4 toolsWhy FileMancer?
Instant
No upload queue and no round trip to a server. The conversion starts the moment you paste, and finishes before you have moved the mouse.
Private by design
Everything runs inside your browser tab. Your files and text are never sent anywhere, so there is nothing to leak, log or delete afterwards.
Free, with no catch
No usage limits, no watermarks, no locked features and no "upgrade to download" screen at the end.
No account needed
Nothing to sign up for. Favourites and recent tools are remembered on your device, not on ours.
Frequently asked questions
Everything you might reasonably want to know before pasting something in.
Is FileMancer free?
Yes, completely. Every converter listed here is free to use with no limits on how many times you use it, no watermarks and no sign-up wall.
Are my files uploaded?
No. Every converter on the site runs entirely in your browser using JavaScript and standard web APIs. Your files and text never leave your device, which is why conversions are instant even for large files.
Do I need an account?
No. There is nothing to sign up for. Favourites and recently used converters are remembered on your device using local storage.
What file types are supported?
Data formats (JSON, CSV, YAML, XML, SQL), text encodings (Base64, URL, HTML entities, Markdown), images (JPG, PNG, WebP, GIF, BMP, SVG) and PDF output. Browse all converters to see the full list.
How large a file can I convert?
Image and document converters accept files up to 50 MB. Text converters have no fixed limit — the practical ceiling is how much your browser can hold in memory, which is usually several megabytes of text without any trouble.
Does it work offline?
Once a converter page has loaded, the conversion itself needs no network connection. The site is installable as an app, so you can keep it on your home screen or dock.
