Frequently Asked Questions
Is it safe to upload my confidential documents here?
Yes, it is 100% secure. This tool utilizes client-side web technologies (HTML5/WebAssembly) to process files entirely inside your local browser. Your data is never uploaded to any external servers, ensuring absolute privacy.
What file formats does this online redaction tool support?
We support a wide range of file types including PDF documents, as well as popular image formats like JPG, JPEG, PNG, GIF, and WebP.
Will the blurred or blacked-out content remain reversible?
No. Once you apply the blur or solid mask and click download, our tool flattens the file layers permanently. The underlying original pixel data or text streams are permanently deleted, making it impossible for anyone to reverse-engineer or reveal the hidden information.
