One clip, ready for every feed
Presets for every platform
Pick ready-made sizes for TikTok, Instagram Reels, YouTube Shorts, Stories, and square feed posts without doing the math.
Blurred background fills the frame
When the aspect ratios don't match, a blurred version of your video fills the gaps so nothing is stretched or cropped away.
Your video stays on your device
The clip is resized in your browser and never uploaded to DojoClip, so drafts and private footage stay yours.
Free, no sign-up, no watermark
Download the resized video with no account, no queue, and no DojoClip watermark added.
Works with the files you already have
Import MP4, MOV, WebM, MKV, AVI, and more. MP4, MOV, and WebM are the most reliable across browsers.
Fast for everyday clips
Short and medium clips resize in seconds to a couple of minutes, depending on your device.

One video, every aspect ratio
TikTok, Reels, and Shorts want vertical 9:16. Instagram feed likes square. YouTube stays 16:9. Reformatting the same clip for each one usually means fiddly cropping or re-exporting. This resizer does it with a preset: pick the platform, and your clip is reframed to fit, right in your browser.
No stretching, no awkward crops
When a horizontal clip goes vertical, something has to fill the space. Instead of stretching the image or cutting off the edges, this tool places your video on a blurred version of itself, so the full frame stays visible and the result still looks intentional on a phone.
Add captions and branding, or shrink for upload
Once the size is right, take it further in the AI Video Editor to add captions, music, and branding for social. If the resized file is too big for an upload, reduce it with the free video compressor.
FAQ
Which platforms and sizes are supported?
Vertical 9:16 for TikTok, Reels, Shorts, and Stories, square 1:1 for feed posts, and landscape 16:9 for YouTube, plus other common social presets.
Is the social media resizer free?
Yes. It is free with no sign-up and no watermark. It runs in your browser, so there is no server bill for us to pass on to you.
Is my video uploaded to a server?
No. Your browser resizes the clip locally, so the video never leaves your device - useful for client drafts and private footage.
What happens when the aspect ratios don't match?
Instead of stretching or cropping, a blurred copy of your video fills the empty space, keeping the whole frame visible and on-brand.
Which browsers work best?
Chrome and Edge give the most reliable results. MP4, MOV, and WebM sources are the safest inputs.
