Frequently Asked Questions
- What's the difference between blur and pixelate?
- Blur applies a smooth gaussian effect that makes content unreadable while looking natural. Pixelate creates a blocky mosaic pattern — more obvious but stronger redaction. Both permanently obscure the original content on export.
- Can the blur be reversed?
- No. Once you export the image, the blur or pixelation is permanently baked in. The original pixels behind the blurred area are discarded, so the content cannot be recovered.
- Is my image uploaded to a server?
- No. All processing happens entirely in your browser using JavaScript. Your image never leaves your device, making it safe for sensitive documents.
