Convert JPG to lossless PNG in your browser
Some software, print services, and upload forms insist on PNG. Others need it because PNG survives repeated editing without degrading. Whatever the reason, this tool converts JPG (and JPEG) files to PNG entirely on your device — private, instant, and free.
Batch-convert as many files as you like; there are no limits because there's no server doing the work.

Frequently asked questions
Are my images uploaded anywhere?
No. The conversion runs locally in your browser — your images never leave your device.
Why convert JPG to PNG?
PNG is lossless, so it's the right format when you plan to edit an image repeatedly, need it for software that requires PNG, or want to avoid further quality loss from re-saving as JPG.
Will this improve the quality of my JPG?
No — quality lost to JPG compression is gone permanently. Converting to PNG preserves the image exactly as it is now and prevents any further loss.
Why is the PNG file bigger than my JPG?
PNG stores every pixel losslessly while JPG uses aggressive compression, so PNGs of photos are typically 5–10× larger. That's expected.
