The 8 Best Creative Proofing and Approval Tools in 2026

Key takeaways

• Ziflow is the best proofing tool for most ad teams. It reviews more than 1,200 file types, including HTML5 banners and live websites, runs approval stages in sequence or in parallel, and lets unlimited reviewers comment for free, from $199 a month billed annually.

• PageProof has the most AI on every plan. AI-suggested markup comes with its flat $249-a-month Team plan, and reviewers don't need an account.

• Filestage is the most generous with seats. Its free plan includes 10 seats, and Enterprise adds a password-verified approval for regulated teams.

• ReviewStudio is the cheapest per seat. It costs $12 a user a month billed annually and handles HTML, video, audio, and live web pages.

• Catch changes before the ad platform does. Meta and TikTok re-review an edited ad, so a late fix can cost another day.

Why approvals slow ad teams down

A 2025 study by BetterBriefs with the IPA and WFA, which surveyed more than 1,000 agency, marketer, and in-house professionals in 54 countries, found that it typically took five rounds of creative development to reach a signed-off idea. Earlier IPA research in the UK had put it at three. Only 30% of agencies and 52% of marketers agreed they gave clear and constructive feedback.

The ad platforms add their own step. Meta's Advertising Standards say ad review "is typically completed within 24 hours," and an edited ad is treated as a new one and reviewed again. TikTok's ad review FAQ says the same: most ads are reviewed within 24 hours, and editing an ad's creative triggers another review.

Proofing tools replace email threads and screenshots with comments pinned to the exact spot on an image, the exact frame of a video, or the exact element of a banner. Each version sits next to the last, each stage has a deadline and a named approver, and the record of who signed off on what stays with the file. Every change made inside the proofing tool is one you don't have to make after the ad is live.

How we ranked

We ranked on the range of ad formats each tool can review (statics, video with time-coded comments, HTML5 and display ads, live web pages, PDFs), how well it handles multi-stage approvals with deadlines and decision rules, whether outside reviewers can comment without an account, audit trails and compliance features, published pricing, and the size of each tool's G2 review base.

The eight tools compared

1. Ziflow - Best overall

Ziflow is an online proofing platform built around unlimited proofs and unlimited reviewers.

What works: The free plan already reviews more than 1,200 file types, and Ziflow handles the ad formats that trip up simpler tools: full-motion HTML5 banners, rich media combined into one proof, and live websites at any resolution. Video and audio take comments down to the second, with safe-zone overlays for 1:1, 4:3, 9:16, and 16:9. Pixel-level comparison shows what changed between versions. Approval stages run in sequence or in parallel, with deadlines, a rule that only one decision is needed, and the option to skip stages already approved on an earlier version. Reviewers don't need a license on any plan. Standard is $199 a month billed annually for 15 users, and G2 reviewers rate it 4.5 out of 5 from 948 reviews.

What doesn't: Its most useful extras, including ReviewAI checklists, automatic deadline reminders, and unlimited stages, are on Enterprise. Standard allows two stages.

Best for: Agencies and in-house ad teams that review banners, video, and landing pages in one place.

2. PageProof - Best for AI checks and flat pricing

PageProof is a proofing platform that includes its AI tools on every plan.

What works: It reviews static files, video, audio, web banners, zipped HTML, HTML emails, and live and staging websites, with smart and side-by-side comparison between versions. PageProof Intelligence suggests markup on a proof, and Enterprise agents check work against brand guidelines, legal disclaimers, and accessibility standards. A Content Credentials check shows how a file was made, including any AI involvement, and PageProof says your data isn't used to train public models. Reviewers open proofs from an email link with no account, and workflows and templates are unlimited. Team is a flat $249 a month or $2,499 a year with unlimited storage, and G2 reviewers rate it 4.8 out of 5 from 391 reviews.

What doesn't: There's no free plan, and trials are by request. G2 reviewers say the lack of folders can make large accounts messy.

Best for: Teams that want AI checks and predictable pricing without counting seats.

3. Filestage - Best for agencies with many client reviewers

Filestage is a review and approval tool that groups reviewers into stages.

What works: It handles video, images, designs, documents, websites, interactive HTML, and audio, with frame-accurate comments on video and side-by-side version comparison. Reviewer groups act as approval stages, with due dates and automatic reminders, and reviewers can comment without creating an account. The Business plan adds overlay and text comparison, automations, and Review Agents that check grammar, tone, QR codes, and barcodes before anyone reviews. Enterprise turns the approve button into "Approve and sign," with password verification for FDA 21 CFR Part 11 and EU Annex 11. The free plan includes 10 seats, Starter is $199 a month, and there's a 14-day trial with no card. G2 reviewers rate it 4.6 out of 5 from 247 reviews.

What doesn't: The free plan allows one active project and five new files a month, and the AI agents and automations start on the $329 Business plan.

Best for: Agencies that send work to many client reviewers and want them organized by stage.

4. StreamWork - Best for routing through legal, brand, and leadership

StreamWork is an online proofing tool for enterprise marketing teams, agencies, and in-house studios.

What works: It routes creative through stages in sequence, such as legal, brand, and leadership, with automated deadline reminders and nudges. You can set a primary decision maker for each stage and decide when a stage counts as complete. Video gets frame-accurate and range comments, audio gets time-stamped ones, and layered design files are supported. Any stakeholder can review and approve from a single link, with unlimited free reviewers. There's a free plan for two users, Starter is $169 a month billed annually ($219 monthly) for 15 users, and the 14-day trial needs no card. G2 reviewers rate it 4.7 out of 5 from 55 reviews.

What doesn't: Starter allows one approval stage, and StreamWork documents no HTML5 banner or live website review.

Best for: Brand and enterprise teams whose ads need sign-off from several departments in order.

5. ReviewStudio - Best for small teams on a per-seat budget

ReviewStudio is a proofing tool priced per user with unlimited guests.

What works: It covers video (including ProRes), HTML as a ZIP or URL, live web pages, audio, images and PSDs, documents, and even 3D and 360-degree images, with version comparison on every plan. Every plan supports multiple approvers, reminders, and batch approvals, and guests can be set as approvers without accounts. Pro is $12 a user a month billed annually ($15 monthly), a free Starter plan has unlimited users and three active reviews, and the 30-day trial needs no card. G2 reviewers rate it 4.7 out of 5 from 157 reviews.

What doesn't: Custom stages, conditional workflows, and automations need the Advanced plan, which has a five-seat minimum, and Pro caps active reviews at 10 per user.

Best for: Small creative teams that review many formats and want to pay only for the seats they use.

6. Approval Studio - Best for static and print-led ad work

Approval Studio is a proofing tool with strong roots in packaging and print.

What works: It reviews more than 23 file formats, including PDFs, design files, and HTML, plus MP4 video and snapshots of live web pages, with four comparison modes. Projects move through custom Kanban stages, and you can add a disclaimer to the approve button. External reviewers don't need to register. An optional AI compliance report checks an asset against a reference document and grades each requirement as met, partial, or missed. Lite is $60 a month for five users, and the 14-day trial needs no card. G2 reviewers rate it 4.8 out of 5 from 44 reviews.

What doesn't: Video review is limited to MP4, the AI tools and workflow automation cost extra, and Lite and Pro include 5GB of storage.

Best for: Teams producing static ads, retail displays, and print alongside digital work.

7. Wipster - Best for video-only teams

Wipster is a review tool built for video, with support for audio, PDFs, and images.

What works: Reviewers leave time-coded comments on video, and version comparison shows what changed between cuts. Comments can be public or private to your team, and captions and variable playback speed help reviewers on longer cuts. Projects, reviews, and reviewers are unlimited, and clients don't need to sign up. Team is $19.95 a user a month billed annually ($25 monthly) with no user limit, and the free trial needs no card. G2 reviewers rate it 4.7 out of 5 from 50 reviews.

What doesn't: Wipster documents no multi-stage approval routing and no HTML5 or live web review.

Best for: Video teams and editors who need fast client feedback on cuts.

8. Pastel - Best for landing pages and live websites

Pastel is a feedback tool built first for live websites.

What works: You share a live site, a landing page, an ad, a PDF, or a video, and reviewers comment directly on it without an account. A responsive tester checks layouts at different screen sizes, and you can set feedback deadlines and reminders, assign comments, label them, and record approvals. Versions are unlimited, so you can jump between them to see what changed. There's a free plan, Pro is $29 a month billed annually ($35 monthly) for two users, and the 14-day trial needs no card.

What doesn't: It has no approval stages or audit features beyond a CSV export, and G2 lists only 14 reviews.

Best for: Performance teams reviewing landing pages that sit behind their ads.

Frequently asked questions

What is a creative proofing tool?

It's software where reviewers comment directly on an image, a video frame, a PDF page, a banner, or a live web page, and where each version and each approval is recorded in one place. It replaces feedback scattered across email, chat, and screenshots.

Do clients need an account to review proofs?

Not in any tool on this list. Ziflow, PageProof, Filestage, StreamWork, ReviewStudio, Approval Studio, Wipster, and Pastel all let outside reviewers comment from a link without a paid seat.

Which proofing tools can review HTML5 banner ads?

Ziflow reviews full-motion HTML5 banners and rich media, PageProof reviews web banners and zipped HTML, ReviewStudio takes HTML as a ZIP or URL, and Filestage reviews interactive HTML.

Which proofing tools support 21 CFR Part 11?

Filestage offers password-verified approvals for FDA 21 CFR Part 11 on its Enterprise plan. For pharma and other regulated advertising, specialist platforms such as Aproove build every plan around Part 11 e-signatures and an immutable audit trail, from $12,000 a year.

How much do proofing tools cost?

Ziflow, Filestage, StreamWork, ReviewStudio, and Pastel all have free plans. ReviewStudio costs $12 a user a month and Wipster $19.95, both billed annually. Team plans start at $60 a month for Approval Studio, $169 for StreamWork, $199 for Ziflow and Filestage, and $249 for PageProof.

How long does ad review take on Meta and TikTok?

Both say most ads are reviewed within 24 hours, though some take longer. Editing an ad's creative sends it back through review on both platforms, so final changes are best made before the ad is submitted.
