Why convert JPG to PNG?
JPG (JPEG) is a lossy format designed for photographs — it compresses well but discards some image data every time it's saved, and it has no support for transparency. PNG is lossless and supports a full alpha channel, which makes it the better choice whenever you need to edit an image repeatedly, overlay it on other content, or add a transparent background without visible compression artifacts.
Good reasons to switch to PNG
- Editing and re-saving — PNG won't introduce new compression artifacts each time you save.
- Logos, icons, and graphics — sharp edges and text stay crisp; JPG tends to blur or "ring" around hard edges.
- Transparency — PNG supports it; JPG doesn't.
- Screenshots and UI captures — PNG preserves flat colors and text without JPG's blocky artifacts.
What to expect
Because JPG is lossy, converting to PNG cannot recover detail the JPG compression already discarded — it simply stops any further quality loss. The output file will also be larger than the original JPG, since PNG doesn't use JPG's aggressive photographic compression. This converter draws your JPG onto a canvas and re-encodes it as PNG entirely inside your browser tab — no upload involved.
