Quiet PDF Reader sets a new standard in calm
Most readers ask for access, show ads and send your habits somewhere. Quiet PDF Reader does the opposite. It reads the PDFs you pick, remembers where you stopped, and gets out of the way.
Private by design
No ads, no analytics, and your documents are never uploaded.
No internet access
The app has no internet permission and never asks for all-files access.
Remembers your place
Reading positions, bookmarks and notes stay in private app storage.
Yours to clear
Clear history anytime. Your original PDFs are never deleted.
If you choose Share, a cloud save or another app, your chosen content goes to that app or provider, which follows its own privacy terms. Read the full privacy policy.
Bookmarks and notes, in your words
Name a bookmark “Important formula”, or leave it blank to use the page number. Add a note to any page, and find every bookmarked PDF in one list.
Find it in seconds
Search a document's text, see matches highlighted, and browse them with the page slider. Search needs Android 15 or later, and scanned or image-only PDFs can't be searched.
Convert on your phone, not in the cloud
Save PDF pages as PNG or JPG in a ZIP, or combine JPG and PNG images into one PDF. Conversion stays on this device, and you choose where each file is saved.
More than a reader
Annotate and draw
Mark up pages with drawings and notes. Drafts stay in private app storage.
Fill and sign
Fill forms and sign on your device. Drafts stay private until you save or share.
OCR on device
Recognise text in scans without leaving your phone. Language models install into private storage.
Read aloud
Listen with the offline voices installed on your phone.
Protected export
Export a copy with a new password. Your original file is unchanged, and reading passwords clear when you lock.
Collections and tabs
Group your PDFs, keep several tabs open, and return to each reading position.
Take a look inside
Made for how you read
Commuting
Works offline. Tap for full screen, then long press the lock so a bump can't change the controls.
After dark
Switch to night mode and keep the screen on while you read, without squinting at a bright page.
Paperwork
Turn photos into a single PDF, fill and sign forms, print the whole document, or share it to any app you choose.
Questions, answered
What to know before you install.
Does it need an internet connection?
No. The app has no internet permission, so reading, annotations, OCR and conversion all happen on your device. If you share a file or save to a cloud provider, the app you choose handles that transfer.
What permissions does it ask for?
It has no internet permission and doesn't request all-files access. You pick each file through Android's picker.
Which Android versions are supported?
Android 6.0 and later. Find in PDF and Text view need Android 15 or later; scrolling and jumping to a page work everywhere.
Can it open password-protected PDFs?
Yes, you can read them. Converting them isn't available in this release, and on older Android versions password-opened files are supported up to 32 MB.
Does it work with scanned PDFs?
Search works on PDFs with selectable text, so scans can't be searched directly. For scans, the app has OCR that runs on your device, and results stay in session memory until you copy, share or save them.
Who makes Quiet PDF Reader?
It is published by Rakibul Hashan. For questions, write to hello@rakibulhashanrabbi.com.
How do I clear my reading history?
Open Privacy and clear history in the app. It removes saved links, positions, bookmarks, notes and covers. Your original PDFs and exported files stay untouched.
