Frequently Asked Questions
Find answers to the most common questions about this tool.
No — this video compressor runs entirely in your browser using WebAssembly, the same technology that lets complex software run at near-native speed inside a web page. Your video file is processed on your own device from start to finish and is never transmitted to ToolFlexy's servers, which makes it safe for private or personal footage.
A video compressor reduces a video's file size so it's easier to send over email, WhatsApp, or messaging apps with attachment limits, or to save storage space, without needing to re-export the file from a full video editor. It's also useful for uploading faster to social platforms or cloud storage with size caps, and for keeping backups of large video libraries from eating up your device's storage.
Maximum Compression produces the smallest possible file, ideal for messaging apps with strict size limits. Balanced finds a middle ground between size and visual quality. Best Quality keeps the video as close to the original as possible while still reducing size. Custom Target Size lets you pick your exact desired output size in MB, and the tool calculates the right settings automatically.
It depends on the mode you choose. Best Quality is built to minimize any visible difference from the original, while Maximum Compression prioritizes the smallest file size and will show more visible quality reduction. The live size estimate for each mode lets you preview the tradeoff before committing to a setting, so there are no surprises after downloading.
The tool supports videos up to 250MB, with no daily usage limits, no account required, and no cost to compress your files. There's also no watermark added to your downloaded video, regardless of which compression mode you use, and you can compress as many videos as you need.
You can upload MP4, MOV, WEBM, and most other common video formats, and the compressed output is always delivered as a standard MP4 file, ready to share, upload, or play back on virtually any device or platform without conversion issues. MP4 was chosen as the output format specifically because it has the widest support across phones, browsers, and social platforms.
Yes — a one-click checkbox lets you strip the audio track entirely before compressing, which is useful for silent clips or background video where audio isn't needed and only adds to the file size. This can noticeably shrink the final output on its own.
Use Custom Size and target around 10-25 MB for most email attachment limits, or Balanced mode for social platforms like Instagram and WhatsApp, which re-compress video anyway — starting smaller just makes the upload faster.
