Resize Video — FAQ
Is this video resizer really free?
Yes — resize as many videos as you like, free, with no signup and no watermark. An optional Pro membership (NZ$9/mo) unlocks full 1080p output and batch resizing, but the free tool handles everyday resizing on its own.
Is my video uploaded anywhere?
No. Your video is read and re-scaled entirely in your browser using a local video engine. The file never leaves your device — there is no server and nothing is stored online.
Will resizing keep the aspect ratio?
Yes. The presets scale by height and the custom option scales by width, with the other dimension worked out automatically so your clip never looks squashed or stretched. Dimensions are snapped to even numbers, which H.264 requires.
Which formats can I resize?
Anything your browser can play — typically MP4, WebM and MOV. The result is always an MP4 (H.264), which plays just about everywhere and uploads easily.
Should I resize a property video before uploading?
It is a great idea — dropping an Auckland listing walkthrough or open-home clip from 4K down to 1080p or 720p makes it far quicker to upload to a portal or share on social, with barely any visible difference on a phone screen.
Why is a big or long video slow on my device?
Everything happens on your device with a single-thread engine, so large or long clips can take a while — especially on a phone. For the quickest result, resize a shorter clip or pick a smaller resolution.
