Remove Digital Signatures from PDF Files Locally
Remove cryptographic digital signatures and password protection from PDF files securely in your browser. 100% private, 100% local processing.
Digital signatures in PDFs are cryptographic objects, not images. Most editors can only clear the visual marker, not remove the signed structure itself.
Certified PDFs use byte-range hashing. Any modification invalidates the document, which is why tools like Adobe Acrobat refuse removal.
SigRemove runs entirely in your browser using WebAssembly and removes signature objects directly, without uploading your file. Unlike "printing to PDF", which often rasterizes text and destroys accessibility, SigRemove preserves the document's original vector structure and text layer while specifically stripping the cryptographic signature.
No. Flattening usually merges layers into an image. SigRemove removes the hidden digital signature metadata objects while keeping the rest of the PDF content editable and sharp.
Yes. Since the processing happens in your browser's memory via WASM, your PDF never leaves your computer. No servers are involved.
