Compressing video to exactly 300 MB is a common need for TikTok uploads (287MB limit), longer social media content, and video portfolios. Whether you're trying to fit a video into a platform's upload limit or simply want to reduce storage usage, hitting a precise file size target requires smart encoding — not just lowering quality across the board.
300 MB is a significant target because platforms like TikTok (≈287MB) enforce this as their maximum upload size. Exceeding this limit means your video gets rejected — there's no partial upload or automatic compression. You need to compress your video to 300 MB or less before uploading.
The amount of video you can fit into 300 MB depends heavily on resolution, framerate, and content complexity. Fast-moving content (gaming, sports, action) requires more data per second than static content (presentations, screencasts, talking heads). At 720p with moderate motion, expect roughly 10m of video. At 1080p, that drops to about 5m.
SquishVideo uses a two-pass encoding approach with H.264. First, we analyze your video's complexity frame by frame. Then we allocate bitrate intelligently — giving more data to complex scenes and less to simple ones. This means you get the maximum possible quality within your 300 MB target. The result is a standard MP4 file that plays everywhere — browsers, phones, tablets, desktop players, and every social media platform.
| Resolution | Low motion | Medium motion | High motion |
|---|---|---|---|
| 480p | 40m | 20m | 13m 20s |
| 720p | 20m | 10m | 6m 40s |
| 1080p | 10m | 5m | 3m 20s |
| 4K | 2m 40s | 1m 36s | 1m |
The following platforms have a file size limit near 300 MB: TikTok (≈287MB). Compressing your video to this size ensures it uploads without errors.
TikTok's actual limit is ~287MB — compressing to 300MB gets you close with margin. Always start with the highest quality source possible — compressing an already-compressed video results in worse quality than compressing the original. If your source video is significantly larger than 500MB, consider trimming it first.
With 300 MB to work with, 1080p is the recommended resolution for most content. You have enough bitrate to maintain sharp, artifact-free video. For 4K source material, consider whether 4K output is necessary — 1080p at higher bitrate often looks better than 4K at constrained bitrate.
Audio typically uses 128-192 kbps in the compressed file. While that's a small fraction of the total, for very small target sizes like 300 MB, it matters. SquishVideo optimizes audio compression automatically, using AAC encoding at the right bitrate to maintain clear audio without wasting space.
