Why can't I load a .heic file directly?

Most browsers do not natively decode the HEIC codec (HEVC/H.265). If your browser blocks it, rename the file to .jpg — iOS actually stores HEIC-compatible JPEG data in many exports — or use the macOS/Windows conversion tips shown below the tool.

Is my photo uploaded to any server?

No. All processing uses the browser Canvas API and the open-source gif.js library. Your image bytes never leave your device.

Why does GIF look less sharp than the original?

GIF supports only 256 colors per frame. Photos with gradients and many colors will look posterized. GIF is best for illustrations, diagrams, and simple graphics rather than full-color photography.

How do I convert a true HEIC file on Windows?

Install the "HEIF Image Extensions" from the Microsoft Store, then open the HEIC in Photos and use File > Save a copy as JPEG. You can then upload the JPEG here to get a GIF.

How do I convert HEIC to GIF on a Mac?

Open the HEIC in Preview, choose File > Export, and select GIF or JPEG from the format dropdown. macOS has built-in HEIC support via Core Image.

What is the maximum file size this tool handles?

There is no hard server-side limit because processing is local. Very large images (over 12 MP) may be slow in-browser. Use the resize option to cap the output width for faster encoding.

On Windows Install HEIF Image Extensions (free, Microsoft Store) → open in Photos → File → Save a copy as JPEG → upload here.

Summary

Upload a HEIC (or JPEG/PNG) photo and download it as a GIF image — entirely in your browser, no upload to any server.

How it works

Click "Choose File" and select a HEIC, JPEG, or PNG image from your device.
The browser decodes the image and renders it on a canvas element.
Optionally resize the output by setting a maximum width.
Click "Convert to GIF" — the gif.js library encodes the canvas frame as a GIF.
A preview appears and a "Download GIF" button lets you save the result.

Use cases

Share an iPhone photo in GIF format with apps or services that do not support HEIC.
Embed a product photo on a website that requires GIF format.
Convert a screenshot taken on iOS to a universally readable image format.
Quickly produce a low-color GIF thumbnail from a high-resolution HEIC shot.
