Video Resize
Change the dimensions of a video while maintaining the aspect ratio
Resize Video Online - Change Video Resolution Free
EzyIMG's Video Resize tool changes your video's width and height to any standard resolution (1080p, 720p, 480p) or a completely custom pixel size. Content creators use it to transcode large 4K footage into a 1080p web-ready version, or to make a landscape recording fit a square format without cropping. Whether you need to reduce file size or match a target platform's resolution requirements, this tool handles the conversion in seconds.
All video resizing is performed locally in your browser using FFmpeg compiled to WebAssembly. No video data is ever uploaded to any external server. The entire process runs inside your browser tab. No account is required to use the tool and the output video contains no EzyIMG watermark. This browser-based approach also means your original footage stays private regardless of what it contains.
