Online Proofing Software for Client Approvals
Flatproof helps small studios proof websites, PDFs, images, videos, Figma work, and presentations with one review link, visual comments, versions, and approvals.
Proof, review, and approve creative work without the usual feedback chase.
Online proofing is the category. Review is the action. Flatproof gives clients a simple place to look at the work, leave visual feedback, and approve the latest version.
Website proofing
Collect website feedback on live pages and keep comments with the project instead of losing them in email.
PDF and presentation proofing
Review decks, documents, and client-ready PDFs with comments attached to the right proof.
Image proofing
Pin clear comments on layouts, ads, social graphics, mockups, and visual assets.
Video proofing
Keep time-based video comments beside the version and approval state.
Why studios switch
A focused proofing workflow instead of another broad portal.
Flatproof is built for the common small-studio job: send work, gather clear feedback, ship a new version, and get approval.
No client onboarding tax
Clients can open a proof link and comment without becoming another paid seat. That matters when every project has a slightly different reviewer list.
Flat reviewer economics
Invite creators, clients, stakeholders, and approvers without turning the proofing workflow into a seat spreadsheet.
