I built a free in-browser video compressor — the file never leaves your device
I wanted a compressor I could trust with client footage. Most "online video compressor" sites upload the file to a server. That's slow, and it's a privacy problem. So I built VideoCompress : compression runs in the browser. The video is not uploaded. What it does Drop in MP4, MOV, WebM, MKV, AVI, and similar Set a target size in MB (Discord 10, email 25) or pick High / Balanced / Small Optional…
The author sought a dependable video compressor for client footage, avoiding online sites that upload files to servers and pose privacy concerns. Thus, they developed VideoCompress, a tool that compresses videos directly in the browser without uploading the file. The software accepts various video formats, including MP4, MOV, WebM, MKV, and AVI.
Users can set a target size in megabytes (MB), ranging from Discord's 10MB, email's 25MB, to options like High, Balanced, or Small. An optional feature allows downscaling to 1080p, 720p, or 480p. The final output is a compatible MP4 file (H.264 + AAC). The service is accessible via videocompress.dev, with no account required, no watermarks, and no file-size paywalls.
The compression process relies on WebCodecs when the browser supports it, or falls back to FFmpeg compiled to WebAssembly. This ensures processing remains on the user's device, with the practical limit being the machine's capabilities rather than server quotas. The author suggests this tool is ideal for quickly compressing a video clip (e.g., for Discord) without installing additional software or sending the file to an unknown encoder.
