How it works

Step 01

Drop in your PNG files

Add screenshots, logos, or graphics with transparency. Processing runs in your browser, so PNGs are never uploaded.

Step 02

Tune the quality

Move the slider to find a smaller file that still looks clean. Transparency is preserved at every quality level.

Step 03

Download the compressed PNG

Save the smaller file with its alpha channel intact. Original dimensions are kept unless you resize separately.

Use cases

App icons and favicons

Get PNG icons down to a few KB each for faster app bundles and lighter browser tabs.

Design mockups and wireframes

Share Figma exports or wireframe PNGs with clients over email or Slack without hitting attachment limits.

FAQ

Frequently asked questions

Yes. The alpha channel is preserved through compression, so transparent backgrounds stay transparent. This works for logos, icons, and any graphic with see-through areas.
