Frequently Asked Questions

Why change a video's resolution?+

Lower resolutions dramatically cut file size for messaging and email, while the vertical and square presets fit TikTok, Reels, Shorts and Instagram formats exactly.

Does reducing resolution reduce quality?+

It reduces pixel count, which on small screens is barely noticeable. A 720p video on a phone looks nearly identical to 1080p at half the size.

Can I increase resolution to make a video sharper?+

Upscaling is possible but adds no real detail — the player just stretches pixels. It only helps when a platform demands a minimum resolution.

What happens with the aspect ratio presets?+

The video is scaled to the chosen dimensions. Choosing a preset with a different aspect ratio than the source will stretch the image, so pick one matching your footage.
