No accounts. No uploads. No waiting.
Every tool runs the same way — your file never touches a server.
Drop your file
Drag a file in, or click to browse. It loads straight into your browser's memory — no network request, no progress bar waiting on bandwidth.
Adjust settings
Tune quality, target size, character set, or resolution. A live preview shows exactly what you'll get before you commit.
Download
Your compressed file saves straight to your device. No account, no email, no watermark — just a smaller file, ready to ship.
Why it matters
Your files stay exactly where they are: on your device
Most "free" compression tools upload your file to a server, process it remotely, then send it back. That's slower, and it means a stranger's infrastructure briefly holds your unreleased product photos, your client's video, or your company's brand fonts. Imbuz never does that.

Questions
Common questions
Every tool page has its own questions too — the Image Compressor and Background Remover go deepest.
Is this actually free?
Yes — every tool is free with no usage limits, no watermarks, and no account required. There's no paid tier; the tools run on your hardware, not ours, so there's no server cost to recoup.
Do you store or see my files?
No. Files are never uploaded to any server — compression happens with WebAssembly and the browser's native WebCodecs API, directly on your device. We have no way to access, store, or view what you compress.
Why does my video need hardware encoding support?
The Video Compressor uses your device's built-in video encoder via the WebCodecs API for speed — this is the same hardware your browser already uses to play video smoothly. It's supported in current Chrome, Edge, and Safari; Firefox support is still rolling out.
What's the maximum file size?
There's no artificial limit set by us — the practical ceiling is your device's available memory. Most modern laptops and desktops handle files well into the gigabytes without issue.
Can I compress multiple files at once?
Yes — both the Font Compressor and Video Compressor support batch uploads. Drop several files at once, and each is queued and compressed in turn, with a single download for the whole batch as a ZIP.
Why AVIF, WOFF2, and MP4 specifically?
They're the formats with the best compression-to-compatibility ratio for the modern web. AVIF beats JPEG and WebP at equivalent quality, WOFF2's Brotli compression is the smallest valid web font format, and H.264 MP4 remains the most universally supported video codec across browsers and devices.
