Resize a video / change resolution, free

Resize a video without an upload

Drop your video, pick a resolution preset, and download, all in your browser.

Stays on your device

Your video is scaled locally and downloaded straight back to you.

When you’d want this

Platform upload limits are the most common reason. Twitter/X caps uploads at 1080p; Instagram Reels are 1080p natively. Going from 4K to 1080p cuts file size by 70–80% while still looking sharp on any normal screen.

A common one: you have a 4K screen recording that’s too heavy to drop into a chat thread. Scaling it to 720p makes it upload in seconds and still reads clearly at the size most people watch it.

The other common case is making a smaller proxy to edit in a lighter app. Work on the small version, then re-export from the original when you’re done.

What stays the same

The aspect ratio is preserved: a 16:9 clip stays 16:9 at any preset, with no letterboxing or cropping. The audio track, frame rate, and color profile are all carried through unchanged. Re-encoding is required for a resize, so the output is H.264 MP4 (the universal fallback codec).

Resolution presets

Preset	Pixels	Typical use
1080p	1920×1080	Social, streaming, most screens
720p	1280×720	Faster uploads, older devices
480p	854×480	Small embeds, low-bandwidth
360p	640×360	Preview clips, tiny files

Common pitfalls

Resizing up is usually a mistake. A 360p source scaled to 1080p has no extra detail to fill in, so it looks blurry or blocky while taking a much larger file. Only downscale from a higher-resolution original.

If the source has a non-standard aspect ratio (vertical phone video is typically 9:16, for example), the output matches that ratio at the chosen preset height. A “1080p” vertical video will be 1080 pixels tall, not wide, because the tool scales to fit the shorter dimension. For precise control over output dimensions, use a full video editor.

Privacy

The resize runs in your browser via WebAssembly. Whether the clip is an internal demo, a client call, or anything you’d rather not hand to a third party, it stays a local file from drop to download. There is no upload, no server, and no account.

Smaller file too?

Lower resolution shrinks the file; for a specific target size, re-encode at a lower bitrate.

Need the words too?

Need the recording as text as well? Turn it into a speaker-labeled transcript you can search and quote.
