InkStack
Voice, notes & photos to PDF
Free · Designed for iPad. Not verified for macOS.
Inkstack is the on-device PDF maker for iPhone: write it, say it, or snap it — then save a PDF without uploading your files.
CREATE A PDF
• Text to PDF — type notes or a letter and export a clean multi-page document
• Voice to PDF — dictate, edit the transcript, then save
• Image to PDF — photos or camera; each picture becomes a page
EDIT WHAT YOU ALREADY HAVE
• Merge PDFs into one file
• Split a PDF into single pages
• Rotate, reorder, or delete the pages you tap
• Drag to highlight exact words — not a random box on page one
• Sign with your finger
• Fill forms and add a watermark
• Search text in the document
PROTECT & SHARE
• Password-protect before you send
• Compress for email and WhatsApp
• OCR for scans so text is selectable
• Print, share, or export pages as images
• Saved files live in the Files tab on this iPhone
WHY INKSTACK
No account. No cloud for your documents. Create from notes, voice, or photos first — then merge, split, sign, and lock. The app is free and supported by labeled ads. Ads never cover buttons or the keyboard. Tools are not locked behind ads.
