01Why I built Siliph

Free for personal use, and private by design

Anupam Pradhan saw that many PDF sites keep people's private documents on their servers for longer than people expect. He built Siliph to protect that privacy, and he set one goal for it: to keep every tool free for personal use on the internet.

So every Siliph tool is free for personal use, with no sign-up and no watermark. Files that need the server are encrypted, handled only by machines and deleted automatically within 2 hours. Many tools never upload the file at all.

“I built Siliph because I didn't want my own documents sitting on someone else's server. Yours shouldn't either.”

Anupam Pradhan, founder of Siliph

Our privacy promise

Every file is encrypted.

On the way to us and while stored.

Your files are your business. Not ours.

No account. No sign-up. We never sell your files.

  • Encrypted, in transit and at rest

    Files travel to us over HTTPS (TLS) and are stored encrypted in Cloudflare R2.

  • No person looks at them

    Machines process your file to run the tool you chose. No one opens it.

  • Deleted within 2 hours

    Uploads are deleted automatically within 2 hours, or right away with "Delete files now".

  • Many tools never upload

    Tools such as merge, split and rotate run on your phone or computer, so the file stays with you.

Our privacy guarantee

Your files are never sold, never viewed by a person, and automatically deleted within 2 hours. Many tools never upload them at all.

AI features are the one exception: they send your document's text, your message or your photo to our AI providers for processing. Read the privacy policy for every service provider we use.
