Upload without the quality hit

Stops the platform from re-encoding your video — in three test uploads, TikTok handed back the exact file we sent. Your picture and sound are copied byte for byte — nothing is re-encoded, nothing is uploaded anywhere. It all happens in this tab.

How to keep the quality on TikTok

This page is one step of four. The others matter just as much — a perfect file uploaded the wrong way still comes out soft.

  1. Finish the edit first

    Add your sound and trims in your editor, then change nothing in TikTok. We recommend exporting at 1080p, 60 fps.

    Why

    Trimming a clip or adding audio inside TikTok makes it re-encode the video, which throws away everything you are about to gain. Arrive with a finished file.

    1080p at 60 fps is the sweet spot: sharp on a phone screen, and smooth on the hardware most of your viewers actually have. 2K and 4K work too — TikTok accepts them, and here they survive intact instead of being downscaled — but they tend to stutter in the feed on ordinary phones, because the app is decoding your video while preloading the next ones.

  2. Run it through this page

    Drop the exported file in above and download the result. Nothing is uploaded anywhere, and not a single frame is re-encoded.

  3. Upload it the right way for your device

    This is where the rest of the quality is won or lost. Open yours:

    On a computer

    Easiest and most reliable. Go to tiktok.com and upload normally. Desktop web also accepts far larger files than either phone app does.

    On Android

    Upload through the browser rather than the app — the app compresses anything over about 72 MB before it sends it. Open tiktok.com, switch on Desktop site in the browser menu, and upload from there.

    On iPhone

    TikTok's web upload is unreliable here: even with Desktop site turned on, the upload screen appears and then hangs once you tap upload. Use a computer if you can reach one. If you cannot, a third-party posting tool does work — we used Postoria, and there is a short video walkthrough of that route. Tools like that need access to your TikTok account, so pick one you are comfortable handing that to.

  4. Check that it worked

    Once it is live, paste the link into the quality checker. If it comes back at the resolution you exported, the upload survived.
