size-to-bytes

Tiny utility for converting human-friendly sizes (KB/MB/GB) into bytes.

Install

npm i size-to-bytes or pnpm add size-to-bytes or yarn add size-to-bytes

Usage

import { size } from "size-to-bytes";

const avatarLimit = size.MB(2);      // 2097152
const uploadLimit = size.MB(10);     // 10485760
const cacheCap = size.GB(1);         // 1073741824
const tinyThing = size.KB(256);      // 262144

API

size.KB(value: number): number

Returns value kilobytes in bytes (base-2 / kibibytes: 1 KB = 1024 bytes).

size.MB(value: number): number

Returns value megabytes in bytes (1 MB = 1024 KB).

size.GB(value: number): number

Returns value gigabytes in bytes (1 GB = 1024 MB).

Notes

Uses base-2 units (1024) which is typically what you want for file upload limits and memory sizes.

Input can be integers or decimals (size.MB(1.5) works).
