This guide shows how to change the allowed file types on your form when using the File Upload element.
The default allowed files extensions are as follows:
- DOC
- DOCX
- XLS
- XLSX
- CSV
- TXT
- RTF
- HTML
- ZIP
- MP3
- WMA
- MPG
- FLV
- AVI
- JPG
- JPEG
- PNG
- GIF
You can add or remove these extensions to limit your form only to accept specific file types. Here’s how:
- In Form Builder, add a File Upload element to your form or select an existing one.


- Select the File Upload’s gear icon to open properties.

- In the properties pane on the right, go to Options at the top.
- List your allowed file extensions comma-separated in the File Types field.


Notes:
- The allowed extensions list is case-insensitive.
- List the extensions without a leading dot (e.g., enter “pdf” instead of “.pdf”).
- Enter asterisk (“*”) in File Types to allow all file types.
- Your form will show an invalid extension message when a form filler tries to upload a file that is not in the allowed list.

Hello,
I work for a community center and was wondering which package would be best. We have about 20 pages of forms, some that require signatures which is why we are upgrading from google forms. We enroll about 50 people a month. Would the 25 per month package suffice?
Thank you in advance.
Best,
Wendy Parker

Hi, I have my settings to email me a report of the submission with the file uploads. When they are jpegs the images are included in the emailed pdf, but when they are pdfs they are not included in the emailed report. it is just a link to the pdf. is there a way to get the emailed report to include and image of the pdf, or append the pdf to the emailed pdf. i hope that makes sense.

thx!
Thats big, you guys are the best free form builders.
thats massive!
Indeed the best!
Jotform is the best form creator !
Yeah, we noticed that too. They implemented our form in their own lightbox mechanism, so the form didnt fit properly. Unfortunately,
it was out of our hands at that point.
go Jotform!!
This is excellent. Now we're playing in the "Big Leagues"!
Just one minor problem I noticed when the form loaded:
Go Jotform! That'll give the service some great exposure.
You can allow all types of files simply by putting * in the box.
When I upload a file (PDF or doc)through browse button to my website & hit submit button I get email with all the fields on my form,but I cannot open doc file. When I click on it it shows zip file which I save on my hard drive & try to open it, it shows only xml files but no doc file. How can I get orignal file uploaded through form in my email.
Is there a maximum number of file types allowed?
