File & Image Uploads

What Is a File Upload Form?

A file upload form is an online form with an upload field, so respondents can attach documents, images, or any other file directly to their answers. The files arrive with each submission, stored against that response, and you control which file types are allowed and how large each file can be. It replaces asking people to email attachments separately, which leaves you matching files to names by hand.

People search for this in a dozen ways - an upload form, an online form with file upload, a form builder with file upload, a form uploader, forms that allow file upload, or a form to upload files - and they all describe the same thing: one form where the answers and the attachments arrive together.

Image Upload Forms and Photo Upload Forms

Alongside the general file field, FormNX has a dedicated image upload field built for pictures. Use an image upload form when what you need is visual: photo contest entries, damage evidence on an insurance claim, ID or passport photos on a verification form, product shots from a supplier, or before-and-after pictures on a service report. You still control the accepted formats and the size allowed for each image, and respondents can send one picture or a set, depending on how you configure the field.

Document Upload Forms for Resumes, Invoices and Contracts

A document upload form is the same field pointed at paperwork. Restrict it to PDF and DOC and it becomes a resume collector on a job application form; point it at invoices and receipts and it becomes an expense submission form; pair it with an e-signature field and you can collect a signed contract and its supporting documents in a single step. Because each file is tied to its own submission, reviewing an application means opening one response rather than assembling it from an inbox.

How to Create an Upload Form Without Writing Code

Building the form takes about as long as describing it. In the drag-and-drop builder, drag a File Upload or Image Upload field onto your form, choose the formats you are willing to accept, set the maximum size for each file and how many files the field will take, then publish. Share it as a hosted link, embed it on your website, or open it as a popup. There is no backend to build, no storage bucket to configure, and no upload script to maintain - the field, the storage, and the delivery are all handled for you.

Your Respondents Never Sign In to Upload

This is the practical difference that decides most upload forms. Google Forms requires respondents to sign in to a Google account before they are allowed to attach a file, which quietly excludes anyone who does not use Google - and job applicants, clients and customers regularly do not. A FormNX upload form works for whoever has the link. No account, no login prompt, and no applications lost at a sign-in screen nobody expected.

File Types, File Counts and Per-File Size Limits

Every upload field carries three controls. Allowed file types restrict the field to the formats you actually want - PDF for paperwork, JPG and PNG for photos, MP4 for a short video clip, ZIP for artwork - so anything outside the list is rejected before the form submits. Maximum file size caps how large an individual file can be - and it is worth knowing that this limit applies to each file separately, not to the submission as a whole, so a field allowing five files at a 1MB limit accepts five files of 1MB each. File count sets how many files that one field will take, which is what separates a single-resume field from a multi-image portfolio field.

A Free Form Builder With File Upload Included

File and image uploads are part of the FormNX free plan, not a paid add-on, and they sit alongside unlimited forms and unlimited submissions. That matters because upload capability is exactly where several builders draw the paid line - Webflow gates its file upload element behind higher site plans, and Wix leaves it out of entry tiers altogether. If you need a free file upload form that real people can actually complete, you can build one, publish it, and start collecting documents without a card.
