Pull the text, tables and images out of any PDF — entirely on your device. Nothing is uploaded, so private documents stay private. PDFExtract reads a PDF's own text layer when it has one, and falls back to on-device OCR when it doesn't. Either way it rebuilds what it finds as clean Markdown you can paste straight into your notes, docs or knowledge base. Every import becomes a project you can reopen, review and run again with different settings. WHAT IT DOES - Import standard and password-protected PDFs - Extract the text layer from selectable PDFs - On-device OCR for scanned and image-only pages - Rebuild detected tables as real Markdown tables - Pull embedded images out of pages at their original resolution - Preview the original PDF, the extracted images and the rendered Markdown - Copy Markdown, share it as a file, or export a whole project as a ZIP - Tune OCR: recognition level, render resolution up to 600 DPI, recognition languages, automatic language detection and language correction - Choose the Markdown output style, page headings and document title - Keep every import as a project you can revisit and re-extract WHAT'S FREE - Text, Markdown and OCR for the first 5 pages of a document - The first 10 extracted images of a project - Every OCR and Markdown setting - Copy the Markdown or share it as a file PDFEXTRACT PRO UNLOCKS - Every page of a document, however long it runs - Every extracted image, unblurred and shareable - Tables rebuilt as Markdown tables instead of run-together lines - Batch ZIP export of the Markdown and all extracted images SUBSCRIPTION DETAILS PDFExtract Pro is available as a monthly subscription, a yearly subscription, or a one-time Lifetime purchase. - Monthly: auto-renews every month - Yearly: auto-renews every year - Lifetime: a single payment, never renews Prices are shown in the app and vary by region.
