Change video resolution: uses and practical guidance
Choose a video and the target resolution: 1080p, 720p, 480p, 360p or 240p. The number refers to the shorter side, so a vertical 1080 × 1920 video becomes 720 × 1280 when you choose 720p. The resulting dimensions are rounded to even numbers, which codecs require, and the aspect ratio is preserved. You can only reduce: if the video is already equal to or smaller than the chosen resolution, you are told instead of enlarging it, because enlarging adds no detail. The video is re-encoded at high quality and the audio is kept. Reducing the resolution also reduces the file size. Input limit: 500 MB.
Change video resolution. The video is opened and processed in your device’s memory and is never sent to a server, so speed depends on your computer and the file size. Copying tracks without re-encoding is almost instant; re-encoding can take several minutes for long or high-resolution videos. While it works, the page shows progress and a cancel button. Keep the tab open and visible until it finishes, because some browsers slow down background tabs. The 500 MB limit protects device memory. If the file is larger, split it into parts first. The original is never modified: the tool creates a new file that you download.
Change video resolution. Play the complete result before using it: check that picture and sound stay in sync, that no seconds are missing at the start or end, and that quality is sufficient for your purpose. Open the file in another player or in the application where you will publish it, because every platform has its own limits for duration, size and format. If the result does not play, try MP4, the most compatible format. Always keep the original video until you have verified the new one, and do not overwrite the source file. If the video contains personal data, remember that this tool does not hide faces or voices: it only changes the file.

Frequently asked questions
Is it free, and do I need to sign up?
Yes, it is free. You do not need to sign up, create an account or install an app, and there is no daily quota: open the tool and use it. The only limits are file sizes, which protect your device’s memory.
Does it leave a watermark on the result?
No. Snipshed adds no watermark, logo or text of its own to the files you download: the result is yours exactly as you configured it.
Is quality lost?
This operation re-encodes the video, so a small quality loss is possible. Keep the original and check the whole copy before using it.
Does it work on iPhone and Android?
Yes, from your phone’s browser (Safari, Chrome…) and without installing any app. When it finishes, the file is saved from the browser itself: on iPhone it appears in the Files app and on Android in Downloads. With very large files the phone may run out of memory; try a smaller file or a computer. Video operations need a recent browser with WebCodecs, such as current versions of Safari and Chrome.
Guides
Understand compression, resolution, frame rate and containers so you can prepare a smaller copy that plays correctly.
Check what makes a video heavy, compress it, lower its resolution and convert an iPhone MOV to MP4 before you send it.
