Nothing kills momentum like an upload error at 11 p.m. You finished the edit, hit post, and TikTok rejects the file - Too long, too big, or the wrong format. Knowing the actual numbers saves you from re-exporting three times and guessing.

TikTok's limits also shift depending on where you upload from. The mobile app and the web uploader have different file size caps, and some regions get longer maximum durations than others. On top of that, TikTok compresses everything you upload, so the version viewers see is never the version you exported.

This guide lays out the 2026 numbers in one place: length limits, size caps, resolution, formats, and the bitrates that hold up best after compression - Plus why your original export deserves a backup.

Key takeaways

  • Standard uploads run up to 10 minutes, with 30- and 60-minute uploads tested in some regions and account tiers.
  • File caps differ by source: about 287 MB from the mobile app versus up to 2 GB from the web uploader - Big file, use the browser.
  • Export 1080 x 1920 (9:16) MP4 with H.264 at 8-12 Mbps; TikTok recompresses everything to roughly 1-2 Mbps.
  • Completion rate peaks around 21-34 seconds, so save the long formats for tutorials and storytimes.

How Long Can a TikTok Video Be?

TikTok started at 15 seconds. In 2026, the ceiling is much higher:

  • Standard uploads: up to 10 minutes for most accounts.
  • Extended uploads: TikTok has tested 30-minute and even 60-minute uploads in some regions and account tiers. If you don't see the option, your account doesn't have it yet - There's no setting to force it.
  • Photo-mode and Stories: shorter caps apply, and Stories disappear after 24 hours.

Longer doesn't mean better, though. TikTok's own data and most creator analytics point to a sweet spot of 21-34 seconds for completion rate on short-form content. Save the long formats for tutorials and storytimes where watch time is the goal.

File Size Caps: Mobile vs. Web

This is where most upload failures happen. The cap depends on how you upload:

  • Mobile app (iOS/Android): around 287 MB on iOS and 72-287 MB on Android, depending on app version and region.
  • Web uploader (tiktok.com): up to 2 GB.

So if your 10-minute 1080p edit weighs 850 MB, the phone app will refuse it - But the web uploader takes it without complaint. That's the single most useful trick in this guide: big file, use the browser.

Note: The web uploader's 2 GB ceiling is roughly 7 times the mobile cap. If the app keeps rejecting a long edit, the fix is almost always to upload from tiktok.com in a browser rather than trimming the video down.

To upload from your computer, you first need the file off your phone or out of your editor. If your export lives on your phone, a quick way to bridge the gap is a transfer link - ShareIt.onl lets you upload up to 10 files or 200 MB from your phone with no sign-up, then open the expiring link on your computer and download the exact same file, byte for byte. For files above 200 MB, split the project or see how to send large files for more options.

Resolution, Aspect Ratio, and Formats

The spec that matters most: 9:16 at 1080x1920

TikTok is a vertical platform. Export at 1080x1920 pixels (9:16) and your video fills the screen edge to edge. Other ratios technically work - 1:1 and 16:9 get letterboxed with bars or a blurred background - But full-screen vertical consistently outperforms them.

Accepted formats

  • MP4 (H.264) - The safe default, recommended by TikTok.
  • MOV - Fine, especially from iPhones; TikTok converts it.
  • WebM and a few others are accepted on web, but MP4 avoids surprises.

Keep frame rate at 30 or 60 fps, and use AAC audio at 128-192 kbps. Avoid variable frame rate (common in screen recordings) - It can cause audio drift.

Full Specs Table (2026)

Spec Recommended Hard limit / notes
Length 21-34 sec for reach; longer for tutorials 10 min standard; up to 60 min in some regions
File size Under 287 MB for mobile upload ~287 MB mobile / 2 GB web (varies)
Resolution 1080x1920 (9:16 vertical) Minimum 720p recommended
Format MP4 (H.264 + AAC) MOV also accepted
Frame rate 30 or 60 fps, constant VFR can desync audio
Video bitrate 8-12 Mbps at 1080p Higher helps little after compression
Audio AAC, 128-192 kbps, 44.1 kHz -

How TikTok Compresses Your Video (and How to Fight It)

Whatever you upload, TikTok re-encodes it to stream efficiently - Typically down to roughly 1-2 Mbps for most viewers. That's why crisp exports sometimes look soft in the feed. You can't skip compression, but you can feed it a better source:

  1. Export at 8-12 Mbps, 1080x1920. A clean, high-bitrate source survives re-encoding far better than an already-compressed one.
  2. Turn on "Upload HD" in the post screen's quality settings so TikTok serves a higher-bitrate stream where available.
  3. Avoid double compression. Don't run your export through a messaging app or an extra "compress video" step before uploading.
  4. Watch fine detail and fast motion. Confetti, rain, and quick pans are hardest to encode; slightly slower cuts and good lighting keep them cleaner.

One thing that never fixes quality: third-party "HD downloader" or re-upload tools. Beyond being useless for quality (the compression already happened), using third-party downloaders on content you don't own violates TikTok's Terms of Service and usually copyright. This guide sticks to official methods and your own files.

Keep Your Originals - The Uploaded Copy Is Not a Backup

Because TikTok compresses everything, your uploaded video is a lossy copy the moment it goes live. If your phone dies or the app gets deleted, that watermarked 1-2 Mbps stream may be all that's left. Two habits prevent that:

  • Archive every export. Keep the clean MP4 from your editor. If you only have the posted version, learn what you can still recover in how to download your own TikTok videos, and protect unposted work with a drafts backup routine.
  • Share originals, not screen recordings. When a collaborator needs your clip, send the source file with an expiring link instead of letting an app recompress it. Our guide to the best way to share large videos compares the options; a 150 MB master transfers in one shot on ShareIt.onl with a link and QR code, and the link expires so it isn't floating around forever.

FAQ

What is the maximum file size for a TikTok upload?
About 287 MB when uploading from the mobile app (less on some Android builds) and up to 2 GB from the web uploader at tiktok.com. If your file is too big for the app, upload from a browser instead - The limit is roughly 7 times higher.
What resolution and bitrate should I export for TikTok?
Export 1080x1920 (9:16 vertical) MP4 with H.264 video at 8-12 Mbps, constant 30 or 60 fps, and AAC audio at 128-192 kbps. TikTok will compress it to around 1-2 Mbps for streaming, and a high-quality source survives that squeeze much better than a low-bitrate one.
Why does my video look blurry after uploading?
TikTok re-encodes every upload to a lower bitrate for fast streaming, and weak sources degrade the most. Export at a high bitrate, enable "Upload HD" before posting, and never send the file through a messaging app first - That adds a second round of compression before TikTok's.
Can I use a downloader tool to get a higher-quality copy of a TikTok?
No. Downloaded copies come from the compressed stream, so there's no hidden HD version to grab - And third-party downloaders violate TikTok's Terms of Service and usually copyright when the content isn't yours. The only full-quality copy is the original export, which is why backing it up matters.
