Frequently asked questions
Will I lose transparency converting to JPG?
Yes. JPG has no transparency channel, so transparent areas become white. Use PNG or WebP if you need to keep transparency.
Which format gives the smallest file?
Usually AVIF, then WebP, then JPG. PNG is lossless and best for graphics with text, but larger for photos.
Are my images uploaded anywhere?
No. Conversion runs entirely in your browser — nothing leaves your device.
