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.
Instantly convert JPG files to JPEG format using ConvertX. This tool helps meet strict system requirements where a specific four-letter file extension is mandatory.
Both JPG and JPEG are fundamentally the same raster image format, rooted in the JPEG standard. Because both formats utilize lossy compression, converting a JPG to a JPEG simply involves reading the raster pixel data and saving it with a .jpeg extension. The underlying compression algorithm remains identical, meaning no structural transformation of the image data occurs unless explicitly re-encoded.
Image quality generally remains unchanged during this conversion. However, since both formats involve lossy compression, avoid repeated re-saving to prevent cumulative generation loss.
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.
