Which tool do you need?
File too big to send? Start with the Video Compressor. If it barely shrinks, the clip is already efficiently encoded; trimming it shorter is the next most effective step.
Posting to TikTok, Reels or Shorts? Use the Video Cropper to trim the clip and turn landscape footage into 9:16, then compress it if the app still rejects the size.
Only need the sound? Video to MP3 saves the audio track, which is far smaller than the video. For a silent looping reaction or demo, use Video to GIF.
How your videos are handled
Every tool uses FFmpeg, the open-source media engine, compiled to WebAssembly so it can run inside the browser tab. Your file is read with the browser's File API, processed in memory and offered back as a download. It is not sent to FastSaveMedia. Encoding on one processor core is slower than a desktop app, so long or high-resolution videos take time, particularly on phones.
Frequently asked questions
Are my videos uploaded to a server?
No. Each tool downloads the open-source FFmpeg engine into your browser and processes the video on your device. Only the engine files come from a public content network; your video is not sent with those requests.
How large can my video be?
The tools accept files up to 250 MB. Everything happens in your browser's memory, so phones handle shorter clips better than very long recordings.
Why is the first run slower?
The first time you process a video, the browser downloads the roughly 25 MB processing engine. It is cached afterwards, so later runs start quickly.
Which browsers work?
Current versions of Chrome, Edge, Firefox and Safari, including on Android, iPhone and iPad. The engine runs on one processor core so it does not need special browser settings.
Do the tools add a watermark?
No. The output contains only your video, audio or GIF. There is no account and no watermark.
