When to convert JPG to PNG
PNG is lossless, so it’s a good choice when you’ll edit and re-save an image repeatedly (each JPG save throws away a little more detail), or when a tool or platform specifically requires PNG. Note that converting a JPG to PNG won’t restore detail the JPEG compression already removed — it simply stops further loss from here on.
Expect a larger file
Because PNG stores every pixel exactly, a PNG of a photograph is usually much larger than the original JPG. That’s normal and expected — you’re trading size for a lossless, edit-friendly format. If size matters more, keep the image as JPG or compress it.
Frequently asked questions
Are my images uploaded to a server?
No. Decoding, any editing, and the conversion all run entirely in your browser. Your files never leave your device, so it even works offline once the page has loaded.
Can I convert several images at once?
Yes. Add as many as you like — a single image downloads directly, and multiple images are bundled into one .zip so you get everything in a single click.
Does converting JPG to PNG improve quality?
No. PNG is lossless, but it can’t recover detail that JPEG compression already discarded. It only prevents further quality loss in future saves.
