Worth knowing before you convert
- This makes files bigger, and that is expected: PNG stores every pixel exactly, including detail your JPG had already discarded. On our reference image the file grew 507.1%. Convert this way when you need an editable or widely supported file — not to save space.

Your own file will land somewhere else — a photo, a screenshot and a flat logo compress very differently. What carries over is the direction and the rough scale.
Questions about JPG to PNG
How do I convert JPG to PNG?
Drop your JPG files onto the box above, pick a quality level if you want to override the automatic one, and press convert. The PNG files download straight back to you — a single file on its own, or a ZIP when you convert several at once.
Is converting JPG to PNG free?
Yes. There is no account, no watermark, and no per-file charge. Conversion runs on our servers, so it does not depend on how fast your own machine is.
Are my files stored anywhere?
No. Files are held in memory only while the conversion runs and are discarded the moment the result is sent back. Nothing is written to disk and nothing is written to a database.
Will the quality drop?
PNG stores every pixel it is given. It cannot restore detail that JPG already discarded, but it will not remove any more.
Why choose PNG over JPG?
Lossless compression with an alpha channel. Pixel-perfect, which also makes it the heaviest option for photographs. Logos, screenshots, and any image with sharp edges or transparency. Browser support: Universal.
