Creafix · RCS Creative Validator & Preview

Validate RCS rich cards & carousels against Google RBM specs. Preview on a real phone, fix crops, and catch errors before launch.

Creafix is an RCS creative validator and previewer for marketing, design and campaign teams. Preview your RCS rich cards and carousels on a realistic phone, check them against the official RCS for Business specifications, and fix crops — before anything reaches your bot team or your customers. No more "the image got cropped on the phone", "the title was cut off" or "the file was rejected" after launch. Creafix shows you exactly how a creative will look and tells you what to fix. WHAT YOU CAN PREVIEW • Vertical rich cards — Short, Medium and Tall media heights • Horizontal rich cards — media on the left or right • Carousels — 2 to 10 cards, Small or Medium width, with the real truncation order simulated • Text messages with suggestion chips • Agent logo (224 × 224) and banner / hero image (1440 × 448) • Images and videos, on compact, regular and large phone screens WHAT IT CHECKS • Image and video file types (JPEG, PNG, GIF, MP4, WebM and more) • File size limits, including the 100 MiB per-message limit • Aspect ratios for every card height — with a preview of how the device will zoom and centre-crop off-ratio media • Title (200), description (2000), message (3072) and suggestion (25) character limits — emoji counted correctly • Number of suggested replies and actions per card and per message • Thumbnail size and ratio • Brand colour contrast Every result is clearly marked Pass, Warning or Fail, and labelled as an Official rule or a Team guideline. TEAM GUIDELINES Add your own team rules on top of the official specs — smaller file-size limits, safe margins for logos and text, and shorter recommended title and description lengths. Team guidelines raise warnings, never failures, and can be edited or turned off in Settings. FIX, DON'T JUST FLAG • Built-in cropper — crop any image to the exact required size and ratio, with padding if you need to zoom out • Video thumbnail generator — pick a frame and export a thumbnail under the recommended size • Safe-zone overlay — see what might get clipped by rounded corners SHARE WITH YOUR TEAM Export a phone preview snapshot, the fixed media file, or a validation report to send to your bot or campaign team. PRIVATE BY DESIGN • Your images, videos and text are processed entirely in your browser. They are never uploaded to any server. • No access to the websites you visit. • Anonymous usage analytics only if you opt in — never your creatives, file names or text. You can turn it off any time in Settings. • Recent sessions are saved only if you turn that on, and only on your device.
