Folio: Doc Maker

Scan or import
Scan with your camera with automatic edge detection, or import photos from your gallery. You can even share photos to Folio from WhatsApp or any app.

Fix it fast
Auto-crop and straighten pages, rotate, reorder, duplicate or delete pages. Make text clearer with Auto, Grayscale or B&W modes.

Fit any size limit
Need a PDF under 100 KB, 200 KB or 1 MB for an exam, job or government form? Pick the limit and Folio does the rest. Export as PDF or JPG images.
