Convert JPG to PNG
PNG stores pixels losslessly, which makes it a good archival or editing format — but it will not recover detail the original JPG already discarded.

Expect a larger file
A JPG photo converted to PNG almost always gets bigger, often several times over, because lossless compression can't throw anything away. Convert to PNG when you need transparency support or an exact-pixel intermediate, not to save space.
FAQ
Frequently asked questions
- Does converting JPG to PNG improve quality?
- No. It preserves exactly what the JPG contained, including any compression artefacts already baked in.
- Why is my PNG so much bigger?
- PNG is lossless, so photographic detail and JPG noise both have to be stored precisely. That takes far more bytes than lossy JPG encoding.
- Will the PNG have a transparent background?
- Not automatically — a JPG has no transparency information. You can set a background colour or add padding in the editor.
- Are my images uploaded to a server?
- No. Every step — decoding, cropping, resizing and encoding — runs in your browser using the Canvas API. The image file never leaves your device, so nothing is stored or transmitted by us.
