Yes, with no watermark and no page limit.

Does it need an account?

No. There is no account system.

Is my file processed on my device?

Yes. The file is read by your browser and never uploaded. There is no server to send it to.

What formats are supported?

Anything at all goes in, because the matching is on the name and the type. What comes back is the list of tools that can genuinely open it, and nothing when none can.

This one routes rather than converts: it names the tool and hands you over. A format nothing here reads gets an honest empty answer instead of a page that pretends.

Does it work on mobile?

Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.

Does it work offline?

Yes, once the page has loaded. The tool keeps working with no network connection.

Does dropping a file here upload it?

No, and it does less than that: the file is not even opened. A browser gives a page the name and the type of a dropped file before anything reads its contents, and matching those two against what each tool accepts is the whole operation. You can watch the network tab while you drop one and see nothing leave.

Why does it not just convert it for me?

Because "convert" means something different for every format, and a converter that guessed would be wrong most of the time. A PDF might need to become images, text or a Word file; a HEIC might need JPG or PNG. This narrows 140 tools down to the two or three that can open what you have and lets you pick the one that matches what you are actually doing.

What if nothing matches my file?

You get told, rather than sent to a page that will fail. The formats nothing here reads are mostly the ones a browser has no decoder for: AVI, WMV, RAW camera files, older Office formats like .doc and .xls. Saving those as a modern equivalent once, in whatever made them, usually brings them within reach.

Can I convert several files at once?

Once you are on a tool, yes: the image and audio pages take a whole batch and hand back a ZIP. This page routes a single file, because it is answering "what can I do with this", and that question has one answer per kind of file rather than one per file.

Drop any file and get the tools that can open it, without uploading it.

Last updated 10 September 2026

How do I convert a file when I do not know what it is?

Drop it into filetity and it will tell you which tools can open it. The browser already exposes a dropped file's name and type before anything reads its contents, so the matching happens on those two alone: nothing is uploaded and the bytes are never touched, which means this does strictly less to your file than using a tool does. Tools naming your exact type are ranked above ones that take a wildcard, so a GIF leads with the GIF tools rather than a general image page. If nothing here can read the format you get told so instead of being sent to a page that fails.

When you would use this

Situations, not settings.

A file with an extension you do not recognise: It names what can open it without opening it, so an unknown file from an unknown sender costs you nothing to identify.
You know what you have and not what it is called here: Faster than reading 140 tool names to work out whether the one you want is called compress, resize or convert.
Checking whether this site can help before you commit: An honest empty answer is the point. A format nothing here reads says so rather than sending you to a page that fails.

How it works / no cloud

A conversion engine, not an upload form.

Nothing about the file is uploaded, and nothing is even read: the browser already knows a dropped file's name and its type, and that is all this needs. Those two are matched against what every tool on the site declares it accepts, and a tool naming your exact type is ranked above one that takes a wildcard, so dropping a GIF leads with the GIF tools rather than with a general image page. The bytes are never touched, which means dropping a file here does strictly less than using a tool does.
