Security

Processing location. Compression, resizing, merging and PDF rebuilding all run in your browser. The page loads once, then works offline in practice — useful on an unstable mobile connection.

File validation. We check the actual contents of a file rather than trusting its extension, so a mislabelled file is caught before processing and explained in plain language.

What we avoid. No file is executed. No download links are generated on a public server, and nothing you prepare here is reachable by a URL that anyone could guess, because nothing is stored anywhere but your own device.

Signatures on PDFs. A drawn or pasted signature image is a visual mark. It is not an Aadhaar eSign and not a Digital Signature Certificate, and we do not present it as either.
