How to use it

Open — drop a photo (JPG, PNG, WebP) or a PDF, or click to choose one. Screenshots can be pasted with Ctrl+V. PDFs open up to 50 pages.
Hide — drag a rectangle with Box, or paint over an area with Brush. Click a box to move it and drag a corner to resize. For a PDF, turn the pages and redact each one.
Style — choose Black out, Pixelate or Blur. For text such as ID or account numbers, Black out is the safe choice.
Check — use Preview result to see exactly what will be saved.
Save — Save file downloads a new file with _masked added to its name. Your original stays as it was.
Hidden areas are erased, not just covered. The photo's location and device data (EXIF) are removed, and PDF pages are saved as images so the hidden text can't be copied (the saved PDF's text can't be selected or searched).
