File Upload Block

Published July 25, 2026

Use a File Upload block when participants need to attach supporting documents or images before they complete a quiz. It is useful for intake files, resumes, screenshots, reference images, application materials, and proof documents that belong with the submission.

Participant-facing File Upload block showing upload instructions, accepted PDF, JPG, and PNG file types, 10 MB file size limit, and navigation buttons.

The participant sees your prompt, upload instructions, supported file types, file-size guidance, and the upload button in the quiz flow.

Best used for

Client intake documents

Collect briefs, forms, references, or supporting documents before a consultation.

Resumes and applications

Ask applicants to attach a resume, portfolio sample, or related document.

Photos and screenshots

Let participants upload visual proof, examples, before photos, or product screenshots.

Review materials

Capture PDFs or images that help your team prepare before follow-up.

When to choose another block

Need a written explanation

Use a Text Response when the participant can describe the detail instead of attaching a file.

Need contact details

Use Lead Capture for name, email, phone, company, and appointment-related fields.

Need a date

Use Date Picker when the important input is timing rather than a document.

Need structured qualification

Use Choice Buttons or Multiple Choice when the next path depends on a clean answer.

Setup flow

  1. Add a File Upload block from the Question Blocks palette.
  2. Write a prompt that names exactly what the participant should upload.
  3. Turn on Required response only when the file is necessary to continue.
  4. Set Max files between 1 and 5 based on how many attachments you expect for this block.
  5. Use Split Media if the quiz uses a Full-Page Split layout and this question needs its own visual context.
  6. Add Jump Logic if upload completion or later follow-up answers should change the participant's path.

Settings reference

Plan access

Accepted files and limits

Accepted file types

File size

Each file must be 10 MB or smaller.

Files per block

Each File Upload block can accept 1-5 files.

Files per submission

A submission can include up to 10 total uploaded files across upload blocks.

Uploaded files are attached to the submission so owners can review the file alongside the participant's answers. Keep prompts specific so participants know what file to choose and why it matters.

Prompt guidance

Strong upload prompts reduce support issues and rejected files.

  • Name the exact file you need, such as "Upload your resume" or "Attach a screenshot of the issue."
  • Mention supported formats when the file type matters.
  • Explain whether one file is enough or whether multiple supporting images are expected.
  • Avoid asking for sensitive information unless it is necessary for the workflow.
  • Do not make the upload required unless the next step truly depends on the file.

Routing guidance

File Upload blocks are usually best for evidence or context, not scoring. If the uploaded file should change the next path, use Jump Logic around clear upload conditions or collect a structured follow-up answer after the upload.

For example, a participant can upload supporting materials, then answer a Choice Buttons question about the document type. That structured answer can route the quiz more reliably than trying to infer meaning from the file itself.

Troubleshooting

Why was a file rejected?
The file must be a PDF, JPG, or PNG and must be 10 MB or smaller. Files outside those formats or size limits are blocked.
Why can I not add a File Upload block?
File Upload is not part of the current public launch package. Existing authorized configurations are preserved, but new public use is not granted by plan.
Why can participants not add another file?
Check the block's Max files setting. Each File Upload block supports 1-5 files, and each submission supports up to 10 total uploaded files.
Should I make file upload required?
Make it required only when the file is essential. Optional uploads are better when the file adds context but should not block completion.

Tips

  • Keep upload questions near the point where the file becomes relevant.
  • Use one File Upload block per distinct file request so submissions stay easy to review.
  • Ask for screenshots or photos only when visual proof matters.
  • Pair uploads with structured questions when you need reliable segmentation or routing.
  • Test with a valid PDF, JPG, and PNG before publishing.
  • Test a file larger than 10 MB so you know what the participant sees when a file is rejected.
