Everything you need, nothing you don't.
Google ML Kit auto-detects document edges, corrects perspective, and processes everything on-device.
Crop, rotate, brighten, or switch to grayscale — every edit can be undone months later. Original scan is never touched.
Scan multi-page contracts, reports, books. Reorder or delete pages. Export as a single PDF.
Combine any two documents into one. Append pages from an existing PDF. Preserve all edits.
Bring in external PDFs and edit them like camera scans. Rasterized at 200 DPI for sharp text.
Draw or place a saved signature on any page. Handwritten mark embedded directly in the PDF.
Add text notes or colour highlights to any page. Drag and resize to position exactly.
One tap auto-optimizes any page: grayscale + contrast boost. Works on ~90% of standard documents.
Organise scans into folders, then back up to your Google Drive — never our servers. Files land as ordinary PDFs you can open on any device. Foldio only ever sees the files it created, never the rest of your Drive.
Text recognition in 5 scripts: Latin, Chinese, Japanese, Korean, and Devanagari — all on-device, all automatic.
No data collected. No exceptions.
Camera access is handled entirely by Google ML Kit — Foldio never declares the camera permission. Documents are stored in app-private internal storage and deleted when you uninstall. Optional backup goes only to your own Google Drive — never a Foldio server. Full privacy policy →
Your documents belong to you — not to a server you're renting.
Most scanner apps keep your documents on their servers and charge a monthly subscription to get them back. Foldio works the other way around: it backs up to a folder in your own Google Drive, as standard PDFs.
