Why people convert JPG to PNG

Every time a JPG is edited and saved again, it is compressed again and loses a little more detail. PNG is lossless: once your picture is a PNG, you can crop, annotate and re-save it as often as you like without it getting worse. That makes PNG the safer working format for editing, for design tools that expect PNG layers, and for websites or apps that only accept PNG uploads.

What this converter does — and what it cannot do

It keeps every pixel. The PNG has exactly the same width, height and appearance as your JPG.
It does not restore lost quality. Blockiness or blur already present in the JPG stays in the PNG. Converting stops further loss; it cannot undo earlier loss.
It does not remove the background. The PNG supports transparency, but your image stays fully opaque. To cut out the subject, use Remove Background.
The file gets bigger. Lossless storage of a photo usually produces a file several times larger than the JPG. That is normal.
Camera details are removed. EXIF data such as camera model and GPS location is not carried over, which is useful before sharing a photo publicly.

A typical workflow

Convert the original JPG to PNG here.
Do your edits, annotations or design work on the PNG.
When the final version needs to be small again, convert it back with PNG to JPG or shrink it with Compress Image.

This way the picture is compressed only once, at the very end, instead of after every edit.

Questions about JPG to PNG

Why is my PNG so much larger than the JPG?

JPG throws away detail to save space; PNG keeps everything. A larger PNG is the expected result, not an error.

Can I convert several photos together?

Yes. Select multiple JPG files and each one gets its own PNG download.

Is anything uploaded?

No. Conversion happens inside your browser and the files stay on your device.
