File uploads & signatures
Collect files and drawn signatures. Formstep stores them with each submission.
File upload
Add File Upload from the Blocks tab, or type / and pick it. To set its rules, click the drag handle and open Validation:
| Rule | What it does |
|---|---|
| Min files | How many files the respondent must attach. |
| Max files | The most files allowed. Set it to 1 for a single file. |
| Max size (MB) | The largest size per file. A single file can never be larger than 1 GB. |
| Accepted types | Pick the file types you accept, such as PDF, Word, Excel, images, video, audio, or ZIP. Pick several to allow several. Leave it empty to accept any file. |
The question shows respondents these rules, such as “Max 5 MB”. Open a submission in the inbox to view or download its files. In logic, use has file and has no file.
Uploads count toward your storage
Every file, signatures included, counts toward the workspace owner's storage. When it is full, the form refuses uploads. Set a Max size if you collect large files. See Limits & quotas.
Signatures
A Signature question lets respondents draw a signature with a mouse or a finger. Formstep stores it as an image. In logic, use is signed and is not signed.
Respondents cannot change what they signed: a form with a signature does not allow edit after submit.
