JPG to PNG converter
Turn JPG photos into lossless PNG files — locally, no upload.
Convert JPG to PNG in your browser
JPG is a compact, lossy format built for photographs, but it cannot store transparency and it re-compresses the image every time you save. Converting a JPG to PNG gives you a lossless copy: PNG keeps every pixel exactly as it is, which is what you want before editing, cutting out a background, or placing an image into a logo, diagram or screenshot. From that point on, repeated saves no longer degrade the picture.
Because the conversion runs locally in your browser, it is instant and completely private — the JPG is read, decoded and re-encoded as PNG on your own device, with nothing uploaded to a server. There is no file-size limit beyond what your browser can hold in memory, and no waiting in a queue.
Keep in mind that a PNG is usually larger than the same photo as JPG, because lossless compression cannot discard detail the way JPG does. Convert to PNG when you need editing headroom or transparency; if you only need a smaller file to share, the compressor or a WebP export is the better choice.
Frequently asked questions
No — it cannot recover detail that JPG already discarded. What it does is stop further loss: the PNG is a lossless copy, so future edits and saves keep full quality.
For photographs, usually yes, because PNG stores every pixel without lossy compression. For flat graphics, logos or screenshots the difference is small.
Converting alone does not remove a background, but PNG supports transparency — so you can then erase or cut out areas in an editor and keep them transparent.
No. The file is decoded and re-encoded entirely in your browser. You can disconnect from the internet after the page loads and the converter still works.
