Convert JPG to PNG

How to convert JPG to PNG

1. Select one or more JPG files.
2. Press Convert.
3. Download the PNG, or the batch as a ZIP.

When this conversion makes sense

• Before editing. Every save of a JPEG re-compresses it. Working in PNG between edits means no further loss until you export.
• Software that demands PNG — some design tools, documentation pipelines and app-store asset checkers only accept PNG.
• Before adding transparency. A JPG cannot hold an alpha channel, so converting to PNG is step one in cutting out a background.
• Screenshots that arrived as JPG — converting stops further quality loss, though the JPEG artefacts already baked in cannot be removed.

An honest warning about file size

PNG is lossless, so it stores every pixel exactly — including all the compression artefacts already present in the JPG. A 1 MB photographic JPG commonly becomes a 6–10 MB PNG.

Converting to PNG does not improve quality. It cannot recover detail that JPEG discarded; it only stops any further loss. If you simply want a smaller file, you want compression or WebP, not PNG.

Does the image become transparent?

No. The PNG gains an alpha channel, but every pixel in it is fully opaque — because the source JPG had no transparency information to recover. You can now erase parts of it in an editor and the transparency will be preserved on save, which is usually the real reason people convert.
