Tinyforms allows you to receive any file uploads with your form. We will securely store the file for you and link it in your spreadsheet.
You actually don't have to do anything. Just make sure your HTML form has the
enctype="multipart/form-data" set and use a
input type="file" field.
<form **enctype="multipart/form-data"** method="POST" action="..."> <input type="file" name="attachment"> <button type="submit">Submit</button> </form>
