Fill and Sign PDF Forms for Android

Fill and Sign any PDF form containing AcroFields.

Form fields are extracted from the document and presented in a simple user interface for easy access and filling. For that purpose form fields should have been labeled correctly by the form creator. In case they are not, real-time split-screen mode might be of some help, but it depends on the size of your device’s screen (see the screenshots). Full-screen read-only form preview is also available.

Signature capture capability depends on external Signature Capture library. You will be prompted for installation once when needed.

Except filling and signing, it is possible to attach photos to documents. Input data can be exported and produced documents can be viewed, mailed and shared by different means.

Input PDF documents can be opened directly from your device’s file manager or they can be accessed via app’s built in file browser.

Output documents in demo/trial mode are watermarked and the app contains ads.

Full app version has no ads and allows you to save documents without a watermark. It also allows you to export your input data to csv or json and to access the app’s API (for 3rd party app integration). Read more about integration with a third party android app.

This is an outstanding product for form usage on android devices. It allows for even the most complex of forms to be made easy to use. The interface is very clean and the signature capture is perfect. I needed some support for an additional feature and it was a great experience. Excellent tech support. I highly recommend this app to anyone.

This product is very good and useful for android tablet users. You have to know how to create fields informs to use it. […] I can fill out contracts and get them signed on my tablet and never have to print!

It is a good app for android devices which just got better. You can have your pdf docs signed. You need to first prepare your pdf doc from Adobe or programatically to allow input. I have used Fill and Sign on Google Android tablets and now on 11 Samsung Galaxy tablets without any issues. Solid App. […]

Frequently asked questions


It’s possible that the fonts you are using are not supported by either our application or the PDF reader installed on your Android device. Please try opening the filled form on your PC. If the data is still not displayed, email the original PDF Form to the support email address and we will investigate the issue.

Yes, there is a limited JavaScript support. If something isn’t working with your form, please send it to our support email here and we’ll take a look.

Your PDF form must include a signature field, plain text fields do not qualify. If you have a signature field, a button will appear that initiates the signature capture process.

If you need a tool to create fillable PDF forms, Adobe Acrobat, Microsoft Office and free Open/Libre Office provide that functionality.

By default, photos are not appended as separate pages, but attached to your PDF form. You can change that behavior in app settings. Regarding photos that are attached, if you open your PDF form in Adobe Reader for example, you will notice a paperclip icon next to the document page. Clicking on this icon will list your attached photos.

Press the Menu button, then select Settings. Under the Output section, you will find a Read only option. Set it to either Ask or Never.

Yes, there is. The order of fields follows the TAB order defined in your form.
