Download and post
Export as MP4 at 1080×1920. If the file is still over 4GB or the clip runs past 15 minutes, use Compress Video or Trim Video first.
Built for anyone posting to Instagram Reels
Whether you manage Instagram content professionally or post the occasional clip — PixelTools crops your video to spec entirely in your browser, with no upload and no account.
Repurposing landscape footage
A clip filmed in 16:9 for YouTube gets center-cropped by Instagram's algorithm when posted as-is, often cutting off the subject. Cropping to 9:16 first lets you choose what stays in frame instead of leaving it to Instagram's auto-crop.
Trimming a screen recording
Screen recordings for app-demo Reels frequently run past 15 minutes and land well over 4GB at full resolution. Trimming to the relevant segment and compressing before upload avoids Instagram's upload rejection.
Batch-prepping a week of Reels
Social media managers cropping several clips to the same 1080×1920 frame in one sitting can do it without opening a desktop editor for each one.
Frequently asked questions
What is the correct Instagram Reel size?
+
1080×1920 pixels at a 9:16 aspect ratio. That's the same vertical frame Instagram uses for Stories, so a Reel and a Story export from the same crop.
What is the maximum length for an Instagram Reel?
+
Up to 15 minutes when uploaded from your camera roll. If you record directly in the Instagram app instead of uploading a file, the in-app camera caps you at 3 minutes.
What's the maximum file size for an Instagram Reel?
+
4GB. Most phone-shot clips land well under that, but a long screen recording or a 4K export can exceed it — compress before uploading if yours does.
What video format does Instagram accept for Reels?
+
MP4 or MOV, with H.264 video and AAC audio. That's what most phones and editing apps export by default, so format is rarely the blocker — aspect ratio and file size usually are.
Will Instagram crop my Reel if it isn't 9:16?
+
Yes. A landscape or square clip gets center-cropped to fit the 9:16 frame, which can cut off subjects near the left or right edge. Crop to 9:16 yourself first so you control what stays in frame.
Does Instagram compress Reels after upload?
+
Yes, all uploaded video is re-encoded. Uploading at exactly 1080×1920 minimizes the quality loss from that second compression pass — uploading a much larger file doesn't buy you extra sharpness.
