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 your JPEG raster images to GIF raster format instantly. This tool is essential for web designers and developers needing to prepare graphics for specific legacy platforms or simple color palettes.
Both JPEG and GIF are raster image formats, but their underlying architectures are fundamentally different. JPEG uses lossy compression optimized for continuous-tone photographs with millions of colors, whereas GIF uses lossless compression limited to a maximum palette of 256 indexed colors. When you convert a JPEG to a GIF, the image is forced into this restricted 8-bit color space, requiring color quantization that often introduces noticeable banding or dithering.
Because you are converting from a lossy format (JPEG) to a lossless format (GIF), any compression artifacts from the original JPEG are permanently baked in, and the lost detail cannot be recovered. Furthermore, the file size will usually become larger due to the inefficient handling of continuous photographic tones within GIF's 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.
