Why Client-Side?
Most online tools work by uploading your files to a server.
Client-Side Kit
takes a different approach.
What "Client-Side" Means
Client-side means the tool runs entirely in your browser, on your device.
When you use a Client-Side Kit tool:
- Your files stay on your computer
- Processing happens locally using JavaScript and WebAssembly
- Nothing is uploaded to a server
- No copies are stored anywhere
Some tools use your browser's local storage to save your work â so you don't lose progress if you refresh. But that data stays on your device, managed by your browser, and is never sent to us.
Why This Matters
Uploading files might seem convenient â but it comes with tradeoffs.
Privacy First
Your files never touch our servers. No uploads means no exposure â ideal for personal docs, sensitive work, or anything you'd rather keep private.
Instant Speed
No waiting for uploads, processing queues, or downloads. Everything happens immediately on your device.
Works Offline
Once loaded, many tools keep working without internet. Perfect for travel, spotty connections, or secure environments.
Full Transparency
No mystery about what happens to your data. No background processing. No hidden storage. What you see is what runs.
Why Aren't All Tools Client-Side?
Some tasks genuinely require servers â but many don't. Historically, browsers were limited. Today, they're powerful enough to handle:
Client-Side Kit exists to prove that many everyday tools don't need uploads at all.
The Client-Side Kit Philosophy
"If a tool can run safely and efficiently in your browser, it should."
That means:
Just fast, focused tools that do one thing well.
When Client-Side Tools Are a Good Fit
Client-side tools are ideal when you:
They're not meant to replace everything â just the tools that shouldn't need a server in the first place.
Built for Trust
Client-Side Kit is intentionally boring in the best way.
Just tools you can use, bookmark, and trust.
The web doesn't need more upload forms.
Sometimes, it just needs better tools.
