Editing PDFs on your iPhone or iPad doesn't have to be a hassle. PDFrust works directly in the Safari browser — no app to download, no account needed.

How does PDFrust work on iPhone?

Open Safari on your iPhone and go to pdfrust.com. Choose your desired tool (merge, split, compress…). Tap "Choose file" to upload a PDF from your Files app or iCloud Drive. All processing happens in your browser.

Save the PDF to your iPhone

After editing, tap the download button. Safari will open the file automatically. Tap the share icon (square with upward arrow) and choose "Save to Files" to store the PDF on your iPhone.

Tip: add to home screen

Use PDFrust regularly? Open pdfrust.com in Safari, tap the share icon, and choose "Add to Home Screen". This gives you a PDFrust app icon on your iPhone — without downloading anything.

Compress PDFs for WhatsApp

WhatsApp has a 100 MB file size limit. Is your PDF too large? Use PDFrust's compress tool to reduce the file size before sending.
