Questions people ask

How do I edit a PDF on my iPhone?

Open the PDF in Sheaf, choose Edit PDF, and tap any line of text to change it. You can also add text, images, drawings, highlights, shapes and your signature, then save.

Are my files uploaded to a server?

No. Every tool runs on your iPhone. Files are never uploaded, and the app works offline.

Is Sheaf free?

Yes. All basic tools are free to use and preview. You can save 3 files a day for free by watching one short ad each, on files up to 15 pages or 10 MB. After that it’s $0.99 per file, or Pro removes ads and limits. Free files are never watermarked.

Can I convert Word, Excel or photos to PDF on iPhone?

Yes. Import Word, Excel, PowerPoint, Pages, text or image files and Sheaf converts them to PDF on your device, ready to edit.

How do I merge PDFs on iPhone?

Choose Merge, add two or more PDFs, drag them into order and tap Merge. It happens on your iPhone in seconds.

Can I permanently remove sensitive information from a PDF?

Yes, with Redact (Pro). It removes the marked content from the file itself, not just hides it, and strips document metadata. Editing text only changes what’s shown on the page, so use Redact for anything confidential.
