# Fix TikTok Video Quality

> TikTok video low quality after upload usually comes from TikTok's own recompression: it re-encodes every video and squeezes harder when 'Allow high-quality uploads' is off, Data Saver is on or the file doesn't match its preferred 1080 × 1920 format. Turn on high-quality uploads, export 1080p H.264, and upscale low-res clips to 1080p before posting.

## Steps
1. Check the source — If the clip is below 1080p or was re-saved from another app, upscale it first.
2. Upscale to 1080p on Kenerate — Upload the MP4, MOV or WebM and keep 1080p; a 9:16 clip comes back at about 1080 × 1920.
3. Keep the export TikTok-friendly — If you edit further, export H.264 MP4 at 1080 × 1920, 30 or 60 fps.
4. Turn on Allow high-quality uploads — On the posting screen, under More options.
5. Turn off Data Saver — In TikTok's settings, so uploads and playback aren't reduced.
6. Upload on a stable connection — Wi-Fi beats patchy mobile data for a full-quality upload.

## In depth

### Every upload is re-encoded
TikTok recompresses all uploads to balance file size against clarity [1]. A file that was already compressed — saved from another app, or exported at a low bitrate — loses detail twice, the generation loss you see as blur and blocks [3].

### The settings that matter
Clipchamp's guide lists the main culprits: Data Saver on, high-quality uploads off, a slow connection, and recording in HDR instead of SDR [1]. It recommends 1080 × 1920, H.264, 30 or 60 fps at roughly 8–15 Mbps, and advises against 4K, which is downscaled to about 1080p [1].

### Where an upscaler helps
If the source is 480p, 720p or a re-saved copy, no setting can add the missing detail. Upscaling to 1080p with Kenerate rebuilds sharper frames and removes existing blocking, so TikTok's encoder starts from a clean, full-size file.

## FAQ
Q: Why is my TikTok video quality bad?
A: TikTok's quality drops when its re-encoding has to work hard: 'Allow high-quality uploads' is off, Data Saver is on, the file is 4K or an unusual size, or the clip was already compressed by another app. A slow or unstable connection while uploading can lower the quality too.

Q: How do I upload high quality video to TikTok?
A: Export a 1080 × 1920 H.264 MP4 at 30 or 60 fps, turn on 'Allow high-quality uploads' under More options on the posting screen, turn off Data Saver and upload on stable Wi-Fi. If the original is below 1080p, upscale it to 1080p first.

Q: Should I upload 4K to TikTok?
A: No. TikTok plays video at about 1080p, so a 4K upload gets downscaled and recompressed, which can add blur. Upscale or export to 1080p instead — on Kenerate, a 9:16 clip at 1080p comes out at about 1080 × 1920.

Q: Can I fix a TikTok video that's already posted?
A: Not in place, because TikTok keeps its compressed copy. Go back to your original file — not a download from TikTok, which is already compressed — upscale it to 1080p if needed, and post it again with the high-quality setting turned on.

Q: Does upscaling help if my clip is only 720p?
A: Yes. A 720p clip uploaded to TikTok is stretched and then compressed. Upscaling it to 1080p first with Kenerate's AI Video Upscaler gives TikTok a sharper, full-size file and removes existing compression blocks, while the length and frame rate stay the same.

Q: Why does my video look bad on X (Twitter)?
A: X re-encodes uploads too. Its developer guidance recommends H.264 at 1280 × 720 landscape or 720 × 1280 portrait, at 30–60 fps. Upscale soft clips to 720p or 1080p before posting, and upload your original file rather than a re-download.

Q: Will the upscaler crop my vertical video?
A: No. Sizes are a pixel budget, so a 9:16 TikTok stays 9:16: at 1080p it comes back at about 1080 × 1920, with no bars and no cropping. The length and frame rate are unchanged too, so the file is ready to post as soon as you download it.
