How to use this tool

  1. Upload or drag and drop your PDF file into the dropzone (up to 50 MB, 1000 pages).

  2. Enter the exact terms, names, account numbers, or phrases you wish to redact (separated by commas or new lines).

  3. Choose whether matching should be case-sensitive.

  4. Click Redact PDF to permanently excise the text streams, bake solid blackouts, and download your sanitized document.

  5. Burn the marks into the page with Flatten PDF, then restrict opening with Protect PDF.

Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

This is true cryptographic redaction. Amateur tools and basic preview software merely draw black rectangles over words without deleting them, leaving the text selectable and copyable. Elixuvo uses PyMuPDF's low-level engine to locate the exact character coordinate streams and permanently excise the font glyphs from the PDF definition.
No. Once redactions are applied, the underlying character codes, vector glyphs, and font mappings no longer exist in the PDF binary. Even if someone inspects the raw stream bytes or uses text extraction tools, the redacted words cannot be recovered.
Yes. You can supply as many phrases, names, email addresses, and identification numbers as needed, separated by commas or line breaks. Every matching occurrence across all pages will be sanitized in a single pass.
No. Only the specific coordinates matching your target terms are modified. Surrounding text, images, page layouts, margins, and vector sharpness remain completely intact.
No. All sanitization and byte-level purging operations run 100% in memory on the Elixuvo API. Files are streamed directly back to your browser and immediately purged from memory upon completion.
