256-color palette · Client-side · No uploads

JPG in.
Retro GIF out.

GIF is a 1987 format with a hard limit of 256 colors. This tool converts any JPG into a single-frame GIF using a modern palette quantizer — right in your browser, no upload, no cloud.

The 256-color reality. JPG holds millions of colors. GIF holds just 256. Converting means picking the closest 256 shades — photos with smooth gradients (sunsets, skin, sky) will show visible banding. That's not a bug, it's the GIF spec. If you need photo fidelity, keep the JPG or use PNG.
How this tool works
01

Drop a JPG

Any .jpg or .jpeg up to 50 MB. Your browser shows it instantly — no decoding tricks needed.

02

We quantize to 256 colors

A median-cut algorithm finds the 256 best colors to represent your image, then maps every pixel to the nearest one.

03

Download the GIF

A single-frame GIF that works everywhere — old forums, chat apps, documents, email signatures.

Fewer colors = smaller file + a deliberate retro look. 256 is the GIF maximum. Anything below 64 gets a strong "80s pixel art" vibe.

What this tool does
  • Input: JPG or JPEG only. Other formats are politely rejected so you know you're in the right place.
  • Output: a single-frame GIF. Not an animation — one still image, 256 colors max.
  • Adjustable palette (2–256 colors). Fewer colors = smaller file, or a deliberate retro look.
  • Runs in Chrome, Firefox, Edge, Safari. Uses the HTML5 Canvas API + a WebAssembly-free JS encoder (gifenc).
  • Files stay on your device. No upload, no server, no tracking.
Your file never leaves your device

JPG decoding, palette quantization, and GIF encoding all run inside your browser. Open DevTools → Network and you'll see zero requests for the image itself.

Deep dive

How a 16-million-color photo becomes a 256-color GIF

Three steps happen under the hood. They take a few hundred milliseconds and run entirely on your device.

01

Decode JPG → pixels

The browser unpacks the JPG into raw RGBA values using its built-in JPEG decoder. This is the same step your screen already does — nothing extra happens here.

02

Quantize → 256 colors

A median-cut algorithm scans millions of pixels and picks the 256 colors that best represent the image. Every original pixel then snaps to the nearest chosen color. This is where banding comes from.

03

Encode → GIF bytes

Each pixel becomes a single byte (0–255) indexing into the palette. That byte stream is then LZW-compressed — a lossless scheme — and wrapped in the GIF file format.

When to use this

GIF still makes sense when…

You want a strong retro / lo-fi look

GIF's 256-color limit is a feature, not a bug. Drop the palette to 32 or 64 colors and you get an instant 80s pixel-art aesthetic.

You're targeting an old or constrained platform

Some industrial systems, embedded devices, and legacy CMSes only accept GIF. This gets you a compatible file in one click.

You're building a still frame for a GIF animation

If you're hand-building an animated GIF frame-by-frame, this is the fastest way to get a single-frame source to composite into your timeline.

You want the smallest possible file for flat graphics

For logos, icons, or illustrations with solid colors, GIF's LZW compression + small palette can beat PNG for size.

You need email-safe inline images

GIF has been supported in email clients since the 90s. When in doubt, GIF always works — even in Outlook.

You want to ship a tiny preview thumbnail

A heavily quantized GIF (16–32 colors) makes a great lightweight placeholder that loads instantly.

Common questions

Frequently asked

GIF can only hold 256 colors; your JPG probably had thousands or millions. The quantizer picks the 256 that best represent the image, but smooth gradients (sky, skin, sunsets) will show visible 'banding' — stripey transitions between similar shades. That's the format's hard limit, not a bug. If you need full color, use PNG instead.
