convert JPG to PNG
Converting JPEG to PNG does not improve image quality, artifacts already introduced by JPEG compression remain. The legitimate reason to convert JPG to PNG is to preserve quality in subsequent edits: editing a PNG and saving as PNG does not accumulate loss, while editing a JPEG and saving as JPEG multiplies artifacts each cycle, because every save requantizes the JPEG's 8×8 blocks again, even with no visible change to the content.
Larger file, but no additional degradation in future edits.
Keep the PNG as master; export JPEG only for final distribution.
PNG avoids the "blocky" halo around letters that JPEG leaves on screen captures.
Transparency is filled with white, because the JPEG format does not support an alpha channel. If you need to preserve transparency, convert to PNG or WebP. The tool automatically warns you when this situation occurs.
No. Quality is frozen at the state it was in the JPEG. PNG only preserves that quality without adding more loss. To actually improve quality, you need the original high-resolution image.
Yes. PNG of a typical photograph is 3–8× larger than the equivalent JPEG. For storage, use JPEG or WebP. Reserve PNG for working files and projects with future editing.
Upload accepts up to 50 MB per file. The output also respects the browser's canvas limit: up to 40 million pixels and at most 16,384 px on any side. Photos from modern cameras sit well within those limits.

AVIF (not supported)
Converting a 6000px image without resizing is the classic mistake: the format changes but the file stays huge.
