Discord video/file uploads Video Specs: Limits, Formats

Key Discord Video Upload Specs (2026)

Discord’s current file upload limits are 20 MB for free users, 50 MB with Nitro Basic, and 500 MB with Nitro. There is no official duration limit - your video just needs to fit the file size cap. MP4 and MOV files (H.264, HEVC/H.265, AV1 codecs) play inline, while other formats may require download. Discord does not publish official limits for aspect ratio or resolution, but most standard video sizes work. Captions are not supported, so you must burn them into your video before uploading.

How to Export Clips That Fit Discord’s Limits

Keep file size under the cap: For free users, compress your video to under 20 MB. Shorter clips and lower resolutions help.
Use supported formats: Export as MP4 (H.264 is safest). MOV is also supported. Avoid uncommon codecs.
Resolution and aspect ratio: Discord doesn’t enforce specific values. Vertical, square, and widescreen videos all upload, but test playback if using unusual formats.
Burn in captions: Add subtitles directly into the video, since Discord won’t show separate caption files.

Tips for Creating Discord-Ready Clips

Trim long videos: Since file size is the main limit, shorter clips are easier to fit under the cap.
Compress wisely: Use export settings like 720p or 480p for longer clips to reduce file size without losing too much quality.
Check before uploading: On Android, Discord checks file size before compression, so pre-compress your videos.
Watch for NSFW scanning: Discord may block uploads it flags as unsafe.

Using Vidulk to Export Clips for Discord

Vidulk’s AI Clipper (iOS and Android) helps you find and export the best moments from long videos, podcasts, or livestreams.
