Good to know
The resolution changer scales the entire visible video proportionally to a new pixel resolution directly in your browser, without cropping anything. The target method can be a preset resolution, a target edge (width or height, with the other side calculated proportionally), or a percentage scale.
Typical searches include change video resolution, resize video to 1080p, and reduce MP4 resolution. An upscale option is disabled by default to avoid unwanted quality loss when the target resolution exceeds the source video. Upscaling does not add real detail; downscaling can reduce perceived sharpness.
Typical use cases
Downsize a video for faster upload
Choose a lower preset resolution or a percentage scale to significantly reduce file size before uploading.
Adapt a video to a fixed target width
Enter a target edge such as 1280 pixels width, so the height is calculated automatically and proportionally.
Tips for better results
Only enable upscaling deliberately
Since upscaling is disabled by default and does not add real detail, only enable the option when a higher target resolution is technically required.
Choose the target method to match the purpose
Use a preset resolution for common formats, a target edge for exact platform requirements, or percent for relative downsizing.

Features
Three target methods
Preset resolution, target edge with proportional calculation, or percentage scaling.
Proportional scaling without cropping
The entire visible picture is scaled without cropping any content.
Upscaling disabled by default
Prevents unintended quality loss when the target resolution exceeds the source video.
Frequently asked questions
Frequently asked questions
Does upscaling add real image quality?
No. Upscaling enlarges the image computationally but does not add real detail — the option is therefore disabled by default.
Is my video uploaded?
No. Scaling runs entirely locally in the browser, without transmission to a server.
