Smaller frame + compression setting → H.264 video / AAC audio in an MP4 containerHow to use this video compressor
- Choose an MP4, MOV or WebM up to 50 MiB and two minutes long.
- Choose a 720- or 1080-pixel maximum long edge and a quality setting. Optionally remove audio.
- Start processing, review the returned file size and preview, then download your MP4.
Worked example
A 1920 × 1080 landscape source exported with a 720-pixel maximum long edge becomes approximately 720 × 404 after even-pixel rounding. A smaller source is not enlarged. The final byte size depends on the picture, sound and quality setting; the result card reports the actual bytes instead of promising a fixed reduction.
Compress a video with a real downloadable export
This tool uploads your selected file directly to the media API and creates a new H.264/AAC MP4. It does not just estimate a size or alter a browser preview. Processing happens on the server, so the page does not need a large WebAssembly encoder download. Source and result previews use the browser’s native video player.
Choose quality and frame dimensions together
The maximum long edge limits the larger dimension while retaining the shape, rounded for compatible video encoding. Higher quality generally uses more bytes; the smaller-file setting trades more fine detail for size. Exports use 30 fps and a bounded bitrate. Re-encoding can change colour and fine text, so inspect the result before delivery.
Check actual bytes rather than assuming a saving
An already efficient source can become larger after conversion. When that happens, the result says so and suggests a smaller frame or lower quality. This tool does not target an exact megabyte limit. Use the video file-size calculator when you want to model a bitrate and duration budget before an export.

Common questions
Can I compress MOV or WebM into MP4?
Supported MOV and WebM inputs are decoded and exported as H.264 video with AAC audio in MP4. Input acceptance depends on the actual codec and metadata, not only the filename. Standard H.264, HEVC, VP8, VP9, AV1 and MPEG-4 video codecs are supported within the displayed limits.
Does compression preserve original video quality?
No lossy re-encode can promise identical picture quality. Smaller frames and stronger compression can remove detail. Preview text, gradients, faces and motion before using the export. The original local file remains unchanged.
What are the free video limits?
Files can be up to 50 MiB, two minutes, a 3840-pixel maximum side and roughly 8.3 megapixels, at up to 60 fps. Sources must use square pixels and standard dynamic range. Exports are limited to 100 MiB. Free starts are rate-limited and subject to media-server capacity.
Are videos uploaded or kept in my library?
Videos are uploaded to the media API for processing. This tool does not add them to your AdManage library. Temporary server files are removed after the response or failure, and older abandoned files are swept automatically. Download the result before leaving the page.
