Inkwell: PDF Reader & Scanner

Inkwell is a free PDF reader, PDF viewer, scanner and editor for Android: a document reader that also does the work. Open, read, sign and fill PDF files, scan paper to PDF, and have PDFs read aloud to you. No account needed, and the core tools work offline.

View and read PDFs
Open any PDF from your phone's storage, downloads, email or chat apps. Zoom smoothly, select and copy text, search inside the document, follow links, and jump to any page with thumbnails or the document's contents. Night and sepia reading modes are easy on the eyes. Inkwell remembers your page in every document, and a home-screen widget takes you straight back to where you stopped.

Read aloud (PDF to speech)
Tap Listen and Inkwell reads a PDF's text out loud with your phone's own voice, sentence by sentence, at the speed you choose. Good for studying, long reports and resting your eyes.

Scan documents to PDF
Turn paper into a PDF with your camera: receipts, contracts, homework, ID copies. Straighten the page with an adjustable crop and save a clean PDF. Convert photos and screenshots (JPG, PNG) to PDF in one step.

Sign and fill PDF forms
Draw your signature once and keep it on your phone, ready to sign your PDFs. Type into a PDF's form fields and save a finished copy, ready to send.

Annotate and highlight
Highlight, underline, strike out and draw on PDFs. Every highlight is collected in one place, across all your documents.

PDF tools
• Merge PDF: combine several files into one
• Split PDF: extract pages or break a file into parts
• Organize pages: reorder, rotate or delete
• Compress PDF: shrink large scans and photos for sharing
• Watermark PDF: stamp text on every page
• Remove a PDF password you know
• Print and share PDFs

Text recognition (OCR)
Turn a scanned page or a photographed document into text you can copy, search and share. Recognition runs on your phone: nothing is uploaded, and it works without internet.

Private and light
No sign-up and no cloud upload. Your files stay on your phone. Inkwell is a small download that runs well on older and budget phones.

Free, with ads
Inkwell is free and supported by ads. Reading, scanning, signing and the PDF tools are free. A few extras (read aloud and text recognition) unlock with Ink you earn by reading, or by watching a short ad. Very heavy signing (more than 5 documents in an hour) uses the same Ink-or-ad choice.
