Convert a JPG to PNG when you need a lossless copy for editing, or a format that some tools and print workflows prefer.
Convert between JPG, PNG and WebP — multiple files at once
🔒 100% private — files are processed in your browser and never uploaded to any server.
No — it prevents further loss but cannot restore what JPG compression already removed. Use it to stop quality dropping during repeated edits.
PNG stores every pixel exactly, so photographic images are bigger than their lossy JPG version. That is expected.
No software and no sign-up. The JPG-to-PNG converter runs in your web browser, so it works on any device — Windows, Mac, Android or iPhone — straight from this page.
Yes. Drop in several images and they are converted together; a single file downloads directly, while a batch arrives as a ZIP.
No. Conversion happens entirely in your browser — your images never leave your device.

JPG — JPEG. JPEG is the universal photo format — nearly 30 years old and readable by every device, browser and app on earth. It uses lossy compression that is superb for photographs, keeping files small while looking clean, which is why cameras and phones default to it. Its weaknesses are that it cannot store transparency and it adds visible halos around sharp text and hard edges, so it is a poor choice for logos, screenshots and line art.
PNG — PNG. PNG is a lossless format, meaning it reproduces every pixel exactly with no compression artefacts. That makes it the right choice for screenshots, logos, icons, diagrams and anything with crisp edges or flat colour, and it fully supports transparency. The trade-off is size: a photograph saved as PNG can be several times larger than the same image as JPG, so PNG is not suited to camera photos you need to keep small.
PNG is lossless but larger, and it cannot recover detail a JPG already discarded — the PNG will look like the JPG, just without further loss from here on.
Drop in as many JPG files as you need and they are converted together, arriving as a single ZIP. Because the work happens on your own device rather than on a server, a batch is limited only by your own memory, and there is no queue, no daily cap and no sign-up. Private or sensitive images stay entirely with you.
Need a different conversion, or want to process a batch? The full image converter handles JPG, PNG and WebP together, and you can pair it with the compressor if the result also needs to hit a size limit.
The same JPG reader feeds each conversion below, so whichever output you pick the file is still decoded on your own device.
If what you are starting from is not a JPG, open the converter that matches your own file instead.
