- Stick with PNG when transparency matters. Switch to WebP only if the receiving platform supports alpha channels.
- Use the background switcher to reveal fringe pixels before exporting.
- If you notice color shifts, ensure the source file is sRGB and avoid double compression.
- For logos, enable the corner radius slider to match your brand guidelines without adding artifacts.

- Add croppng.online to your home screen for instant access offline.
- All sliders and buttons have keyboard support; use Tab, Shift+Tab, and arrow keys to move the crop frame.
- Screen reader users can rely on descriptive labels and the result summary, which reads out crop bounds in real time.
- On touch devices, pinch-to-zoom the preview before adjusting handles for precision crop png control.

Preview feels slow: Reduce the number of simultaneous files or temporarily disable background gradients.
Download button missing: Ensure pop-up blockers are disabled for the session. Downloads never open new tabs or redirects.
Transparency lost: Verify that you are exporting as PNG. JPEG exports intentionally flatten backgrounds.
Need to revert: Use the reset button or load a saved preset to restore default crop png settings.
