Compressing…
Metadata is removed by default (uncheck to keep EXIF). PNG keeps transparency; JPEG/WebP/AVIF use a white background when enabled. AVIF output requires a modern browser. Files never leave your device.

Does compressing a PNG keep transparency?
Yes. PNG output keeps the transparent background. Only JPEG output fills transparency with white.
How much smaller will my PNG get?
PNG is lossless, so the biggest savings come from scaling down oversized dimensions and stripping metadata. For much smaller files that keep transparency, switch the output to WebP.
Should I convert my PNG to JPG instead?
For photos, yes — JPG is far smaller. Keep PNG for logos, icons, screenshots and anything with transparency or sharp text.
Can I compress many PNGs at once?
Yes. Drop in as many files as you like and download them all when they're done.
Are my images uploaded?
No. Everything happens in your browser, so your files never leave your device.
