stop staring at files you can't open.

Drop a file.
See what it is.

Drop a .md, an .html page, a code component or a .csv. The files your everyday apps can't open, or that turn to gibberish. See them rendered instantly.

Who it's for

If you've ever been handed a file you couldn't read

You don't need to be a developer. You just need to see what's in it.

📨

Someone sent you a file

A developer or colleague shares a .md README or an .html mockup and it looks broken on your machine.

🤖

An AI tool gave you one

ChatGPT, Claude or a builder like v0 hands you a file, and the moment you save it, the formatting falls apart.

You found an old one

A folder full of files with cryptic names and no memory of what each one was. Drop it in and see.

Good to know

A few quick answers

Do I need an account?

No. Drop a file and see it. No signup, no card, ever.

What files can it open?

.md, .html, .jsx, .tsx, .txt, .json, .csv and images. We're adding new formats and features all the time, so it's worth dropping back in to see what's new.

Can you see my files?

No. Your file never leaves your device. It's rendered right here in your browser, and we never upload or store it.

Why is it free?

Previewing happens entirely in your browser, so it costs us almost nothing to run. No catch.

What if a file won't open?

Most of the time it just works. If we can't render something yet (the size, the format, anything), we'll say so plainly and show you the raw file, so you're never stuck. We add new formats regularly, so it's worth checking back soon.

Does it work on my phone?

Yes. It runs in any modern browser with no install. Drop or pick a file and it renders.

How it started

Born from a folder full of files I couldn't open.

AI tools kept handing me .md, .html and .jsx files, and my computer either showed raw code or offered to open them in apps made for developers. There was no simple, native place to just see them. So I started building one. PreviewAny is chapter one.
