Compress PDF

Reduce PDF file size for email, web upload, or storage without sacrificing readability. Choose from optimized presets (Screen, Web, Print) or fine-tune compression settings. Embedded images are re-encoded at your target quality — the single biggest size reduction for most PDFs. All compression happens locally for complete privacy.

Perfect for content migration, text analysis, accessibility, and data extraction workflows.

Redact PDF

Permanently remove sensitive information from PDF documents with true redaction. Unlike simple black boxes that hide but don't delete content, this tool removes the actual text bytes from the PDF — ensuring redacted content cannot be recovered through copy-paste, text extraction, or search. Essential for legal documents, confidential reports, privacy compliance, and secure information sharing.

Instant • Private

Repair Corrupt PDF

Recover and fix corrupted or damaged PDF files that won't open in standard viewers. The repair engine reconstructs broken internal structures including damaged cross-reference tables, missing end-of-file markers, and corrupt object streams. While it cannot restore content that is physically missing from the file, it can often recover accessible data from otherwise unreadable documents.

Reorder PDF Pages

Visually rearrange the pages of a PDF with an intuitive drag-and-drop interface. Move any page to a new position, reverse the entire document order, or swap two pages instantly. The original file remains untouched, ensuring your source document is always safe while you create a perfectly organized output.

Rotate PDF Pages

Permanently rotate pages in a PDF to fix orientation issues from scans or mobile photos. Apply 90° clockwise, 90° counter-clockwise, or 180° flips to all pages, specific page ranges, or just odd/even pages. The rotation is embedded directly in the PDF — it will display correctly in any viewer.

Instant • Private

Sign PDF

Add your signature to PDF documents for contracts, agreements, forms, and authorizations. Create signatures three ways: draw with your mouse or touchpad, type your name in a professional script font, or upload an existing signature image. Position anywhere on any page with drag-to-place precision.

Split PDF

Break a large PDF into smaller, more manageable files. Define custom page ranges to extract specific sections, split every N pages for equal distribution, or extract each page as its own file. Perfect for separating chapters, sharing specific sections, or reducing file sizes for email. All processing happens locally — your documents never touch a server.

PDF to CSV Converter

Convert the text in your PDF into a CSV file you can open in any spreadsheet app, import into a database, or process with a script. Each line on the page becomes a CSV row, and columns are split where there's a clear gap between values. Scanned, image-only PDFs are recognized with built-in OCR first, so even photographed documents can be turned into structured rows — entirely in your browser, with no uploads.

Instant • Private

PDF to Excel Converter

Turn the text in your PDF into an Excel spreadsheet you can open in Microsoft Excel, Google Sheets, or LibreOffice Calc. Each line on the page becomes a row, and columns are split where there's a clear gap between values.

Bank Statement to Excel Converter

Turn a bank or credit-card statement PDF into a tidy Excel spreadsheet with one click. Instead of dumping every line into rows, this converter finds the statement's column header — Date, Description, Withdrawal, Deposit, Balance and the like — anchors every transaction across every page to those same columns, and removes the header and page numbers that repeat on each page. You get a single, clean table with a bold, frozen header row and right-aligned amount columns, ready to sort and total. Scanned statements are recognized with built-in OCR first, and your file never leaves your device.
