How to Compress Video for TikTok Upload (2026 Guide)

TikTok has become the go-to platform for short-form video content, but uploading videos is not always smooth. Many creators run into the "file too large" error, especially when working with high-resolution footage from cameras or screen recordings. Here is everything you need to know about getting your videos upload-ready for TikTok.

TikTok File Size Limits

TikTok allows uploads up to 287MB on most modern devices. However, older phones may be limited to 72MB. Videos can be up to 10 minutes long. For ad uploads through TikTok Ads Manager, the limit is 500MB.

If your video exceeds these limits, you will need to compress it before uploading.

Best Video Settings for TikTok

TikTok recommends these specifications: Resolution of 1080x1920 pixels (9:16 vertical), MP4 or MOV format, H.264 codec, frame rate of 30fps or 60fps, and file size under 287MB. The vertical 9:16 format is critical because TikTok displays content full-screen on phones.

How to Compress Videos for TikTok

Use NowTo Tools' video compressor to reduce your video file size. The tool works directly in your browser with no file upload to any server, keeping your content private before posting.

Steps: 1. Open the tool. 2. Upload your video. 3. Set target size to under 287MB. 4. Keep resolution at 1080x1920 for best quality. 5. Click Compress and download.

Why Does TikTok Reject My Video?

Common rejection reasons include: file exceeds size limit, unsupported format (use MP4), corrupt file header, or aspect ratio issues. If you are shooting in landscape, consider cropping to 9:16 for TikTok.

Quality Tips for TikTok Creators

TikTok re-encodes all uploaded videos regardless of quality. Starting with a high-quality source (1080p) gives TikTok's encoder the best material to work with. Avoid compressing too aggressively — medium quality at 1080p resolution is the sweet spot.

Lighting matters more than resolution on TikTok. A well-lit 720p video looks better than a dark 4K video after TikTok's compression.
