A video shot on a phone or exported from an editor does not always land at the pixel dimensions you actually need. Uploading to a platform with strict size limits, fitting a clip into a template, or just shrinking an oversized file down to something more manageable all come down to the same problem: changing a video's width and height. The Video Resizer on File Tools Online does exactly that. Upload your video, set the dimensions you need, and download a video resized to match, without touching editing software. There is no dedicated resize option built into most editors' export screens beyond a handful of fixed presets, which is why a lot of people end up looking for a standalone tool once their footage does not match what they actually need.
Open the Video Resizer and choose the video you want to resize. Drag and drop it, or select it from your device.
Enter the width and height you need, or pick from the available size options.
Get your video at the new dimensions, ready to use, upload, or share.
Your original upload is not changed by the process, you receive a separate resized file.
Resize a video to the exact width and height you need.
Skip installing video editing software, upload and resize directly.
The tool runs in your browser, no desktop software or plugin required.
Resize a video from a laptop, desktop, or phone, using nothing more than a web browser.
Your file is processed over HTTPS and automatically deleted from our servers within 30 minutes.
There is no cost to resize a video or download the result.
Resizing a video changes its pixel dimensions, its width and height, rather than its length or content. A video shot at a large resolution can be resized down to a smaller frame, or a small clip can be scaled up, though scaling up will not add detail that was not already in the original footage.
The exact resize options this tool offers, whether that is typing an exact width and height, choosing from preset sizes, or setting a target aspect ratio, are set inside the tool's own interface and are not something we can confirm without testing the live tool directly. Whichever method it uses, the underlying operation is the same: changing the pixel grid your video is stored at. This is also distinct from cropping, which removes part of the frame rather than rescaling the whole image to a new size.
Needing to resize a video comes up in more situations than it might first seem, from meeting a platform's upload requirements to simply making an oversized file easier to work with. Most of these situations share a common thread: the video was produced for one context and now needs to fit into another, and the dimensions are the part that has to change to make that work.
These three tools sound related but each changes something different, and it is worth being clear about which one actually solves your problem before you upload. This Video Resizer changes a video's pixel dimensions, its width and height, which is what you want if a platform needs a specific size or your footage needs to be scaled to fit somewhere.
File Tools Online's Video Cropper is a different tool: it automatically trims a fixed percentage off the top and bottom of a video to remove black letterbox bars, it does not let you set a custom width and height or an aspect ratio. If your goal is dimension or aspect ratio changes rather than letterbox removal, this Video Resizer is the right tool, not the cropper.
If your real goal is a smaller file size rather than smaller dimensions, for example some of the "downsize" and "shrink" searches that lead people here, the Video Compressor may be a better fit, since it targets file size directly without necessarily changing the video's width and height. Resizing to smaller dimensions often does reduce file size as a side effect, but if dimensions themselves do not matter to you, compression is the more direct tool for the job.
The tool accepts common video formats such as MP4 and MOV as a source file to resize. If your source file is in a less common format, run it through the Video Converter first to get it into MP4, then resize the result. Confirm the full accepted format list against the live tool if you are working with an uncommon container or codec.
Scaling a video down to smaller dimensions generally preserves quality well, since you are reducing detail rather than adding it. Scaling up to larger dimensions is different, the tool can stretch or upscale the existing pixels to fill the new frame, but it cannot invent detail that was not captured in the original footage, so upscaled results are typically softer than true higher-resolution footage. The exact scaling method this tool uses internally is not something we can confirm without testing it directly, so if a clip needs to go noticeably larger, expect some softness rather than a sharper result.
Resizing a video traditionally meant opening dedicated editing software and adjusting export settings. The Video Resizer on File Tools Online skips that step entirely. There is nothing to download and nothing to install, whether you are on Windows, Mac, Android, or iPhone, you upload your video directly in your browser and download the resized result. For a quick, occasional resize, that is generally faster than opening and configuring a full video editor.
Because the Video Resizer runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is nothing tied to one operating system, so you can resize a video on whichever device you happen to have it on.
It changes a video's pixel dimensions, its width and height, to whatever size you set.
No, resizing only changes the video's dimensions. Its length and content stay the same.
The Video Cropper automatically removes a fixed percentage from the top and bottom to strip black letterbox bars. This tool lets you change the actual width and height instead.
Not necessarily. If file size is your main concern rather than the dimensions themselves, the Video Compressor targets that more directly.
The tool accepts common video formats such as MP4 and MOV. If your file is in a less common format, convert it to MP4 first with the Video Converter, then resize the result.
Scaling down generally preserves quality well. Scaling up can look softer, since the tool cannot add detail that was not in the original footage.
You can upload and resize videos one at a time, repeating the process for each additional video.
Yes. Upload your video to the Video Resizer and download the result, there is no cost to use it.
No. Upload your video and resize it directly in your browser, no software installation required.
Yes. The tool runs in your browser, so it works the same way on Windows, Mac, Android, and iPhone without installing anything.
No. Your original upload is not altered, you receive a separate resized file.

File Tools Online is a collection of free, browser based tools for working with audio, video, PDF, and image files, built for people who need a quick, reliable result without installing software. The Video Resizer is one part of a larger set of video tools, so once your video is at the right dimensions, you can crop, compress, or convert it using the other tools in the same toolkit.
Resizing video used to mean opening a full editor just to change a width and height, and browser based tools have made that kind of small, specific adjustment available without the overhead of a complete editing suite. Set the dimensions you need, download the result, and move on, no timeline, no export settings menu, and no learning curve for a task that should only take a minute.
