It checks an ad creative against thousands of placements from Facebook, Instagram, TikTok and other publishers.\n\nA user drops in an image, video, audio file or HTML5 zip, then picks a placement and a preview device. The tool compares the file with the placement's requirements for size, format, safe zones and copy limits. Each check shows the measured value, the required value and whether it passes.\n\nThe tool can also check a VAST tag by fetching the tag and its wrappers in the browser. Where an ad server blocks that request, the user can paste the XML instead. Results can be exported to PDF.\n\nFiles stay in the browser and are not uploaded. Visitors get three free checks per day, and signing in with an email address raises the limit to 50 checks per day.","categories":["ai"],"features":["Checks files against more than 4,000 ad placements","Supports image, video, audio and HTML5 creatives","Shows safe zones for each preview device","Checks VAST tags and their wrappers in the browser","Exports results to PDF"],"pricing_model":"freemium","pricing_summary":null,"cta_label":null,"screenshot_url":"https://screenshots.azn8.com/screenshots/448d5055-800b-4a97-a878-239f52847848/412b6f463dd4199d.webp","screenshot_status":"ready","screenshot_updated_at":"2026-11-09T08:39:30.571Z","status":"live","source":"human","url":"https://azn8.com/listing/all-ad-specs-ad-specs-tester","created_at":"2026-11-09T08:39:22.448Z","updated_at":"2026-11-09T08:39:22.448Z","published_at":"2026-11-09T08:39:22.448Z","featured":false}}
