PNG · 191 KBJPG is a lossy photo format with no transparency; PNG is lossless and supports an alpha channel. Converting to PNG stops any further quality loss and gives you a file you can edit or composite. The trade-off: a photo saved as PNG is usually larger than the original JPG. The conversion runs over HTTPS and needs no signup. We delete your files within 24 hours.
A JPG has no transparency, so converting to PNG won't create a transparent background. It only keeps the solid one that's already there. Expect a photo saved as PNG to be larger than the JPG.

Short answers specific to this page. The tool above settles most of them in a second.
Every route in and out runs on the same engine and the same rules. Each card is its own page.
The safe upgrade. Around a third smaller at matching quality, and readable essentially everywhere.
Roughly half the bytes of WebP on most photos. Slower to encode, worth it at scale.
For photographic PNGs that never needed transparency. We flatten any alpha onto a solid background.
Keeps the alpha channel and still cuts real weight. The least disruptive way off PNG.
Transparency survives and size collapses. Check thin type and 1px strokes in the preview first.
Keeps transparency for editors and pipelines that won't read WebP. Bigger file, no further loss.
