Frequently asked questions
- Is Scanto free to use?
- Yes. Scanto is completely free, with no watermark and no daily limit on the number of pages you can scan.
- Do I need to create an account or install an app?
- No. Scanto works directly in your browser — no sign-up and no installation required. You can optionally add it to your home screen for an app-like experience.
- Are my scanned documents uploaded to your servers?
- No. All image processing — perspective correction, filters, and PDF creation — happens entirely on your device. Your files are never sent to any server.
- What image formats can I convert to PDF?
- Scanto supports JPG, PNG, WebP, BMP, GIF, and HEIC/HEIF (the format used by iPhone photos).
- Can I scan multiple pages into a single PDF?
- Yes. Add as many photos as you need, reorder them by dragging, and export them all as one multi-page PDF.
- How do I scan a document using my phone's camera?
- Tap "Add page," allow camera access, and photograph the document. Drag the four corner handles onto the page's edges, and Scanto will straighten and enhance it for you.
- Does Scanto automatically crop and straighten my document?
- Scanto currently uses a fast manual corner-adjustment step — you drag four handles onto the page's edges — and then corrects the perspective so the page looks flat. Fully automatic edge detection is planned for a future update.
- Can I reorder or delete pages before exporting?
- Yes. You can drag pages to reorder them, rotate individual pages, or remove any page before generating the final PDF.
- Will there be a watermark on my PDF?
- No. Scanto never adds a watermark to your exported files.
- Does Scanto work on iPhone (Safari)?
- Yes. Scanto works in modern mobile browsers, including Safari on iPhone and Chrome on Android.
- Can I convert HEIC photos from my iPhone directly to PDF?
- Yes. Scanto automatically detects and converts HEIC/HEIF photos before processing, so you don't need to convert them manually first.
- Is there a limit on file size or number of pages?
- Scanto doesn't impose an artificial limit, though very large scans depend on your device's available memory.
- Can I use Scanto offline?
- Yes, after your first visit. Scanto can be installed as a Progressive Web App and continues to work without an internet connection.
- How is Scanto different from CamScanner or Adobe Scan?
- Scanto runs entirely in your browser with no install and no account, and never uploads your images to a server — while CamScanner and Adobe Scan are native apps that process or store scans through their cloud services.
- Does Scanto support OCR (searchable text)?
- Not yet in the current version — it's planned for a future update. Today, Scanto focuses on fast, private, high-quality image-to-PDF scanning.
