## Frequently asked questions

### Why convert JPG to PNG?

PNG is lossless, so any further edits don't degrade quality. PNG also supports transparency, which JPG does not. For photos that will be re-saved many times, PNG keeps the source clean.

### Will the file get bigger?

Usually yes. PNG is lossless and JPG is highly compressed, so PNG output is often several times larger. That's the trade-off for lossless storage.

### Can I add transparency after converting?

Yes. PNG supports an alpha channel, so once you open the result in an image editor you can erase to transparency.

### Is there a size limit?

Common photo sizes work fine. Very large files (50 MB+) may be rejected; resize the source down first.
