HEIC to GIF Converter

About HEIC to GIF

Decodes a HEIC photo in the browser and then saves it as a genuine GIF, the 256-color format. Realistically this is a niche conversion, needed when an old system will accept a GIF and nothing else; photographs lose smooth tones when limited to a palette.

How to use it

1. Drop a .heic or .heif file onto the dropzone, or click to select it.
2. Give the preview a moment, since the photo has to be decoded before it can display.
3. Click Convert to GIF. No adjustments are offered.
4. Save the file with Download GIF once the Output section appears.

When to use it

• Satisfying a legacy portal that lists GIF as the only image type for uploads.
• Creating a stylized, reduced-color version of a phone photo.
• Producing a still that another program will animate.

Questions about HEIC to GIF

Will my iPhone photo look good as a GIF?

Rarely. A phone picture has millions of colors and GIF allows 256 per frame, so gradients show banding. For a broadly compatible photo, HEIC to JPG is the better choice.

What steps happen in the background?

The HEIC is first decoded to a PNG-quality image by a WebAssembly decoder, drawn onto a canvas at its full pixel size, and only then written as a GIF by the tool's own encoder, which picks a 256-color palette.

Is the output truly GIF data?

Yes. Browsers cannot encode GIF from a canvas and return PNG instead, so the tool writes a real GIF89a file itself, with LZW-compressed pixels that strict receiving systems accept.

Does the file get resized?

No. The canvas uses the decoded photo's exact width and height, so a 12 megapixel photo stays 12 megapixels. Resize before or after if you need something smaller.
