This question type allows respondents to upload files. You may restrict the file types and size, and also allow respondents to use the Markup and the Crop features with the uploaded files.

Allowed File Formats

Use of the CMYK Color Model

Please note that the images uploaded via this type of question cannot use the CMYK color model; other color models (such as RGB) should be used instead.

For more information on the issue, feel free to contact our Support Team.

  • The delete button removes the answer choice from the question in the Standard or Rich text mode. A greyed-out button means that you are not allowed to delete this answer option because you have responses associated with it.

File Upload Settings

File Upload Settings can be applied for all questions of this type by going to Edit Form/Survey page-> Settings-> File Upload Settings tab, or by applying individual question settings on the Edit Question page.

Individual question settings prevail over the general File Upload Settings for all questions. 

First, select whether any file types should be accepted, or only specific ones:

If specific file types should be accepted, define the type of files respondents can upload:


Images (.jpeg, .jpg, .gif, .png, .bmp)
Specify whether it is allowed to upload the files from gallery and use Markup/Crop tool on the uploaded images:

Insert from Gallery option will appear only if response is submitted via our Mobile or Desktop Offline application.
Image gallery is the only source of the files for the devices with OS version lower than v4.4.4(for Android) and  v9.0(for iOS). For the devices with OS version newer than  v4.4.4(for Android) and  v9.0(for iOS) it is allowed to use any source, including gallery, Dropbox, Google drive, etc.

Select the size of the uploaded images:

          • Small (900 pixels by largest side)
          • Medium (1440 pixels)
          • Large (1800 pixels)
          • Keep original image size (the file will be re-sized keeping original dimensions). 

            Original dimensions of the image will be kept, however, due to security reasons, an overhead will be removed which might cause the size reduction, but not the quality.

          • Specify the max. side dimension (From 300px up to 7000px).

Set uploaded images view:

          • Small
          • Medium
          • Large (will show images one below the other). 

Date and Time Stamp for Photos:
Activate this option if you would like to see when the photo was taken. Date and Time Stamp can be displayed for photos taken via the Offline Mobile App. Images chosen from the Photo Gallery will not be date/time stamped.The Date and Time will appear on the photos once they are uploaded to the server. You may choose from one of the options below:

        • No Date/Time Stamp (default)
        • Date only YY.MM.DD
        • Date and Time YYYY.MM.DD HH.MM.SS

          If the Date and Time option is chosen, it will be recorded in the following format: YYYY.MM.DD HH:MM:SS in the device local time. The Time Zone will also be indicated. 


Documents (.doc, .docx, .xls, .xlsx, .xlsm, .ppt, .pptx, .csv, .txt, .pdf, .rtf, .xml)
Set the maximum size limit of the uploaded documents. The maximum size is 100 Mb (this value can not be changed). 

Other file types 

Specify extensions or MIME types of files to be allowed for uploading. It is preferred to identify the allowed file types by their extensions, however, in some cases using MIME types may be more convenient. For example, if you want respondents to upload any audio file, you may use audio/* MIME type to specify this. Be aware that the support for MIME types in some browsers may be incomplete. Please test the specification of the file format as MIME type for the files your respondents should upload in browsers they might be using.
Set the maximum size limit of the uploaded files. The maximum size is 100 Mb (this value can not be changed).
