Convert JPG to PNGRight in Your Browser

Converting JPG to PNG is what you do before editing an image or feeding it into a tool that requires a lossless source. PNG won't recover detail that JPEG compression already discarded — nothing can — but it stops the bleeding: from that point on, edits and re-saves are mathematically lossless, so the tenth save looks exactly like the first.

That's the real reason editors and print workflows ask for PNG. Every time a JPG is opened, modified and saved as JPG again, the encoder re-compresses the whole image and artifacts accumulate — the digital equivalent of photocopying a photocopy. Converting to PNG first means only the original JPEG compression is ever baked in.

PNG is also the answer when you need an alpha channel. JPG has no concept of transparency, so tools that cut out backgrounds, overlay watermarks or compose layers need PNG (or WEBP) to hold the result. And some systems are simply strict about input: print-on-demand services, app-icon pipelines and OCR tools frequently require PNG regardless of content.

Don't convert just to "improve" a photo, though — a PNG made from a JPG is a faithful copy of the compressed image, several times larger on disk. If the file is only being viewed or shared, leaving it as JPG costs nothing and saves space. The conversion here runs on your device with the browser's own codecs: instant, free and private.
