-
3

Encrypt vs password protect
People search both phrases. This page is the encryption wording of the same lock tool. Choose a strong password. We apply PDF Standard security in PHP so Hostinger shared hosting works.
What you get
Mobile first
Large tap targets, one-column upload, and menus that collapse on a phone.
Auto-delete in 1 hour
Files sit outside the web root and are purged on a schedule.
No watermark
The download is your file. We do not stamp pages.
Then compress
After convert or merge, hit an exact KB cap for SSC, UPSC, and job portals.
Hostinger Cloud–ready
Runs on Hostinger Cloud with Ghostscript for exact KB compress. PHP tools work without VPS extras.
No account
No email wall. Fair-use rate limit only.
Frequently asked questions
How do I use Encrypt PDF 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.
