What it does

Everything a scanner app should do — and nothing it shouldn't.

Items marked P are part of Zx Premium. Everything else is free, with no page or time limits on scanning.

Scan with auto edge detection

Point at the page; the edges are found and straightened for you. Colour, greyscale or black & white. Up to 10 pages per scan free, 100 with Premium.

Share in a set size P

Under 100 KB, 200 KB, 500 KB or 1 MB — straight from the share sheet. Built for the government portal that says “max 200 KB”.

Lock files & folders

Password-protect PDFs and whole folders, then open them with your fingerprint or face. The password stays encrypted in your phone’s secure hardware.

New PDF — type one from scratch

Write a letter or a note, drop in photos, and save it as a real text PDF. Bold, italic and justified text with Premium. Hindi and English both shape correctly.

Combine, split, compress

Merge PDFs into one, pull out the pages you need, or shrink a file. Free for small jobs; unlimited with Premium.

Extract text (OCR) P

Turn a scanned page into editable text — English and Hindi in one pass — without the page ever leaving the phone.

Draw, write, edit pages

Sign, highlight or add text boxes. Reorder, rotate, crop, filter, erase and retake pages with undo and redo.

Folders, search, quick preview

Starter folders for ID cards, vehicle and academic documents; search every file by name; tap a thumbnail to peek before opening.

Backup to storage you choose

One zip of all your PDFs, saved wherever you like — a folder, a card, your own cloud. Restore on any phone. We never see it.

You don’t have to take our word for it

Check the permissions yourself.

Android lists every permission an app asks for. Zx Scanner asks for the camera and your photos — and nothing that could carry a document off your phone.

CAMERA

To scan

Used only while you are scanning. No photo is taken without you pressing the button.

READ_MEDIA_IMAGES

To import

So you can turn photos already on your phone into PDFs, or insert them into a typed document.

USE_BIOMETRIC

To unlock

Lets you open locked files with your fingerprint or face. Android only tells the app “yes” or “no”; the app never sees your fingerprint.

INTERNET

Not requested.

The app has no way to send anything anywhere. Scanning, OCR, compression and locking all happen on the device.

What this means in practice

Your documents live in the app’s own storage on your phone. They leave only when you share, print or back them up. Premium is sold through Google Play Billing, so we never see your card details either.

The full policy

Plain language, no surprises. Read the full privacy policy.

Why we built it

Built for the upload box that says “max 200 KB”.

Anyone who has applied to an Indian government portal, a university admission form or a recruitment site knows the routine. The form wants your marksheet as a PDF under a set size. Your scan is 4 MB. The upload fails. So you search for a website that compresses PDFs.

Uploading your marksheet to a random compression site is exactly the thing you should not do — it carries your name, your photo and your roll number.

Zx Scanner is built so you never have to. Scanning, text recognition and compression all happen on your phone. Your documents are never uploaded anywhere in order to be processed, because there is nowhere for them to be uploaded to.

Questions

Frequently asked.

Where are my documents stored?

In Zx Scanner’s own private storage on your phone. Nothing is copied to any server — the app doesn’t have the internet permission, so it couldn’t even if it wanted to. Use Backup to save a zip of everything to a place you choose.

Does it work without internet?

Yes, completely. Scanning, editing, OCR, compression and locking all run on the phone. The only time Google Play is involved is when you buy Premium.

What happens if I forget a folder password?

There is no recovery — not even for us, because the password never leaves your phone. If you set up fingerprint unlock for that folder, you can still open it that way. Keep a note of your passwords somewhere safe.

How do I cancel Premium?

Open the Google Play Store app → your profile → Payments & subscriptions → Subscriptions → Zx Premium → Cancel. You keep Premium until the end of the period you paid for, and your documents are never affected.

Does it support Hindi?

Yes. OCR reads English and Hindi (Devanagari) in one pass, and typed PDFs render Hindi text correctly.

Will it work on my tablet or foldable?

Yes — the layout adapts to larger and unfolded screens. Android 10 or newer is required.

Why is there no iPhone version?

Zx Scanner is built by one developer and is Android-only for now.
