3 The boxes
A page with a box is redrawn as a picture with the boxes painted on, so nothing under them is left in the file; its other text can no longer be selected or searched. Pages without boxes stay as they are.
The page
How to black out Aadhaar, PAN or any detail in a PDF
- Choose the PDF (or drop it on the box). Its text is read at once, on your phone.
- Aadhaar numbers, PAN, mobile numbers and email addresses are found for you and listed with their page and the words around them. Type names or anything else to find (a name, an account number). Untick anything that should stay, and tap Show to see a find on its page.
- For anything else (a photo, a signature, a stamp, a scanned page), drag a box over it on the page. On a phone, tap Draw boxes first, so the page still scrolls when you are not drawing. From a keyboard, use Add a box, then the arrow keys to move it, Shift and the arrow keys to change its size, and Delete to remove it.
- Choose black or white boxes and how sharp the redrawn pages are (200 DPI, or 300 DPI for fine print), then tap Redact and save. Download the PDF or share it.
Everything happens in your browser: the PDF is never uploaded to ap7am or anywhere else. The new file keeps
your PDF's name, such as application-redacted.pdf.
Why it is gone for good, not just covered
A black rectangle drawn over text in a PDF editor (or a phone's markup) only hides it: the text is still in the file, and anyone can copy it out from under the box. Here, every page with a box is drawn again as a picture at 200 DPI (300 if you choose), the boxes are painted solid onto that picture, and the picture becomes the page, at the same size. Nothing that was under a box is left: no text, no picture data. Pages without boxes are copied as they are, with their text.
The tool also checks its own work: it opens the new PDF again and reads the text of every redacted page. There must be none, or the file is not offered. When the check passes, it says Checked: nothing under the boxes can be read.
From the whole file it also removes what is not seen on the pages but travels with the file:
- the document's details: title, author, subject, keywords, the app that made it, dates;
- hidden XMP data, scripts (JavaScript), attached files and bookmarks;
- links and form fields on the redacted pages (they are now part of the picture);
- pictures and fonts that only a redacted page used, even where the PDF lists them for every page.
What it finds
| Find | What it looks for |
|---|---|
| Aadhaar |
12 digits starting 2 to 9, as 2345 6789 0124 or 234567890124, whose last
digit is the right check digit (UIDAI's Verhoeff check), so a random 12-digit number is not marked.
Tick
Keep the last 4 digits for the masked style UIDAI uses: XXXX XXXX 0124
.
|
| PAN |
Five letters, four digits, a letter, such as ABCPE1234F (the fourth letter says who
holds it).
|
| Mobile | 10 digits starting 6 to 9, with or without +91, 91 or 0, with spaces or dashes anywhere. |
Addresses such as name@gmail.com.
| |
| Your words | Any name or phrase, in any capitals, even when the PDF splits it into pieces or across a line break. “Whole words only” finds Kumar but not Kumari. |
What it cannot do
- A scanned page or a photo has no text to search: the tool says which pages, and you draw boxes there yourself.
- Some PDFs, often older Telugu ones, store their letters in a way that cannot be read back; words on them may not be found. Look through every page and draw boxes where needed.
- The redacted pages become pictures: their other text can no longer be selected or searched, and the file gets larger. To bring it under a form's limit, use Compress PDF.
- On the pages kept as they are, links to other pages are removed, and form fields show their answers but can no longer be filled in.
Questions
Can someone remove the black boxes later?
No. The boxes are not a layer on top: the page itself is a new picture with the boxes painted in, and the original text and pictures of that page are not in the file at all.
Should I share a masked Aadhaar?
Where a form or an office does not need your full Aadhaar number, UIDAI suggests using a masked Aadhaar, which shows only the last four digits. Tick “Keep the last 4 digits” to make a copy like that from any PDF.
Can I redact a scanned PDF or a photo of a card?
Yes, by drawing boxes: a scan has no text, so nothing can be found for you. The page is redrawn with your boxes, and what was under them is gone.
My PDF is locked with a password. Can it be redacted?
Yes: type the password when asked (it stays on your device). A locked PDF's pages are all saved as pictures (the pages without boxes at 150 DPI), and the new PDF has no password.
How do I check the result myself?
Open the new PDF and try to select or search the blacked-out text: there is none on those pages. You can also compare it with the original in Compare PDF.
Is my PDF uploaded or stored?
No. It is read and redacted in your browser; nothing is sent to ap7am or anywhere else.
To keep only some pages, use Split PDF. Cropping a page ( Crop PDF) only hides what is outside the box; to remove details, redact them here.

Redacted on your device: your PDF is never uploaded. Pages with redactions are saved as pictures, so what was under the boxes is gone for good. Check every page before you share it.
