Free file tools that
respect your privacy
Merge, convert, compress and split your PDF, Excel, CSV and image files — all processed right inside your browser. Nothing is ever uploaded to a server.
How it works
Three simple steps. No account, no upload, no waiting on a server.
Pick a tool
Choose from PDF, image, Excel and CSV tools — merge, convert, compress, split and more.
Add your files
Drag & drop or browse. Your files load straight into your browser — never onto a server.
Download instantly
The work runs on your device and your finished file downloads right away. Done.
Why SimpleFileKit?
Built for anyone who handles sensitive documents and doesn’t want to hand them to a stranger’s server.
Private by design
Most converters upload your document to process it. Ours don’t — every tool works locally, so contracts, payroll and personal scans stay yours.
Fast, no queue
There’s no server round-trip. Files are processed instantly on your own device, even offline once the page has loaded.
Free & unlimited
No sign-up, no watermark, no file-size cap beyond your device’s memory. Every tool is free to use as often as you like.
Works everywhere
Runs in any modern browser on desktop, tablet and phone. Nothing to install and nothing to update.
Frequently asked questions
Are my files uploaded to a server?
No. Every tool runs entirely inside your browser using JavaScript. Your documents, spreadsheets and images never leave your device — there is no upload step and no server that ever receives your files.
Is SimpleFileKit really free?
Yes, completely free. There is no sign-up, no account, no watermark, and no trial. The site is supported by unobtrusive ads.
Do I need to install anything?
No. Everything works in a normal web browser on desktop or mobile. There is nothing to download or install.
Is there a file-size limit?
There is no fixed limit. Because processing happens on your own device, the only limit is your device’s available memory. Very large files use more of your computer’s resources.
Which browsers are supported?
All modern browsers — Chrome, Edge, Firefox and Safari — on desktop and mobile. The AI background remover works best on a modern desktop browser.
