JPG to PNG Converter
Convert JPG and JPEG photos to PNG locally, with drag-and-drop, batch support and a ZIP download when you have several. PNG is lossless, which helps when you need transparency or crisp edges — just know it can't rebuild detail already lost to JPG compression, and the files usually come out larger.

Frequently asked questions
Will converting to PNG improve quality?
No. PNG is lossless, but it can only preserve what is already in the JPG — it cannot recover detail lost to earlier JPG compression.
Why is my PNG bigger than the JPG?
PNG stores images losslessly, so photographic content is usually much larger than the equivalent lossy JPG.
Are my images uploaded?
No. Conversion happens entirely in your browser; files never leave your device.
