JPG to PNG Converter

Some tools and workflows simply insist on PNG. Design apps and document templates that expect a lossless source, systems that need an alpha channel, screenshot and diagram pipelines, and the odd upload form all ask for PNG specifically. If you only have a JPG, converting is the way to satisfy them.

It is worth being clear about what this does and does not do: PNG will store the image losslessly from here on, which is useful for repeated editing, but it cannot recover the detail JPG already discarded when the photo was first saved.

PNG is lossless, so it records every pixel exactly rather than using the space-saving compression JPG relies on. For a photograph that means the PNG is usually bigger — often two to four times the size of the JPG — because photographic detail does not compress well without loss.

For flat images, screenshots, and graphics with large areas of solid colour, PNG is far more efficient and the size difference shrinks or disappears. So the format is a good fit when the picture is a graphic or you need lossless editing, and a poor fit when you just want a small, viewable photo, where JPG stays the better choice.

Converting JPG to PNG does not improve the image; it preserves it. The pixels the JPG decoded to are written into the PNG untouched, so what you see is exactly the JPG, now in a lossless container.

That is the point when you plan to edit and re-save: further work on a PNG will not keep degrading the image the way re-saving a JPG does, because each JPG save compresses again. Start from the PNG and your edits stay clean, even though the original JPG compression is already baked in.

The JPG is decoded and re-encoded as PNG in your browser, with nothing uploaded and nothing kept after you close the page. There is no account, no watermark and no upload wait, so you can convert a single screenshot or a batch of images in one pass and download them right away. Because it runs locally, private images — documents, work drafts — never touch a server.
