JPG to PNG converter

Questions people ask

Will converting to PNG improve my photo?

No — the detail a JPG discarded when it was first saved is gone for good, and PNG cannot bring it back. What PNG does is stop any further loss, which matters if you plan to edit and re-save the image repeatedly.

Why is the PNG larger than the original JPG?

That is expected. PNG stores the image losslessly, so a photograph often becomes several times bigger. Convert to PNG when you need lossless editing, not when you need a smaller file.

Are my images uploaded anywhere?

No. The conversion runs in your browser using the Canvas API, and this site has no upload endpoint. Once the page has loaded you can go offline and it still works.

Is there a file size or batch limit?

You can convert 25 images at a time, and file size is limited only by your device's memory. Because there is no server involved, there is no daily cap and no account to create.

Does converting reduce the image quality?

Converting to PNG is lossless. Converting to JPG or WebP re-compresses the picture, so the quality slider controls the trade-off — 82% is a good default that most people cannot distinguish from the original.
