About this app

Fast PDF Reader brings a PDF reader and Office file viewer together in one organized Android app. Open supported documents, scan paper into PDF, review files with AI, or listen with Read Aloud.

Review a report, open a presentation, listen to notes, or save a receipt without switching between document apps.

What you can do with Fast PDF Reader:
• Read PDF files: Open PDFs from storage, Downloads, email, chat apps, or Android’s file picker. Search text, zoom, follow links, use a table of contents when available, copy selectable text, and jump to a page.
• View Office files: Open supported Word, Excel, PowerPoint, and text files, including DOC/DOCX, XLS/XLSX, PPT/PPTX, and TXT. These formats are available for viewing; editing Office document text is not supported.
• Understand documents with AI: Use AI Summary for a structured overview or Ask PDF to explore document text with questions. AI features require an internet connection.
• Listen with Read Aloud: Hear supported document text using the text-to-speech service selected on your Android device, with playback and reading-speed controls.
• Scan documents: Capture paper with the camera or import images, review page edges, arrange pages, and save the result as a PDF.
• Annotate PDFs: Highlight, underline, strike out, draw with ink, and remove supported annotations.
• Organize files: Return to recent documents, mark favorites, use tags, view file details, rename files, and continue from your last reading position.
• Use PDF tools: Create PDFs from images, compress image-heavy PDFs, add or remove a PDF password, print, and share through Android.

Read and review PDFs your way

Choose vertical, horizontal, single-page, or continuous reading. Adjust brightness and appearance, use full screen, and resume where you stopped. Search documents, follow links, jump to a page, or use the table of contents when available.

Open Office and text files

View Word documents, Excel spreadsheets, PowerPoint presentations, and TXT files in the same library as your PDFs. Complex layouts, fonts, formulas, animations, and embedded content may appear differently from the original. Office document editing is not supported.

Scan, create, and organize documents

Turn camera captures or gallery images into a PDF. Correct page edges, reorder pages, and save to your device. Use favorites, tags, file details, reading history, and recent files to return to important documents.

Use AI and online conversion when connected

AI Summary, Ask PDF, and PDF-to-Word require an internet connection. With your permission, the AI features send extracted document text—and, for Ask PDF, your questions—for online processing. AI responses may be incomplete or inaccurate, so verify important details against the original. PDF-to-Word sends a supported PDF for online conversion and returns a Word document to open, save, or share.

Listen with your Android text-to-speech service

Read Aloud uses your selected Android text-to-speech service. Languages, voices, and network requirements depend on the installed TTS engine and voice. It requires extractable text and may not work with image-only or scanned pages without a text layer.

Offline and online availability

Core reading, scanning, annotation, organization, and many PDF tools can work offline without an account. AI and PDF-to-Word features need internet access. Network access may also support ads, purchases, notifications, and selected device services.

Download Fast PDF Reader to read PDF and Office files, scan documents, summarize with AI, ask questions, and listen with Read Aloud.

Ratings and reviews

Great PDF App. For a tech novice and cognitively challenged individual, it is easy to navigate and most of all find my save files. Very intuitive with none of the frustration I experienced with many others. Grateful for free access to so many features. I am always hesitant to pay for an App then find out it's a dud. But, I've been using this one for about two years now. I don't use it for routine school or business activities but whenever I have to I have not been disappointed.

Love this app. I used it to download a magazine and make it in PDF form given permission from the creators of the magazine called the Fish Sniffer. I was featured in the magazine. I was given a direct link and it had the option to download a PDF version. Now to the app part of things, it's smooth, fast, organized, easy layout, a breeze to use. Thank you!

This app allowed me to use it without a login, which was very nice. It seems one frequently is required to establish an acct before you can use it the first time. That's very annoying to me since I don't WANT an acct if the app is useless to me or full of bugs. Thus I prefer to try out the app without attaching my email, signing up, surrendering my first born, etc. So, I found Fast PDF Reader 2022 useful and simple to use. With no strings attached.
