How it works

1
Upload

Drop the file. We check the type before processing.
2
Process

The matching engine runs in this request on the server.
3
Download

Grab a time-limited link. The copy is deleted within an hour.

Lock before you email KYC or bank scans

Built for Indian users who email Aadhaar, passbook, or marksheet scans. Choose a strong password, send it separately (SMS/WhatsApp), then share the locked PDF. Unlock later with Unlock PDF using the same key.

What you get

Mobile first

Large tap targets and a one-column upload on phones.

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 unless you asked for a watermark tool.

Known-password unlock only

Unlock decrypts with the password you type. We do not crack Aadhaar, passbooks, or bank files.

Hostinger-ready

Converters and page tools run in PHP on shared hosting. No VPS required for the tools we publish.

Then compress

After convert or unlock, hit an exact KB cap for SSC, UPSC, and job portals.

Frequently asked questions

How do I use Lock PDF India 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.

Is this a different tool from the main converter?

The converter itself is the same one in Convert Tools, PDF Tools, or Sign & Secure. This page is written for this file type and use case — password handling, size limits, and what the download contains — so you know what will happen before you upload.

Can I compress after converting?

Yes. Open Compress PDF and pick the KB cap printed on your form.
