How to Compress a PDF on iPad — Free, No App Needed
The iPad's large screen makes it a natural for working with PDFs — reading, annotating, signing. But when you need to reduce a PDF's file size to email it or upload it to a portal, there's no built-in compression tool in iPadOS. ShrinkPDF runs in Safari and solves this without any App Store download.
Step-by-Step: Compress PDF on iPad
Open Safari on Your iPad
Tap Safari and go to shrinkpdf.fyi. The site adapts to the iPad's larger screen — you'll see the full layout rather than the mobile compact view.
Tap "Choose PDF File"
Tap the upload button. iPadOS will open the Files picker. You can browse On My iPad (local storage), iCloud Drive, or any connected cloud service like Google Drive or Dropbox if you have their apps installed.
Navigate to Your PDF
Browse to the folder where your PDF is stored. If you received the PDF via email, it may be in your Mail app — open it in Mail first, tap the attachment, then tap Share → Save to Files to move it to a Files folder. Then come back to ShrinkPDF and select it.
Choose Compression Level
Select Balanced for presentations, reports, or documents with images. Select Maximum for scanned documents, forms, or when you need the smallest file size.
Download the Compressed PDF
Tap Download. On iPad, the download indicator appears in the Safari toolbar (top right, looks like an arrow pointing down). Tap it to see the download. Tap the file to open it in Quick Look, or tap Open in Files to save it to your Files app.
After compressing, open the PDF in the Files app on your iPad and review it at full screen. The iPad's large display makes it easy to spot any quality issues at 100% zoom before you send the document. Pinch to zoom on any images or small text to verify readability.
Using Split Screen on iPad
One of the iPad's most useful features for this workflow is Split View — run ShrinkPDF in Safari on one side and your Files app (or Mail) on the other:
- Open Safari with ShrinkPDF loaded
- Swipe up from the bottom to show the Dock
- Long-press the Files app icon and drag it to the right side of the screen
- Now you can see both ShrinkPDF and your Files app simultaneously — drag the PDF from Files directly into the ShrinkPDF upload area
This is especially useful when working with several documents — you can see your file list on one side and the compression tool on the other without switching between apps.
Compressing PDFs in iCloud Drive
If your PDF is in iCloud Drive and hasn't been downloaded to the iPad yet:
- Open the Files app → iCloud Drive
- Find the PDF — if it shows a cloud icon, tap it to download to the iPad first
- Once the cloud icon disappears (file is local), go to Safari → ShrinkPDF
- Tap Choose PDF File → iCloud Drive → select the file
- Compress and download — the result saves to On My iPad → Downloads
Sharing After Compressing
- Email via Mail: Open Mail → compose → paperclip → select the compressed PDF from Files → send.
- AirDrop to Mac: In Files, long-press the compressed PDF → Share → AirDrop → select your Mac.
- Upload to a portal in Safari: Go to the portal in Safari → tap the upload field → Files → Downloads → select the compressed PDF.
- WhatsApp: Open WhatsApp on iPad → chat → paperclip → Document → select the compressed PDF from Files.
- Save back to iCloud Drive: In Files → Downloads, long-press the compressed PDF → Move → iCloud Drive → choose a folder.
