How it works
How to use it
Choose a video
Your browser reads the length, size and resolution. Nothing is uploaded.
See every platform
Each platform shows Good to go, Check or Won't post, with the reason.
Fix it before posting
Trim, compress or reframe before posting, so nothing fails halfway.
Tips
- Vertical 9:16 at 1080×1920 works on TikTok, Reels, Shorts, Threads and Pinterest.
- Facebook Reels max out at 90 seconds. Longer videos can still go out as regular video posts.
- YouTube accounts that aren't verified can upload up to 15 minutes.
- Keep files under 300 MB if you post to Bluesky and Instagram Reels.

FAQ
Common questions
Is my video uploaded?
No. Your browser reads the video's details on your device. Nothing is sent to us.
Can it check frame rate and codec?
Not reliably. Browsers don't share them. Most platforms want 23 to 60 frames per second and H.264 video in an MP4 or MOV file.
Why do some limits look different from what the app allows?
These are the limits for posting through each platform's official tools, which is how scheduling apps post. Some apps allow more when you upload by hand.
Why does X say up to 20 minutes?
That's what X's developer docs allow for standard accounts. X's help center lists lower numbers for uploads in the app.
What does Check mean?
It will probably post, but something needs a look, like a size the platform may scale down.
