We built this because Instagram's own upload tool is, well, not great.
Here you can resize your videos for Instagram Reels, Stories, and Feed posts — for free, right in
your browser. If it's a different shape / aspect ratio, you don't need to worry about cropping out important content — our tool lets you keep the whole video and use blur or color padding to fill the remaining space.
Oh, and it's super easy to use — you just upload your video, pick a preset, then press the big, pink "Resize Video" button (hard to miss). The algorithm works its magic on your video, and your Instagram-ready video will be ripe for the picking (well, downloading) after a few short moments.
How to Resize a Video for Instagram
- Upload your video — Click "Select Video" or drag and drop your file. We support MP4,
MOV, and AVI.
- Pick an Instagram preset — Choose the format you're posting to:
- Reels (9:16) — Full-screen vertical video
- Stories (9:16) — Same as Reels
- Feed Portrait (3:4) — The new ratio as of early 2026 (fills the whole screen in the viewer's feed)
- Feed Square (1:1) — Classic Instagram format
- Feed Landscape (1.91:1) — Widescreen
- Custom — Enter any width and height you need
- Choose how to fill the frame — If your video doesn't match the target ratio, pick a
fill method:
- Blur — Fills empty space with a blurred version of your video (most popular)
- White — Adds white bars (padding)
- Black — Adds black bars (letterbox style)
- Preview — Compare before and after to make sure it looks right.
- Download — Click "Resize Video", wait for processing, and download your file.
Tip: For Reels and Stories, "Fit with Blur" usually looks the most
professional. It keeps your full video visible while filling the vertical space naturally.
Instagram Video Size Guide (2026)
The correct dimensions for every Instagram format:
What happens if you upload the wrong size?Instagram will either crop
your video (cutting off the edges) or add its own black bars — and the result usually looks worse than if
you resize it yourself beforehand. Using the correct dimensions also avoids quality loss from Instagram's
re-compression.
Example: How to Turn a Landscape Video into an Instagram Reel
This is the most common scenario — you have a horizontal (16:9) video from your camera
or screen recording, and you want to post it as a vertical Reel.
Step 1: Upload your horizontal video.
Step 2 Click the "Instagram Reels (9:16)" preset.
Step 3: Your video is now wider than it is tall, so there's empty
space above and below. Choose "Fit with Blur" — this fills that space with a softly blurred
version of your footage.
Step 4: Click "Resize Video" and wait for
processing.
Step 5: Preview the result. Your original video is fully visible in
the center, with a clean blurred background filling the rest.
Step 6: Download and post to Instagram.
The same approach works for turning landscape into Stories, or square into portrait —
pick the preset, choose a fill method, and you're done.
Why Resize Before Uploading to Instagram?
Avoid Awkward Cropping
Instagram automatically crops videos that don't match the expected ratio. For Reels,
that means the sides of your landscape video get cut off. For Feed, it crops from the center. Resizing
beforehand gives you control over what stays visible.
Better Video Quality
Every time Instagram processes your video, it re-compresses it. Starting with the
correct dimensions (1080p) reduces the amount of processing Instagram needs to do, which means less quality
loss in the final result.
More Feed Space = More Engagement
A 3:4 portrait video takes up significantly more screen real estate in someone's feed
than a 1:1 square or 1.91:1 landscape. Monopolising the available space means you can command more
attention and higher engagement rates. It won't magically make a boring post exciting, but it will stop
you missing out on engagement for being in a suboptimal format.
Consistent Look Across Posts
If you're building a brand or a cohesive feed aesthetic, posting videos in
inconsistent sizes looks sloppy. Resizing everything to the same format keeps your profile looking
polished.
Custom Video Dimensions
Need a size that's not in our presets? Click "Custom" and enter any
width and height. The tool will resize your video to those exact dimensions.
This is useful for other platforms too — TikTok (1080×1920), YouTube Shorts
(1080×1920), Facebook Feed (1080×1080), LinkedIn (1920×1080), or any custom requirement.
Tip: Keep "aspect ratio" checked to avoid stretching. If you enter
just the width, the height will adjust automatically.
