Merge PDF: Compress & Sign

Merge PDF files, compress them, fill forms and sign. 20+ PDF tools on your phone: split, scan, OCR, JPG to PDF, protect and more. No account needed.

PDF Interleaver is a toolbox for everyday PDF jobs. Your PDF files are processed on your phone, and the app does not upload them.

Free with ads · one-time Pro · no subscription.

MERGE, COMPRESS AND SPLIT PDF
• Merge PDF: combine PDF files and images into one document
• Interleave PDFs: alternate the pages of two files to fix double-sided scans. Reverse either file if the backs came out last-page-first
• Compress PDF: make large files smaller, including to a target file size (results depend on the file)
• Split PDF: by page range, at a fixed interval, every page, or by file size

FILL, SIGN AND PROTECT
• Fill & Sign: add text, a date, check or cross marks and your signature, and fill PDF form fields. The signature is a visual overlay, not a digital certificate
• Protect PDF: password protect a file (AES-256)
• Unlock PDF: remove a password you know
• Redact PDF: mark text or areas. Marked pages are saved as images, so the text under the marks is not in the new file. Check the result before you share it
• Flatten PDF: flatten form fields or the whole page
• Remove annotations: clear comments, highlights and form fields

SCAN, CONVERT AND OCR
• Scan documents to PDF with the camera
• Images to PDF: turn JPG, PNG and WebP photos into a PDF, with page size, margins and several images per page
• PDF to JPG: pick pages, quality and resolution, or extract the images embedded in a PDF
• Extract Text (OCR): get text from a PDF, images or a scan, in Latin, Chinese, Devanagari, Japanese and Korean scripts, and save a searchable PDF
• Clean Scan: whiten backgrounds and darken text in color, grayscale or black and white
• ID Card Copy: front and back of an ID on one A4 page

ORGANIZE AND EDIT PAGES
• Organize pages: reorder, rotate, delete, duplicate, reverse the order, insert blank pages, images or pages from another PDF, with undo
• Page Layout: resize pages, fit 2 to 16 pages on a sheet, or make a booklet for duplex printing
• Page numbers: position, format and start number, plus header and footer text and Bates numbering
• Add watermark: text or image, with opacity, rotation and position
• Crop pages: manual or automatic
• Edit metadata: title, author, subject and keywords
• Remove empty pages: review the blank pages found before you save

READ AND OPEN
• Built-in PDF reader and viewer with zoom and a Recent files list
• Open PDFs from other apps, or share one to PDF Interleaver and pick a tool

BATCH MODE
• Apply Compress, Protect, Unlock, Watermark, Page Numbers or Flatten to up to 50 files in one run

FREE, WITH ADS, OR PRO
Most tools are free. Redact, Extract Text, Split by size and Compress to a target size unlock one save at a time when you watch a short ad. Previews and settings are always free. A one-time Pro purchase, with no subscription, also unlocks Page Layout, Batch mode, Searchable PDF and Bates numbering, covers the ad-unlocked tools, and removes the ads.

PRIVACY AND ADS
Your PDF files are processed on your phone and are not uploaded by the app. The document scanner and the text recognition models use Google ML Kit, delivered through Google Play services, and may download a component the first time you use them. Text recognition is not available for Cyrillic or Arabic. PDF Interleaver contains ads, including a short ad while a file is being processed. Ads and app analytics follow Google's consent rules, and you can change your choices in the app's privacy settings.

Available in 16 languages. Install PDF Interleaver and finish your next PDF job in a few taps.
