TikTok Upload File Size Limit 2026

The tiktok video file size limit isn't a single number, it moves depending on which device or method you're uploading from. That's a moving target worth checking each time TikTok updates its app, since the numbers below reflect what's commonly reported as of mid-2026 rather than a figure TikTok publishes as a fixed permanent spec.

TikTok max upload size by method

Upload method	Approximate limit
TikTok app (Android)	~72MB
TikTok app (iOS)	~288MB
Web uploader (tiktok.com)	Up to 4GB
TikTok ads (TopView format)	500MB

The gap between Android and iOS app limits is the detail most people miss, the same video that uploads fine from an iPhone can bump into a ceiling on Android well before reaching TikTok's more generous web-based allowance.

Why the tiktok video file size limit mb varies so much by device

TikTok's in-app upload path is tuned for how each mobile OS handles video compression and background processing, which is why Android and iOS numbers diverge instead of matching. The web uploader skips that mobile constraint entirely, which is why it accepts files many times larger, useful for longer, higher-resolution videos that would choke a phone-based upload.

Staying comfortably under the limit

• Compress before uploading from mobile, especially on Android, where the ceiling is tightest. A video shot in 4K on a modern phone can easily exceed 72MB before any editing.
• Use the web uploader for longer or higher-quality videos. If you're uploading a video close to TikTok's 60-minute length ceiling, the web path is the only realistic option given the size that duration typically produces.
• Export at 1080p rather than 4K for most content. TikTok compresses on its end regardless, so a smaller, well-compressed 1080p source often looks just as good in-feed as an oversized 4K file.

A habit that avoids the problem entirely

Exporting straight from your phone's camera roll at its default (often 4K) setting is the most common way people hit the Android app's tighter ceiling without realizing it. Dropping the export resolution to 1080p before uploading, either in your camera settings or during a quick edit pass, keeps most videos comfortably under the mobile app limits without any visible quality loss on a phone screen.

What happens if a file is too large

Rather than a clear error every time, an oversized upload can stall, fail partway, or get rejected outright depending on the app and connection. None of those are pleasant to discover mid-upload when you're trying to hit a specific posting time, which is the practical argument for compressing ahead of time rather than finding the ceiling by accident.

Keeping file size in check across platforms

If the same video is going to TikTok, Reels, and Shorts, sizing and compressing it once for the tightest limit in that group avoids uploading three different exports. The social media image resizer handles the dimension side of that conversion.
