How to Insert Photos and Signatures in PDF Forms on Android & iPhone
Question details
The user needs to fill PDF form fields with photos and signatures using a mobile device.
- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- Android and iPhone
- Scenario
- Filling out an interactive PDF form created in Adobe Acrobat Pro DC while using a mobile phone.
- Observed behavior
- The mobile app does not accept or process the photo and signature fields as expected when tapped.
Ensure your mobile PDF application is updated to the latest version, and save a backup copy of your original blank PDF form before making edits on your phone.
Use the Fill & Sign Tool in Acrobat Reader Mobile
Bypass unresponsive interactive form fields by manually overlaying your signature and photos using the Fill & Sign feature.
Advanced interactive fields (like image upload boxes) created in Acrobat Pro DC sometimes do not function natively on free mobile reader apps. Instead of clicking the field directly, you can use the Fill & Sign tools as a manual workaround.
Launch the Adobe Acrobat Reader app on your Android or iPhone and open the PDF document you need to fill.
Tap the blue pencil icon at the bottom right of the screen and select 'Fill & Sign' from the menu.
Tap the fountain pen icon on the bottom toolbar, select 'Create Signature', and choose to draw your signature or upload an existing signature image from your gallery.
Tap anywhere on the document to place the signature, then drag it over the designated form field and resize it as needed.
Complete the Form Using Desktop PDF Software
Open the file on a PC or Mac to fully utilize the interactive form fields designed in Acrobat Pro.
Easily Add Signatures and Photos to PDFs with WPS Office
WPS Office provides powerful mobile PDF editing capabilities. Whether you need to sign forms or insert images onto your documents, the WPS mobile app allows you to bypass unresponsive fields and easily complete your tasks on both Android and iOS devices.
- 1. Install WPS Office: Download and install WPS Office from the Google Play Store or Apple App Store, then open your PDF file.
- 2. Access PDF Tools: Tap 'Tools' at the bottom of the screen and navigate to the 'PDF Edit' or 'Annotation' tab depending on your needs.
- 3. Insert your signature: Select 'Signature' to create and insert a hand-drawn signature, or upload a pre-saved signature image.
- 4. Add a photo: To add a photo, select the 'Add Image' tool, choose a photo from your phone's gallery, and drag it over the required form field.
- 5. Save changes: Tap 'Done' at the top left to apply your edits, then tap the save icon to store your completed PDF document.
Frequently Asked Questions
Why are PDF form fields unresponsive on my iPhone or Android?
Advanced form fields, especially those containing custom JavaScript or strict digital certificate requirements created in Acrobat Pro DC, are often unsupported by basic or free mobile PDF readers. You may need to use manual annotation tools to overlay your content.
Can I add a digital certificate signature on mobile?
Most standard mobile apps only support electronic signatures (drawn with a finger or uploaded as an image). True cryptographic digital signatures generally require specialized secure mobile applications or full desktop PDF software.
How do I convert a photo to a PDF on my phone?
You can use the WPS Office mobile app. Simply open the app, tap 'Tools', and select 'Picture to PDF'. This feature allows you to select images from your gallery and instantly convert them into a single, standard PDF document.
