LensoraFree Android app · Document scanner · PDF tools
Scan receipts and documents to clean PDFs. Nothing leaves your phone.
Lensora is a document scanner for Android. It scans receipts, bills and pages with automatic edge detection, reads them with on-device OCR and files each one under a category such as Groceries, Utilities or Travel. Merge, split, crop, rotate and number pages, or turn a Word file into a PDF. Your files stay in your pocket.
What it does
A receipt scanner first, a PDF toolbox second.
Every tool runs locally using Google ML Kit and pdf-lib. There is no upload step, no cloud queue, no account to create.
-
01
Scan to PDF with automatic edge detection
Point the camera at a receipt, bill, invoice or page. Lensora finds the edges, fixes the perspective, cleans the image and builds a PDF, one page or many.
-
02
On-device OCR
Text is recognised on the phone, so Lensora can read a bill without the bill ever leaving it.
-
03
Categorize bills, receipts and documents
Every scan is filed under a category. OCR suggests one automatically from the text on the page, you can change it with a tap, and the Home screen filters your library by category so month-end expenses are a scroll, not a search.
- Business Meal
- Office Supplies
- Travel
- Utilities
- Groceries
- Other
-
04
Merge & split PDFs
Combine documents into one PDF or break a PDF into single pages.
-
05
Organize, rotate, crop
Reorder pages, fix orientation, trim margins and add page numbers.
-
06
Word to PDF and more
Read a Word (.docx) file and save it as a PDF. Also images to PDF, PDF to images and PDF to text. Print through the system dialog.
-
07
QR scanner
Read links, contact details and Wi-Fi codes. Actions happen only when you tap them.
-
08
Open with, share out
Lensora appears in Android's "Open with" list for PDF and Word (.docx) files and hands finished files to the system share sheet, so they go only where you send them.
In the app
Three screens, no learning curve.
Scan or import, name it and pick a category, then use any PDF tool. These are real screenshots from the Android app.

PDF tools, all offline. Merge, split, rotate, organize, crop and number pages.
-
Free, with optional ads. Two free credits a day; watch a rewarded ad only if you want more.
How it stays free
Credits, explained plainly.
One credit is used each time you scan or run a PDF tool. Importing a PDF is free. There are no forced full-screen ads and nothing is sold inside the app today.
Free credits every day. They reset at midnight on your device.
Per rewarded ad you choose to watch. Earned credits never expire.
Credits work only inside Lensora. They cannot be bought, sold or transferred.
Privacy, in one screen
Your documents are yours. We built it so we can't see them.
Lensora has no servers, no sign-in and no analytics SDK. The only data that leaves the phone is the advertising data used by Google AdMob when you choose to watch a rewarded ad, and in the EEA, UK and Switzerland that happens only after you consent.
- Scans, PDFs and OCR text are stored in private app storage on your device.
- Camera is used only while you scan. Lensora never records audio.
- Deleting a document deletes the file, not just the list entry. Uninstalling removes everything.
- Ad consent can be changed any time under Tools → Privacy Policy → Ad privacy options.
Questions
Quick answers.
More help, including permissions and troubleshooting, is on the support page.
Is Lensora free?
Yes. Lensora is free to download and use. You get 2 free credits every day, and each scan or PDF tool uses one credit. If you want more, you can choose to watch a rewarded ad to earn an extra credit that never expires. There are no forced full-screen ads and nothing is sold inside the app.
Are my documents uploaded to a server?
No. Scanning, text recognition, PDF editing and Word conversion all run on your phone, and files are kept in the app's private storage. Lensora has no account system and no servers. A file leaves your phone only when you share, print or export it yourself.
Does Lensora work offline?
Yes. Scanning, OCR, categorizing and every PDF tool work without an internet connection. A connection is needed only to load a rewarded ad if you choose to earn extra credits.
How does Lensora categorize receipts and bills?
After a scan, on-device OCR reads the text on the page and suggests a category: Business Meal, Office Supplies, Travel, Utilities, Groceries or Other. You can confirm or change it with one tap, and the Home screen filters your documents by category.
Can Lensora convert Word files to PDF?
Yes. Open a .docx file in Lensora to read it, then save it as a PDF. Lensora also appears in Android's Open with menu for Word and PDF files. Older .doc files are not supported.
Which devices does Lensora support?
Lensora runs on Android phones and tablets with Android 7.0 or newer and is available on Google Play. There is no iPhone version yet.
Turn the paper pile into tidy PDFs.
