Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert HEIC raster images to GIF raster format instantly using ConvertX. This tool is essential when you need to transform Apple photos into widely compatible animated or static images for older web systems.
Both HEIC and GIF are raster image formats, but they serve fundamentally different purposes. HEIC utilizes advanced compression to keep file sizes small on Apple devices, while GIF is a legacy raster format limited to 256 colors per frame, famously used for simple web loops and animations. When you convert HEIC to GIF, the image data goes from a modern lossy format into GIF's restricted color palette. Because GIF encodes pixels differently and often duplicates animation frames or color tables, the resulting file usually becomes significantly larger than the original HEIC.
Since HEIC is a format with losses, the original detail lost during Apple's initial photo compression cannot be restored. Furthermore, converting to GIF introduces additional quantization losses due to the 256-color limit.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
