How it works

Your documents, sorted before you ask.

Let it look

Allow access once and Sunfolio finds every PDF, Word, text and image file on your phone. Prefer to pick folders yourself? That works too.

Find it fast

Files are grouped by type, with Recent and Favorites. Search names without typing accents, sort by name, date or size.

Read, or get it done

Open a large PDF in under a second and pick up where you stopped. Or turn to the PDF tools: scan, merge, split, compress.

A comfortable reader

Easy on the eyes, day or night.

  • Smooth scrolling and pinch to zoom, vertically or page by page
  • Search the text, jump to a page, follow the table of contents
  • Light, Sepia and Night reading modes
  • Opens password-protected PDFs and remembers your page
  • Word (.docx) in a clean reading view; text files of any size; photos with zoom

Free PDF tools

Eight tools. No upload, no watermark.

Every tool runs on your phone and saves a new file in Download/Sunfolio. Your original stays exactly as it was.

Paper to a clean PDF: edges found, filters for crisp text.

Images to PDF

Good to know

What this first version doesn't do yet.

Word files show in a reading viewSo the layout can differ from the original. Older .doc files open with another app.
Excel and PowerPoint open with another appSunfolio lists them so you can find them, and hands them to a viewer you have.
Scanning needs Google Play servicesThe scanner is Google's, run by Play services on your phone. Sunfolio itself has no camera permission.
No signing, notes or text recognition yetThose come later. This version is about reading well and the eight tools above.

Questions

Asked before you ask.

Is Sunfolio free?

Yes. This version is free, with no ads and no in-app purchases. Every PDF tool is free too.

Why does it ask for access to all files?

So it can find every document on your phone and list it for you; Android only gives document files from other apps to apps with this access. You can say no: Sunfolio then works with the folders and files you pick.

Are my files uploaded anywhere?

No. Reading and every tool happen on your phone. The only things sent are anonymous crash reports and usage counts, without names or content.

Does a tool change my original file?

Never. Each tool saves a new file in Download/Sunfolio, so your original stays as it was.

Which Android versions are supported?

Android 8.0 and newer.
