About this tool

Redact confidential details like account numbers, home addresses, phone numbers, and signatures from PDFs and photos. Black boxes are permanently baked into flattened image layers so underlying text streams cannot be selected or copied. All redaction runs in local browser memory without uploading sensitive files.

Redact a Photo or PDF is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.

  • No upload: redaction permanently flattens documents into image layers right on your device with zero cloud upload.
  • Speed: processing happens instantly on your device with no upload or download delays.
  • Quality: you can check your file before saving, and the original remains unchanged.
FAQ
Is my file uploaded to an online server for redaction?

No. The entire redaction process runs in your browser memory via WebAssembly and HTML5 Canvas. Your sensitive document never leaves your device.

Can someone copy the blacked-out text or remove the boxes?

No. Unlike basic PDF editors that draw rectangles over vector text, Weesize flattens pages into raster images before applying redactions. There is zero underlying text layer in the output PDF.

Does redacting an image remove camera GPS and EXIF data?

Yes. Exported JPG and PNG images are freshly re-encoded from canvas, permanently stripping all embedded EXIF tags and GPS coordinates.

Can I redact multi-page PDF documents?

Yes. You can navigate between pages, apply redactions on any page, and export a multi-page flattened PDF or a ZIP containing all page images.

Can I run this redaction tool offline without internet?

Yes. Once loaded, Weesize operates completely offline. You can disconnect Wi-Fi and black out sensitive data with zero network calls.
