Edit, annotate, sign, draw, highlight, scan with AI OCR, convert between 6 file formats, turn any URL into a PDF, merge documents — all in the browser, backed by Flask and PaddleOCR.
A complete PDF toolkit — AI-powered OCR, format conversion, annotation, and more, all in the browser.
Upload any scanned image or photo. PaddleOCR detects layout regions, recognises text in 80+ languages, and builds a properly sized PDF with text at the exact bounding-box positions — fully searchable and copy-pasteable.
Convert between 6 formats in one click. PaddleOCR powers Images→PDF with full layout detection. LibreOffice handles Word/PPT/Excel→PDF headlessly. pdf2docx and PyMuPDF round out the PDF-to-Office direction.
Firebase-backed sign-in with email, Google, or Microsoft. Sessions are verified server-side. Choose a subscription plan to unlock full access.
Drag-and-drop any PDF to open it. Zoom from 50–400%, flip pages with arrow keys or the mouse wheel, or jump directly to any page by typing the number.
Enter any URL and the Flask backend fires up a stealth headless Chromium browser — spoofed fingerprint, human-like mouse movement, Gaussian-jittered delays — to render the page and return a perfect PDF.
Toggle Edit Mode to reveal all text blocks as clickable hit areas. Click any text to open an inline editor with full font and colour controls. Original text is redacted, replacement is drawn in place — instantly visible, permanently saved.
Click anywhere to drop a text box. Style with font family, size, bold, italic, and colours.
Draw with mouse or finger. White pixels are knocked out so the signature sits cleanly over any content. Drag and resize on placement.
Drop any image directly onto the page at the exact spot you need. Resize with the corner handle, move freely, delete with a tap. Works across all pages — saved into the PDF on export via pdf-lib.
POST a comma-separated list of URLs to /api/urls-to-zip and receive a ZIP archive containing one PDF per URL plus a manifest.json. Up to 20 URLs in parallel.
⌘S embeds every annotation, edit, and stroke into a real, self-contained PDF via pdf-lib.
Hover any thumbnail to reveal the red badge. Click to remove with a smooth collapse — viewer stays on the nearest page.
Switch between single-page (wheel flips pages) and continuous scroll (all pages stacked vertically).
Log in with Google, Microsoft, or email via Firebase. Or hit "Try for free" for an instant guest session.
Drag in a PDF, paste a URL to capture a web page, scan images with AI OCR, or convert a Word/PPT/Excel file.
Add images, type text boxes, edit existing content, sign, draw, highlight, erase, or reorder pages.
Combine multiple PDFs into one. Drag to set order, click Merge — pdf-lib handles the byte-level join.
Press ⌘S or click Save PDF. All changes are burned into a proper PDF file and downloaded instantly.
