The toolkit

Three tools, one job: smaller files

Every format you ship to production — images, fonts, video — compressed the right way, without a build pipeline or a CDN bill.

→ AVIF

Image Compressor

Resize, crop, rotate, flip and compress — then save as AVIF, WebP, JPEG, PNG or JPEG XL, or keep the format you uploaded. Each edit applies to the result of the last.

  • Crop with aspect-ratio presets
  • Batch process many images at once
  • Convert to AVIF, WebP, JPEG, PNG or JXL
Compress an image
→ WOFF2

Font Compressor

Subset and convert TTF, OTF, or WOFF fonts to Brotli-compressed WOFF2. Pick exactly the characters your site uses — nothing more.

  • Visual character picker
  • Paste your copy to auto-select glyphs
  • Batch-compress a whole font family
Compress a font
→ MP4

Video Compressor

Hardware-accelerated H.264 encoding using your device's own video chip. Target a file size and let the tool find the right bitrate.

  • Target output size (e.g. under 1.5MB)
  • Resolution and audio controls
  • Batch-compress multiple videos
Compress a video
→ Transparent PNG

Background Remover

Cuts the subject out of a photo and hands back the same file with a transparent background — identical width, height and colour. No resolution cap and no watermark.

  • Keeps the original resolution exactly
  • Openly licensed models, runs on your CPU
  • Transparent or solid-colour background

How it works

No accounts. No uploads. No waiting.

Every tool runs the same way — your file never touches a server.

1. 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.

2. Adjust settings

Tune quality, target size, character set, or resolution. A live preview shows exactly what you'll get before you commit.

3. 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. Devdwell Tools never does that.

  • Zero uploadsEvery compression runs with WebAssembly and WebCodecs, directly in your browser tab.
  • Nothing storedClose the tab and the file is gone. We never see it, let alone keep it.
  • Works offlineOnce a tool's loaded, you can disconnect from the internet and keep compressing.
Questions

Common questions

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.

Your files. Smaller. Right now.
