Check your Meta ad before you upload it.
One pass instead of three tools: drop your ad image to see Meta's safe zones drawn over it and a size/ratio verdict, then paste your copy for live character counts and a "See more" truncation preview. Runs entirely in your browser - your image never leaves your device.
Safe zones, ratio and resolution
JPG, PNG or WebP. Story/Reels images get the 14% top / 35% bottom / 6% sides overlay; every image gets a ratio and resolution verdict against Meta's current recommendations.
Character counts and the See-more fold
Counts compare against Meta's published recommendations per field; the preview shows roughly where Feed truncates primary text (Meta publishes no exact threshold).
Limits mirror the Meta ad spec cheat sheet, verified against Meta's Ads Guide. Adhook's paid pipeline runs checks like these automatically on every creative it generates.
Preflight, answered
What does the preflight check cover?
Everything worth catching before Ads Manager sees the ad: the safe-zone overlay on Story/Reels images, an aspect-ratio and resolution verdict for the closest placement, and live character counts with the See-more preview for your copy.
Is my ad image uploaded anywhere?
No. The image is read and drawn on a canvas in your own browser - it never leaves your device, and there is nothing to sign up for.
When should I use the specialist tools instead?
This page is the one-pass bundle. For deeper single jobs use the story safe-zone checker (downloadable design overlays), the character counter (per-field truncation preview) or the mockup generator (your creative inside real Feed and Story frames).
Can I generate ads that pass these checks automatically?
Yes - every creative Adhook generates is composed with the safe zones respected and ships with copy already inside Meta's limits. Try it with 10 free credits, no card.
