What is JPG to GIF Converter?

JPG to GIF converts JPEG photos into the GIF format. GIF uses a palette of up to 256 colours with lossless LZW compression, which suits flat-colour images and simple graphics. For detailed photographs, the colour reduction is visible, but the file becomes a standard GIF that any tool can open.

This converter decodes your JPG with the browser's image engine, reduces the colours to a 256-entry palette using median-cut quantization, then builds a standard GIF89a file. Nothing is uploaded to a server.

How to Use JPG to GIF Converter

1

Drop a JPG file onto the upload area or click to browse

2

Wait a moment while the image is decoded and quantized

3

Preview the GIF result next to your original

4

Click Download to save the GIF

Common Use Cases

  • Turning a simple JPG graphic into a web-friendly GIF.
  • Converting a JPG to GIF for tools that require the GIF format.
  • Creating a single-frame GIF from a JPEG image.
  • Reducing a flat-colour JPG to a compact 256-colour GIF.

Example Input and Output

A flat-colour JPG converts to a compact 256-colour GIF.

Input
banner.jpg (140 KB, JPEG)
Output
banner.gif (60 KB, 256-colour GIF)

How This Tool Works

The browser decodes the JPG to canvas pixels, median-cut quantization builds a ≤256-colour palette, the pixel indices are LZW-compressed, and a GIF89a file is assembled for download.

Colour reduction

Median-cut quantization builds a representative 256-colour palette. Images with fewer than 256 colours convert losslessly.

Privacy

The converter never sends your image to a server — everything happens in your browser tab.

Frequently Asked Questions

Is my JPG uploaded anywhere?

No. Decoding, colour quantization, and GIF encoding all run locally in your browser.

Why does the GIF look different?

GIF supports at most 256 colours, so detailed JPEG photos are reduced to a 256-colour palette. Flat-colour images convert with little visible change.

Will the GIF be animated?

No. The converter produces a single-frame GIF from the JPEG.

What image sizes are supported?

Any size your browser can decode. Larger images take longer because quantization runs per pixel.
