Change your video’s aspect ratio without cropping it
Your video, in the format it needs to be. Upload a clip, choose a new aspect ratio, and get a version where the frame expands to fit. The composition stays intact and nothing gets cut off.
A smarter way to change video format
Many resizing tools crop or stretch to fill the new frame. The Video Aspect Ratio Changer works differently. Upload your video, pick a target ratio, and the scene is intelligently expanded beyond its original edges, filling in new detail so the result looks natural, not forced.
One upload, one choice, one output
No timeline editing, no manual reframing, and no export settings to configure. Upload your video, pick the ratio you need, and you’re done. The kind of edit that used to take a proper setup now takes seconds.
Built for every video project
One video shouldn’t mean one format. Whether you’re posting to social, delivering to a client, or repurposing footage for a new placement, get the ratio you need without going back into an editor.
From one video to any social platform
Shoot once and post everywhere. Turn landscape footage into vertical clips for Reels, Shorts, or TikTok without cropping out the parts that matter.
Adapt campaigns for every channel
Got a hero ad in 16:9? Get it into the formats your other placements need. Repurpose campaign footage across social, display, and web without a full re-edit. Great for product launches and always-on campaigns.
Deliver in the format your client needs
When a client needs the same video in a different format, don’t rebuild the edit. Upload, pick the ratio, and deliver a clean output that looks like it was always framed that way.
Frequently asked questions
Artlist's Aspect Ratio Changer is an AI app that converts your video into a new format without cropping or stretching the original footage. Upload a video, choose a target aspect ratio, and the tool intelligently expands the scene beyond its original edges, filling in new detail so the composition looks natural in the new frame.
The app supports six output formats: 16:9, 9:16, 4:3, 3:4, 21:9, and 9:21. These aspect ratios cover the most common ratios for social, web, professional delivery, and ultrawide formats.
No. Unlike standard resizing tools, the Aspect Ratio Changer expands the frame rather than cutting into it. The original composition is preserved, and any new area introduced by the format change is filled in intelligently, so nothing important gets lost.
