Why Adobe Fill and Sign Increases PDF File Size on Android & How to Fix It
Question details
The user wants to know why signing a small PDF document using the Adobe Fill and Sign app on an Android tablet results in a significantly larger file size.
- Product
- Adobe Fill and Sign
- Device & OS
- Android
- Scenario
- Filling and signing a PDF document on an Android tablet.
- Observed behavior
- The output PDF file size increases significantly compared to the original small PDF.
Before troubleshooting, check the exact file sizes of both the original and signed PDFs to confirm the size difference, and ensure your Adobe Fill and Sign app is updated to the latest version on your Android device.
Report the File Size Issue to Adobe Support
Since this is a known technical behavior requiring investigation from the developers, sending the before and after files to Adobe's support team is the official recommendation.
Adobe relies on user-submitted files to investigate and fix bugs related to unexpected file bloating during the signing process.
Locate your original, unsigned PDF document and the resulting large PDF saved by the Adobe Fill and Sign app.
Note your exact Android device model, the Android OS version running on your tablet, and the version number of the Adobe Fill and Sign app you are using.
Write an email describing the exact steps you took to fill and sign the document, and attach both the before and after PDF files.
Email the details and attached files to fillandsign_support@adobe.com so the development team can investigate the file size increase.
Compress the Signed PDF to Reduce File Size
If you need an immediate workaround to send or upload the file, you can compress the bloated PDF using a dedicated PDF editor or online tool.
Use WPS Office to Fill, Sign, and Compress PDFs
Avoid unexpected file size increases by using WPS Office. Our integrated PDF editor allows you to seamlessly fill forms, add digital signatures, and export documents while maintaining an optimized file size.
- 1. Install WPS Office: Download and open WPS Office on your Android device or PC.
- 2. Open your PDF: Open your original, unsigned PDF document using the WPS PDF viewer.
- 3. Fill and Sign: Tap on the 'Fill & Sign' or 'Annotation' tools on the bottom menu to add your text and signature seamlessly.
- 4. Save and Compress: Save the document. If you want to make it even smaller, use the 'Compress' tool under the PDF tools menu to securely reduce the file size before sharing.
Frequently Asked Questions
Why do PDF files get bigger when I sign them on a tablet?
Adding a digital signature or using fill and sign tools can embed additional font data, high-resolution stroke images from your signature, or complex graphical layers into the document, which exponentially increases the overall file size if the app does not optimize the output.
How can I prevent Adobe Fill and Sign from increasing my file size?
Currently, there is no direct setting within the Adobe Fill and Sign app to prevent this bloating. Users are advised to manually compress the PDF after saving or report the issue to Adobe support with the source files for a permanent fix.
Can I compress a signed PDF directly on my Android tablet?
Yes, you can use third-party applications like WPS Office or various online PDF compressor tools directly from your tablet's web browser to reduce the file size of the signed document.
Is Adobe Fill and Sign the only way to sign PDFs on Android?
No, there are several alternative apps available on the Google Play Store, such as WPS Office, which offer robust PDF viewing, form filling, and signing features with much better built-in file size management.
