How do I check the quality of a TikTok video?

Copy the video's link from the Share menu in TikTok, paste it into the checker above, and press Check. It reads the header of the video file TikTok serves and reports the resolution, frame rate, bitrate and codec.

Q: How can I tell if TikTok compressed my video?

Compare what you exported with what the checker reports. If you exported 1080p and the checker says 1080p, your upload survived. If it says 540p or 720p, TikTok re-encoded it on the way in.

Q: Does TikTok reduce video quality?

TikTok re-encodes every upload. Whether the result keeps your original resolution and bitrate depends on how the file was prepared before uploading.

Q: Can I check someone else's TikTok video?

Yes. Any public TikTok video can be checked. Private, deleted, age-restricted and region-locked videos cannot, because the link TikTok publishes for them does not resolve.

Paste a link to any public TikTok video and test what is actually being served — resolution, frame rate, bitrate and codec, read from the real file rather than guessed. Free, no signup, nothing to install.

What this tells you

TikTok re-encodes uploads. This reads the file it ends up serving, so the numbers here are what your audience actually receives — not what you exported.

If you uploaded 1080p and this says 1080p at a healthy bitrate, your upload survived. If you uploaded 1080p and this says 540p, it was re-encoded on the way in. That is the thing the tool on the home page exists to prevent.

Two limits worth knowing

It can only see what is there now, not what you sent. A 720p result means the delivered video is 720p — whether that is because you exported 720p or because TikTok reduced it is something only you know.

Public videos only. Private, deleted, age-restricted and region-locked videos cannot be read, because the link TikTok publishes for them does not resolve.

How to test your TikTok video quality

Copy the video link

In the TikTok app, tap Share then Copy link. On the web, the address bar works too. Both tiktok.com/@you/video/… and short vm.tiktok.com links are accepted.
Paste it above and press Check

Nothing is downloaded to your device. Only the first part of the file — the header that carries the technical details — is read.
Compare it with what you exported

The numbers describe the file TikTok delivers. Held against your export settings, they tell you whether the upload survived or was reduced.

Common questions

How can I tell if TikTok compressed my video?

Compare the two. If you exported 1080p and this reports 1080p at a healthy bitrate, your upload came through. If it reports 540p or 720p, it was re-encoded on the way in.

Does TikTok reduce video quality?

TikTok re-encodes every upload — that part is unavoidable. Whether the result keeps your resolution and bitrate depends on how the file was prepared beforehand, which is what the encoder on the home page handles.

What bitrate should I expect?

A 1080p vertical video usually lands somewhere between 2 and 6 Mbps. Much below that at 1080p means the picture was squeezed hard even though the frame size stayed large.

Can I check someone else's video?

Yes, as long as it is public. It is a reasonable way to see what quality actually reaches viewers on accounts that look sharp in your feed.
