On iPhone and iPad, the reliable path is Files app to Safari to Files app: locate the source, complete one focused PDF task, download a new copy and verify it before sharing.

Organize the source in Files

Save email or message attachments into a known Files folder first. Rename the source clearly and keep it unchanged. If iCloud shows a cloud icon, wait for the document to download before opening a browser tool. For HEIC photos, use HEIC to PDF or convert a reviewed image copy.

Edit with touch controls

Use PDF Editor for text, highlighting and a visible typed or drawn signature. Pinch to zoom before placing small elements. An Apple Pencil on iPad improves precision, but always inspect the flattened download; the preview is not the final file.

Build a PDF from the camera

  1. Photograph pages in even light with all corners visible.
  2. Crop and rotate each image.
  3. Use Scan to PDF or JPG to PDF.
  4. Arrange pages in reading order.
  5. Choose A4 when a portal expects standard print pages.
  6. Open the downloaded PDF from Files.

Find the downloaded file

Safari normally shows a download arrow near the address bar. Open it, choose the file, then use Share or Move to place it in the correct Files folder. If the browser appears to do nothing, check Settings for the configured Safari download location and confirm the site is allowed to download.

Know when to switch devices

Use a desktop for long contracts, many annotations, side-by-side comparison or very large scans. A phone is strong for capture, quick signing and simple conversion; a larger screen is safer when page-level review matters.

Frequently asked questions

Can I combine iPhone photos into one PDF?

Yes. Use HEIC to PDF for original iPhone photos or JPG to PDF after exporting images as JPG.

Is a drawn signature a digital certificate?

No. It is a visible image signature, not a certificate-backed digital signature.
