File Content Conversion is a free, browser-based file conversion tool. We built it around a simple idea: converting a file shouldn't require handing it over to a stranger's server. Every converter on this site - from DOCX to HTML, CSV to JSON, PNG to WebP, and more - runs entirely inside your own browser using client-side JavaScript.
That means your files never leave your device. Nothing is uploaded, nothing is stored on our servers, and nothing is scanned or processed remotely. The conversion happens locally, on your machine, using the same browser tab you're reading this page in. When you close the tab, the file and its converted output are gone unless you've downloaded them yourself.
We designed the site to be fast and frictionless: no account, no signup, no email address, and no payment information required. Pick a conversion, drop in a file, and get your result in seconds. That's the whole experience.
Pick the conversion you need from the homepage - DOCX to HTML, CSV to JSON, PNG to WebP, and more.
Drag a file into the drop zone or select it from your device. It stays on your machine the whole time.
JavaScript running in your browser tab does the work instantly - nothing is sent anywhere.
Save the converted file straight to your device. Close the tab and everything is gone unless you kept it.
Files are processed locally. We have no server-side pipeline that ever sees your file contents.
No tiers, no watermarks, no "free trial." Every converter on this site is free to use for as long as it exists.
No account, no email capture, no password. Open a converter and use it immediately.
We support the file formats people actually work with day to day - documents, data, images, and text.
19 free converters. No upload. No account.
Your files never leave your browser.
