ZeroPDF: Read & Edit PDFs

ZeroPDF brings PDF reading, annotations, signatures, page management and text recognition to your device. Open your documents without creating an account.

READ COMFORTABLY

Swipe between pages and pinch to zoom. Try sepia, green and dark reading colors or switch to text view. Keep recent documents and favorites close, and return to where you left off.

MARK THE TEXT YOU NEED

Tap a recognized word and drag the selection handles to preview a highlight, underline or strikeout. Release to apply. Add freehand ink, free highlights, notes, lines, arrows, rectangles and ellipses.

MAKE ANNOTATIONS YOURS

Choose a palette color or enter a HEX value. Adjust width and opacity, with defaults remembered for each tool. Select, move, duplicate or delete annotations, erase whole annotations, and undo or redo changes.

SIGN AND ORGANIZE

Draw your signature with a finger, then adjust its size and position. Reorder or delete pages, extract a selection, or merge PDFs. Save your edits as a new PDF.

OFFLINE TEXT RECOGNITION

Read and copy text from scanned PDFs using bundled Korean, Japanese and Latin OCR models. English and Spanish use the Latin model. Choose the document language in Settings. No recognition-model download is needed on first use.

DOCUMENTS ON YOUR DEVICE

Documents and OCR results are not uploaded to the developer's servers. You choose what to open, where to export and which app to share with. This version has no ads, in-app purchases or account registration.

BEFORE YOU START

• Edited copies in the app library retain source pages and editing data so annotations can be changed later.

• Reimporting an exported PDF alone does not restore its original editable annotation data.

• OCR accuracy depends on text size, clarity and layout. OCR extracts text from the current page; it does not add a searchable text layer to the entire PDF.

• Text view shows extracted text. It does not reproduce tables and images in a fully reflowed layout.

• Password-protected PDF unlocking and PDF encryption are not supported.

• Hand-drawn signatures are visual signatures, not certificate-based digital signatures.

Available in Korean, English, Japanese and Spanish. Requires Android 8.0 or later.
