Best Pdf Reader Apps for Android (2026)

Xodo is the one we recommend first to almost everyone. It opens huge files fast, scrolls smoothly, and packs annotation, form filling, and signing into a free app with no nagging watermarks. In our testing the night mode genuinely helped late reading sessions, and tabbed viewing let us flip between two documents. It suits students and anyone who marks up PDFs but does not want to pay a subscription.

Acrobat is the safe default, and for good reason. It renders complex layouts faithfully, syncs across devices through your Adobe account, and the Liquid Mode reflows dense pages so text actually fits a phone screen. Reading and basic commenting are free. Editing text and exporting to Word need a paid plan. If you live in Adobe tools already, it feels like home and rarely surprises you.

Librera is a reader's reader. It handles PDF alongside EPUB, MOBI, and a dozen other formats, with deep typography controls, custom themes, and a built in text to speech voice for hands free reading. It is free with optional ads you can remove cheaply. We loved how it remembered our place across a whole shelf of books, making it a quiet favorite for heavy bedtime readers and offline libraries.

If your documents already live in Drive, the built in viewer is the path of least resistance. Tap a PDF and it opens instantly, no extra install, with search and basic sharing right there. It is completely free. You will not annotate or sign here, but for quick reference, receipts, and shared work files it is the most frictionless way to read a PDF on Android without juggling another app.

Foxit punches above its weight with crisp rendering and a surprisingly capable free tier. We found the reading flow clean and the annotation tools responsive even on older phones. It also signs documents and fills forms without forcing an account. A subscription unlocks editing and conversion. For people who want something more powerful than a plain viewer but lighter than Adobe, Foxit hits a comfortable middle.

The Microsoft 365 app quietly doubles as a solid PDF reader, which makes sense if your day runs on Word and Excel. It opens PDFs cleanly, lets you sign and annotate, and can even turn a phone photo into a PDF. It is free for personal use, with more under a subscription. We reach for it when a document arrives in a Teams or Outlook thread and we just want to read it in place.

WPS bundles a genuinely good PDF reader inside a full office suite. Opening, searching, and night reading all feel polished, and it converts PDF to Word or images without sending you to a website. It is free with ads, and a Premium tier clears them. We like it for travel, since one app then covers reading a contract, editing a spreadsheet, and signing a form on the same flight.

Kdan's PDF Reader leans into annotation, with a satisfying set of highlight, ink, and shape tools that feel made for a stylus on a tablet. Reading is smooth and the page thumbnails make navigating long files painless. The core app is free, with cloud storage and advanced editing behind a plan. If you study from PDFs or mark up drafts, this one rewards you the more you use it.

MuPDF Mini is the minimalist's choice, an open source viewer that is tiny, free, and completely ad free. There is no clutter, no account, just fast accurate rendering of PDF, XPS, and several ebook formats. We keep it on lighter phones as a backup because it launches almost instantly and never phones home. It will not annotate, but for pure private reading it is hard to beat.

On a Galaxy phone, the bundled My Files app opens PDFs without you installing anything, and pairs nicely with the S Pen for quick highlights on supported models. It is free and already there. The reading experience is plain but reliable, and it keeps documents organized alongside the rest of your storage. For Samsung owners who only open the odd PDF, it is often all you actually need.

Smallpdf grew from a popular web tool into a tidy Android app, and it shines when reading is only half the job. You can compress, merge, convert, and sign right after opening a file. Reading and a handful of tasks are free, with a Pro tier for heavier use. We found it ideal for people who often receive a PDF and then need to do one quick thing to it before sending it on.

OfficeSuite offers a comfortable, well laid out PDF reader as part of its broader productivity package. Rendering is sharp, and it handles annotation, signatures, and conversion in one place. The reader works free, with a subscription expanding the editing side. We appreciated the clean interface on a tablet, where reviewing a long report felt closer to a desktop than a phone, without the bloat some suites carry.
