What is a JPG to PNG?
Converting JPG to PNG is common when a downstream tool requires PNG input, when you need to add transparency to an image that started as JPG (by editing it after conversion), or when you want to stop lossy re-compression from degrading a file further as it passes through multiple edits and re-saves.
The conversion itself is lossless — PNG re-encodes the exact pixels the JPG decoded to, without additional quality loss. It does not undo compression artefacts already present in the source JPG; those pixels are baked in and will carry over exactly as they appear in the original.
How to use it
- Drop a JPG file onto the panel, or click to browse.
- The converted PNG preview appears automatically — no quality setting needed, since PNG is lossless.
- Click Download PNG to save the result.

Will converting to PNG remove JPG compression artefacts?
No. Whatever blockiness or blurring was already in the JPG is part of the pixel data and carries over exactly. PNG conversion prevents further quality loss going forward; it cannot recover detail the JPG's original compression already discarded.
Why would I want a larger PNG instead of a smaller JPG?
PNG is often required by tools that need lossless input (further image editing, certain print workflows) or transparency support that JPG cannot provide. If file size is the priority and the image is a photograph, keeping it as JPG is usually the better choice.
Is my image uploaded anywhere?
No. The conversion happens entirely in your browser using the HTML Canvas API. The file never leaves your device.
