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 AVIF raster images to JPEG format instantly using ConvertX. This tool is essential when older software or platforms reject modern AVIF files.
AVIF and JPEG are both raster image formats, but AVIF utilizes advanced compression algorithms often yielding smaller files at high visual fidelity. When you convert AVIF to JPEG, the image data is re-encoded into the JPEG standard. Because both formats utilize lossy compression architectures, this transcode process involves secondary compression which can subtly impact edge sharpness and detail.
Since both formats use lossy compression, converting AVIF to JPEG means double-compressing the raster data, which can introduce minor quality degradation.
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.
