid() now supports the "Max UUID" (FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF) per the RFC
2. $ZodFunction is now a subtype of $ZodType
