Compress PNG
Make PNG pictures smaller for email, websites and uploads.
How to use it
- Add your file. Drop it on the box above or tap it to pick it from your device.
- Let it work. Drop your PNGs. Each comes back as a WebP, usually far smaller with the same transparency.
- Download. Press Download. Nothing was uploaded, so nothing is stored anywhere.
What it does
PNG is lossless, so it can't be squeezed much without changing format. WebP keeps transparency and is typically 50 to 80% smaller.
When to use it
Sending photos by email, speeding up a website, fitting upload limits or freeing space on your phone.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
