Frequently asked questions

Is redaction permanent?

Yes, once you download the image, the redacted regions are permanently baked into the pixels. The original information cannot be recovered from the downloaded file.

Can I paste from clipboard?

Yes! Simply press Ctrl+V (Windows) or Cmd+V (Mac) to paste an image directly into the tool.

Does it work on mobile?

Yes, the tool is fully optimized for mobile devices. You can use touch and drag to select regions for redaction.

Can I undo my changes?

Yes, the tool stores up to 20 recent actions, allowing you to seamlessly undo mistakes or restart entirely.

Why does it export as PNG?

PNG is a lossless format, which prevents compression artifacts around the redacted regions and ensures the highest quality output.

Can someone recover the covered text?

The downloaded image contains the redaction pixels rather than the original layer. Still, review the exported file yourself before sharing sensitive information.

Can I redact several areas in one image?

Yes. Add as many rectangular redaction areas as needed, review the preview, and download the completed image when every sensitive region is covered.
