PNG compression notes
PNG is lossless by design, so strong size reduction often comes from resizing or converting to WebP/JPG.
This page keeps PNG input clear while still offering output formats that can reduce file size much more.

Privacy and limits
- PNG quality settings are browser-dependent.
- Use WebP or JPG output for stronger size reduction.
- Transparent areas become white when exporting to JPG.
Common use cases
- Optimizing screenshots for support articles
- Reducing transparent graphics for web pages
- Creating smaller UI captures for documentation
Format notes
- Keep PNG output when transparency and crisp edges are required.
- Use WebP output for smaller transparent web graphics.
- Use JPG only when a white background is acceptable.
Original test sample
- A 1440px app screenshot can often shrink when capped at 1200px and exported as WebP.
- A logo-like PNG may not shrink much unless dimensions are reduced or the output format changes.
