Sign & Secure
Sign & Secure PDF Tools — E-Sign, Password, Unlock
Lock a PDF you own, or remove a lock when you already know the password. Visible e-sign and watermark included.
Security tools that need the password you already have
Unlock and Remove Password only work if you type the existing password (UIDAI name+year, bank DOB, etc.). We do not brute-force Aadhaar, passbooks, or Form 16. Password Protect and Encrypt lock a file with a password you choose. E-Sign stamps a visible name and date — it is not a legally binding DSC / Aadhaar eSign from CCA.
Frequently asked questions
How do I use Sign & Secure online?
Upload on this page, wait a few seconds, and download the result. No signup.
Is it safe to upload my file here?
Uploads are stored outside the public web root, addressed by unguessable names, and deleted automatically after one hour. Download links expire so a leaked URL stops working.
Does this work on a phone?
Yes. The layout is one column on mobile with a 44px tap target for upload and download.
Will Hostinger Cloud run this tool?
Yes. Deploy on Hostinger Cloud and install Ghostscript for exact-size compress (`apt install ghostscript`, set GS_BIN=/usr/bin/gs). PHP converters (Word/Excel/JPG to PDF, unlock, merge, etc.) work without Ghostscript. PDF→JPG/PNG and scan OCR need Ghostscript/Tesseract on the Cloud box.
Will Hostinger shared hosting run this tool?
Most PHP tools yes. Shared plans usually lack Ghostscript — photo PDF compress still works; scan compress and PDF→image need Hostinger Cloud with GS installed.
Can I compress after converting?
Yes. Open Compress PDF and pick the KB cap printed on your form.
