React Server
Lokafile is a set of browser-based file tools: PDF merge, split and compress, image conversion, and more. The difference from most online file converters is architectural. Lokafile does all processing client-side using JavaScript in your browser. Your files are never uploaded, never queued on a server, and never stored. You can verify this yourself — open your browser's network tab while using any tool and you'll see no file data leaving your machine. This means it works on documents you wouldn't want to hand to a third party: contracts, medical records, financial statements, anything confidential. Free to use, no account, no file size limits imposed by upload bandwidth.
LokafileLokafile's answer
Lokafile does all its file processing in your browser. There's no upload step, no server-side queue, and no copy of your file sitting on someone else's disk waiting to be deleted. Most online file tools work the other way round: you upload, a server processes, you download, and you trust a privacy policy about what happens next. Lokafile removes the trust requirement rather than asking you to extend it. You can verify this yourself — open your browser's network tab while using any tool and watch for file data leaving your machine. There isn't any.
Lokafile's answer
If your file isn't sensitive, honestly, the big incumbents work fine and have more features. Use them. Lokafile is for the other case: the contract, the medical letter, the bank statement, the document with a client's name on it. For those, "we delete files after two hours" is a promise; "the file never left your laptop" is an architecture. That's the whole difference. Practical upshots: it works offline once loaded, there's no queue at busy times, no account, and no file size cap imposed by upload bandwidth — your browser's memory is the only limit.
Lokafile's answer
People handling documents they'd rather not hand to a third party — freelancers and small businesses dealing with client paperwork, anyone working with medical, legal, or financial documents, and people in regulated jobs where uploading a file to an unknown server is a policy problem rather than a preference. Also, plainly: anyone who wants to merge two PDFs without making an account.
Lokafile's answer
It started from noticing that every free file tool online wants your file on their server, and that for most of what those tools do, there's no technical reason it has to work that way. Browsers have been able to do this work locally for years — the upload model persists mostly because it's how these businesses are built. I had no coding experience when I started. The site is ten tools, each doing one thing properly, plus guides explaining the underlying tasks. It's deliberately small — the goal was tools that genuinely work rather than a large catalogue of half-finished ones.
Lokafile's answer
Vanilla JavaScript, running entirely client-side. jsPDF for PDF generation, the Canvas API for image work, and the File API for local file handling. Static HTML/CSS, no framework. Progressive web app with a service worker, so it works offline once loaded. Hosted as static files on Netlify — there's no backend to send anything to, which is rather the point.
