Convert JPG to PNG
Some tools, printers and marketplaces only accept PNG — and PNG is the safer format to edit repeatedly, because saving it again never degrades the image the way re-saving a JPG does.

About JPG (JPEG)
JPG uses lossy compression tuned for photographs — smooth gradients and natural detail compress extremely well, so files stay small. It has no transparency, and hard-edged graphics or text can show compression artefacts.
About PNG (Portable Network Graphics)
PNG is a lossless format: every pixel is preserved exactly, and it supports full alpha transparency. That makes it the default for screenshots, logos, UI graphics and cut-outs — at the cost of larger files than JPG or WebP for photographs.
Frequently asked questions
Does JPG to PNG improve quality?
It can't restore detail the JPG compression already discarded, but it stops any further loss — every later save of the PNG is lossless.
Why is the PNG bigger than my JPG?
PNG stores the image losslessly, so photographs take more bytes. That's normal — you're trading size for exact pixels.
Are my files uploaded anywhere?
No. The whole conversion runs in your browser — your JPG files never leave your device, and there's nothing for a server to store or leak.
Is it free? Is there a watermark?
Yes, it's completely free — no signup, no watermark, no limits on how many JPG files you convert.
