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 JPEG raster images to JPG format instantly with ConvertX. This tool is essential when specific upload systems require the exact .jpg file extension.
Both JPEG and JPG are fundamentally the same raster image format, differing only in the historical three-letter file extension limit of early Windows systems. Because both formats use lossy compression algorithms, converting between them involves decoding and re-encoding the pixel data. This process means that repeatedly saving the file can introduce generational loss, although a single conversion keeps changes to a minimum.
Since both formats use lossy compression, re-encoding can slightly degrade image quality, though file size typically changes only negligibly.
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.
