Creatives
Creative size and safe-zone checker
Check dimensions, ratio, size and duration before uploading a creative batch. Use the preview to inspect cropping and your selected guide margins.
Choose files to check.
Crop and guide areas
After checking, select a file in the table for an approximate center-crop preview.
Hatched areas are your selected margins, not an official platform interface map. The files themselves are not cropped.
Files and text are processed on your device and are not sent to the blog server. Individual tool settings are saved only in this browser.
How to use it
- Add images or videos and choose a target aspect ratio.
- Set file-size and duration limits. Select a file to preview.
- Adjust the top and bottom guide margins. Download the check results as CSV.
Guide margins are configurable because platform interfaces change. This is an approximate crop preview and technical check, not approval or exact-rendering assurance. Codecs are not validated.
Questions and answers
Which files and upload limits are supported?
Up to 20 files and 150 MB in total. Each image can be up to 20 MB and 24 megapixels; each video up to 100 MB. Video reading depends on browser codec support.
Do the safe zones reproduce Meta or TikTok interfaces?
These are margins you configure, not an official platform template. Adjust the top and bottom for your placement. The preview approximates cropping without modifying the file.
What does “no findings” mean?
The file meets your selected technical conditions. Ad content, usage rights and offer eligibility are not evaluated. Check the codec and final in-platform rendering separately.
