Video & Image Specs Checker
A reference chart for the major platforms, plus a checker that reads your actual file's width, height, duration and size — entirely in your browser — and compares them against whichever placement you pick.
Platforms change these numbers often, and they vary further by app version and account type (Premium/Business tiers especially). Treat this as a fast sanity check, not the final word — always confirm against the platform's own current help page before a big upload. Last checked against public sources in September 2026.
Choose a placement and a file to see the comparison.
Reference chart
Recommended specs by placement. "Min resolution" is the lowest that avoids obvious quality loss, not the platform's hard floor.
How to use the Video & Image Specs
- Choose the placement you are uploading to.
- Select your video or image file. It is read on your device, not uploaded.
- Fix anything marked with a warning before you post.
