Drag and drop any image or video file. We accept JPG, PNG, MP4, MOV, and GIF — up to 1 GB. No account required for your first check.
02 / ANALYSE
Instant spec check
We run 20+ checks across every major platform in parallel — dimensions, file size, aspect ratio, codec, color profile, text overlay density, safe zones, and more.
03 / FIX
Fix before it costs you
Get a clear pass/fail verdict per platform with actionable fixes. Know exactly what to change so your creative clears review on the first submit.
20+ preflight checks,
every time.
Each creative is validated against the latest platform specs. We catch what you can’t see before the ad manager rejects it.
Color Mode
Detects CMYK, sRGB, P3 and other color profiles that can cause washed-out or shifted colors on different ad platforms.
Dimensions & Aspect Ratio
Validates pixel dimensions and aspect ratios against each platform's required specs so your creative isn't cropped or letterboxed.
File Size
Checks file size limits for each platform and format, flagging assets that will be rejected at upload.
Text Overlay %
Estimates the percentage of your image covered by text, helping you stay within platform guidelines for maximum delivery.
Safe Zones
Overlays platform UI elements like CTAs, profile icons, and captions to ensure nothing critical is hidden.
Video Length & Codec
Validates video duration, codec, frame rate, and bitrate against each platform's specifications.
The spec mistake you don’t find until after launch.
- ✕CMYK color profile slipped through and your Meta ads looked washed out for three days.
- ✕TikTok safe zone cut off your headline because nobody checked the overlay.
- ✕Wrong aspect ratio got uploaded to Stories and the creative was cropped to nothing.
- ✕Text overlay hit 28% and Meta throttled delivery without telling you why.

Trusted by performance
marketers who hate surprises.
“We caught a CMYK file that would have tanked an entire Meta campaign. AdPreflight paid for itself on the first upload.”
“I used to manually cross-reference every spec doc before uploading. Now I drag, drop, and know in seconds. Total game-changer for freelancers.”
“Our team ships 40+ creatives a week across four platforms. AdPreflight is the only thing stopping us from launching broken ads.”
