👋 Hey Hunters! I’m Filip, the maker of CheckSafe.Zone. If you work in digital marketing, media buying, or content creation, you know the pain of the "Revision Ping-Pong." 🏓 You get a great 9:16 video from the design team, upload it to TikTok or Reels, and boom—the CTA is covered by the caption, and the logo is hidden behind the like button. Or, you get an HTML5 banner archive, try to upload it to Google Ads, and it's rejected because it's 152KB or missing a clickTag. I built CheckSafe.Zone to stop this madness. I wanted a fast, no-BS tool that I could just keep in my bookmarks to check assets in 2 seconds before sending them to the client or pushing them live. ✨ Key Features: Video Safe Zones: Exact 2026 UI overlays for TikTok, IG Reels, YT Shorts, Snapchat, and TV Broadcast, as well as Social Media static posts. HTML5 Validator: Drop a .zip file and instantly check dimensions, exact file weight, and clickTag presence. 100% Private & Local: This was crucial for me when handling embargoed agency campaigns. Your files never leave your device. The magic happens entirely in your browser. The tool is completely free. I’d love for you to drop a video or a banner, play around with it, and let me know your thoughts! What platform or format should I add next? Cheers! 🚀
