Compress Video for Google Drive
Upload Faster & Use Less Cloud Storage
Shrink Videos Before Cloud Upload — Privately in Your Browser
Compress video for Google Drive before you hit upload. SmallFast shrinks MP4, WebM, and MOV files locally so Drive sync finishes sooner and your cloud quota lasts longer. The same flow works for Dropbox, OneDrive, and other cloud storage — without sending the original to a random online compressor.
Why In-Browser Compression is 100% Private
Most online compressors secretly upload your media to their cloud servers, storing photos and videos where they can be scanned, logged, or compromised. SmallFast changes the paradigm entirely.
0 Bytes Uploaded
Files stay strictly in your device memory. When you compress media with SmallFast, zero bytes of image or video data are transmitted over the internet.
Client-Side WebAssembly
We leverage modern WebAssembly (Wasm) and local hardware acceleration. Your CPU and GPU handle the compression math at full native speed.
Independently Verifiable
You do not have to take our word for it: open your browser Developer Tools (F12), inspect the Network tab, and observe that not a single upload request is made.
How to Compress Media Online
Optimize high-resolution images and heavy videos in seconds right inside your browser window.
Select or Drop Files
Drag and drop your media into the online compressor or pick files from your computer or phone. Files load instantly into your browser memory without being uploaded anywhere.
Customize Quality & Size
Adjust quality sliders, pick target resolution, or convert format with instant visual comparison. Fine-tune until you achieve the exact balance of size and sharpness.
Download Compressed Media
Export your compressed images or videos directly to your device with one click, or package multiple items into a single ZIP file. Your originals remain untouched.
