Question details
The user fills out a fillable PDF form on an iPad using an Apple Pencil, but the filled information disappears or the form stops working when sent to a recipient via email.
- Product
- Device & OS
- iPad
- Scenario
- Filling out an interactive PDF form using an Apple Pencil and attempting to share the completed document via email.
- Observed behavior
- The completed form loses its filled data, appears blank, or breaks its functionality when the recipient attempts to open the emailed file.
Ensure that your iPad's PDF reader app is updated to the latest version, as older software can sometimes fail to correctly embed Apple Pencil annotations during the export process.
Save a Copy and Share the Flattened File
Save the filled form locally to embed the data, then use built-in share options to send a flattened copy that preserves the Apple Pencil inputs.
When you email a document directly without properly saving it, temporary Apple Pencil inputs and form data might not write to the permanent file structure. Saving the document locally and flattening it ensures the data becomes uneditable but perfectly visible to the recipient.
Once you finish filling out the PDF with your Apple Pencil, tap the 'Save As' or 'Save a Copy' button in your PDF app to save the document to your iPad's local storage.
Close the current document, then reopen the newly saved file to confirm that all handwritten and typed fields remain fully populated.
If the recipient only needs to read the form and not edit it, select the 'Flatten' or 'Print to PDF' option in your app. This merges your Apple Pencil inputs permanently into the document.
Instead of sending an unsaved temporary document, use the app's 'Share' or 'Send a Copy' option to attach the permanently saved PDF to your email.

Frequently Asked Questions
Why does my filled PDF show up completely blank when I email it?
This usually happens when the form data is treated as temporary memory and hasn't been permanently written into the document's structure before attaching it to an email. Saving a flattened copy to your local device first resolves this issue.
Can I use Apple Pencil to fill out standard text fields in a PDF?
Yes, using iPadOS's 'Scribble' feature or compatible applications like WPS Office, your handwritten Apple Pencil input can be automatically converted to standard typed text within fillable form fields.
What does it mean to 'flatten' a PDF document?
Flattening a PDF merges interactive elements, such as fillable text fields, signatures, and Apple Pencil drawings, into a single, permanent visual layer. This prevents further edits and ensures the file looks exactly the same on any device.
How can I be sure the recipient will see my filled data?
The safest method is to close the file on your iPad after saving it, then reopen it from your files app. If you can still see the data, it is saved. For maximum cross-platform compatibility, always send a flattened version of the PDF.
