Frequently asked questions
Is Video Resizer really free?
Yes — completely free, with no hidden fees, no premium tier and no signup required. The tool runs entirely in your browser.
Do I need to install anything to use Video Resizer?
No. Video Resizer works directly in your browser. There is no software to install, no app to download and no plugin required.
Is my video uploaded to a server when I use Video Resizer?
Never. All processing happens locally on your device. Your file never leaves your computer, which is why there is no upload wait and no privacy risk.

What happens to my file after processing?
Nothing is stored anywhere. Once you close the tab, everything is gone. We have no server, no storage and no access to your files.
Will my video have a watermark?
No — every download is 100% watermark-free. EditVideo never adds logos, branding or watermarks to your files.
Can I resize a video for YouTube or Instagram?
Yes — 1080p and 720p fit YouTube and Instagram perfectly, 480p and 360p are for quick sharing. Aspect ratio stays intact, output stays crisp.
How do I resize a video for YouTube?
Pick 1920×1080 (or 1280×720) in our resize tool — YouTube's standard. Keep the same aspect ratio to avoid black bars; our tool preserves it automatically. Everything else (codec, frame rate, audio) stays at YouTube-friendly defaults.
Does resizing a video reduce its quality?
Downsizing (e.g. 4K to 1080p) keeps all visible detail — you're just discarding pixels the screen can't show. Upsizing (e.g. 720p to 1080p) stretches fewer pixels over more space, so fine detail softens; that's where our AI upscaler helps. For best results, always resize downward, never upward.
