Bluesky Upload File Size Limit 2026 (100MB)

Bluesky caps individual video uploads at 100MB per file, and separately limits every account to roughly 25 videos or 10GB of total video uploads per day, whichever comes first. Images are limited much lower, at roughly 1MB each, so the video ceiling only applies once you attach an actual video file rather than a photo or graphic.

Per video limit: 100MB

A single video post cannot exceed 100MB. Since Bluesky videos also cap out at 3 minutes long, most well compressed clips at 1080p land comfortably under that ceiling. Where creators run into trouble is uploading straight off a phone camera at its highest bitrate setting, which can produce files well over 100MB for even a one minute clip.

If your export is coming in too large, the fix is almost always bitrate, not resolution: dropping from a high bitrate 4K or 1080p export to a standard web bitrate 1080p export usually cuts file size dramatically with no visible quality loss on a phone screen.

The daily account ceiling: 25 videos or 10GB

This is the limit that catches accounts off guard, especially anyone running a bot, a scheduling backlog, or bulk uploading a backlog of old content. Once your account hits 25 video uploads or 10GB combined in a day, whichever limit you reach first, further video uploads get blocked until the next day. A single account posting a handful of videos a day for a content calendar will never come close to this, but a batch upload session trying to backfill a month of video content in one sitting absolutely can.

Quick reference

Limit	Value
Max file size per video	100MB
Max video length	3 minutes
Daily account video ceiling	25 videos or 10GB combined
Max images per post	4 (video and images cannot combine)

Compressing a video without losing quality

Most video editing apps and even phone camera settings default to a bitrate far higher than a mobile viewer will ever notice. Before assuming you need to cut your video shorter to hit 100MB, try exporting at a standard web bitrate for 1080p (roughly 5 to 8 Mbps) instead of your device's maximum setting. That single change routinely cuts file size by half or more with no visible difference once the video is compressed further for playback on a phone screen, which is the only place most Bluesky video actually gets watched.

Working around the limits

If you regularly hit the daily ceiling, spread bulk video uploads across two or three days rather than one, and compress before uploading rather than relying on Bluesky's own processing. For day to day scheduling, these limits are generous enough that a normal posting cadence of a few videos a day will never trigger them.
