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 into lossless PNG format instantly. Ideal for users who need transparency support or lossless editing workflows.
Both JPEG and PNG are raster image formats, but they handle data compression differently. JPEG uses lossy compression, which permanently discards image data to reduce file size, while PNG uses lossless compression. When you convert a JPEG to a PNG, you switch from lossy to lossless compression. However, keep in mind that the compression artifacts and lost data from the original JPEG cannot be recovered during this process.
Converting JPEG to PNG preserves the current visual quality without adding new compression artifacts, but it cannot restore details that were already lost when the original JPEG was saved.
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.
