100% private — no upload
Some editors, print services and upload forms only accept PNG files. Drop your JPG photos below to convert them to PNG instantly — the conversion is lossless and runs entirely in your browser.
PNG, JPG, GIF, WebP, HEIC up to 50MB per file
Choose filesConverting JPEG to PNG does not improve the image. JPEG has already discarded information permanently, and PNG cannot bring it back — including any compression artefacts, which get preserved perfectly by a lossless format. The file will get considerably larger, often five to ten times, while looking exactly the same.
That is worth stating plainly because it is a common misunderstanding. PNG is not a higher-quality version of JPEG; it is a different trade-off. What it guarantees is that nothing further will be lost from this point onwards.
Editing is the main one. If you are going to open, modify and re-save an image several times, working in PNG stops each save from adding another round of JPEG loss. Convert once at the start, edit freely, and export back to JPEG or WebP at the end.
The other cases are practical: software or upload forms that only accept PNG, images you need to add transparency to, and screenshots containing text or interface elements where JPEG's block artefacts around sharp edges are visible and PNG's are not. Outside of those, keeping the JPEG is usually the better call.
No — PNG stores exactly the pixels decoded from your JPG, so existing JPEG artifacts remain. The benefit is that PNG won't add any further degradation, making it ideal before repeated editing.
PNG is lossless: it keeps every pixel exactly, which costs space. A 2MB JPG photo can become a 10MB PNG. That's normal — use PNG when a workflow requires it, not to save space.
When an app or form explicitly requires PNG, when you'll edit the image repeatedly (avoids cumulative JPEG loss), or when you need to add transparency in a later editing step.
Yes — drag all your JPG files at once (up to 50MB each). Everything converts in parallel in your browser and downloads as a single ZIP archive.
