Upload a video file and scale it to a new resolution. The aspect ratio is preserved, and the video is re-encoded, so longer files take a while.
Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.
Set a width, height, or both, and the tool re-encodes your video at the new dimensions. Specify one side and the other follows the aspect ratio automatically; specify both and choose how the frame should fit.
Downscaling 4K to 1080p or 720p slashes file size with modest visual cost on most screens. Platforms and embeds often want specific dimensions. And email or chat limits frequently fall to a resolution drop alone, before any bitrate compromise.
