About the JPG to PNG Converter

The JPG to PNG Converter converts JPG images to lossless PNG, useful when you need to edit further without adding compression artefacts. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Preparing an image for further editing.
  • Meeting a requirement that only accepts PNG.
  • Avoiding extra generation loss on a re-save.
Converting JPG to PNG cannot recover detail already lost to JPG compression, and the file will usually get larger. It stops further loss; it does not undo past loss.

Frequently asked questions

Is the JPG to PNG Converter free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is what I paste into the JPG to PNG Converter stored?
No. The JPG to PNG Converter runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the JPG to PNG Converter used for?
The jobs it is built for: preparing an image for further editing. Meeting a requirement that only accepts PNG. Avoiding extra generation loss on a re-save. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
Converting JPG to PNG cannot recover detail already lost to JPG compression, and the file will usually get larger. It stops further loss; it does not undo past loss.
Is there a file size limit?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
