Drop a file. Preview it.
Open the files your usual apps can't. Read them properly, turn Markdown into a real Word file or PDF, or check what a file is quietly carrying. Nothing is ever uploaded.
Drop your file here
Drag and drop, or choose one. It stays in your browser.
Three steps, no setup
No account, no upload, no install. Watch each step below, or drop your own file above.
Your apps give up. PreviewAny opens it.
The strange files in your downloads are usually not broken. They just need the right preview. Drop one in and see the readable version.
Markdown
Raw ## and ** become a clean, readable document.
Web pages
Angle brackets become the page itself, safely sandboxed.
Components
React files become running previews you can actually see.
Tables
Comma soup becomes a clean table you can sort and filter.
Word and Excel
Documents and spreadsheets open without Office installed.
Odd files
Images, graphics and code get a sensible preview in one place.
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.
A generator gave you one
ChatGPT, Claude, v0, Lovable or another builder 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.
Every format, one place
Markdown, web pages, components, spreadsheets, data, images and code. One tool instead of ten.
Private by design
Your file is read in your browser and never uploaded. We genuinely cannot see it.
Instant, no install
No download, no account, no waiting. Drop a file and it renders on the spot.
Save it as Word or PDF
With a Markdown file open, Save as builds a real .docx or .pdf. Headings, tables and links all still work.
See what a file is carrying
What's inside reads the part you never see: where a photo was taken, who wrote a document, comments still sitting in it. Then it hands you a clean copy.
Free, no catch
It runs on your device, so it costs us almost nothing. No signup, no card.
Nothing you drop ever leaves your computer
Most file tools quietly upload your file to a server. PreviewAny does not. Every file you drop is read and rendered right here in your browser. It is never sent anywhere, never stored, never seen by us. It is not a setting you switch on. It is the only way it works.
- ✓ No upload, no server, no copy of your file
- ✓ No account, and we never see your files or their names
- ✓ Close the tab and it is gone for good
A few quick answers
How do I open a .md (Markdown) file in my browser?
Drop the .md file into PreviewAny. It turns Markdown headings, lists, links and code blocks into a clean document, without installing a Markdown app.
Can I preview an .html file without uploading it?
Yes. PreviewAny renders local .html files in a sandboxed browser preview. The file stays on your device.
Can I open .jsx or .tsx files without a code editor?
Yes. PreviewAny can render React components from .jsx and .tsx files so you can see the component instead of only reading the code.
How do I view a .csv file without Excel or Google Sheets?
Drop the .csv or .tsv file into PreviewAny. It becomes a clean table you can sort and filter in your browser.
Does PreviewAny upload my files?
No. Files are read locally in your browser. They are not uploaded, stored, or sent to a server.
What file types can PreviewAny open?
PreviewAny supports 58 file extensions: Markdown (.md, .markdown, .mdx), Word (.docx, .doc), Excel (.xlsx, .xls), PDF (.pdf), web pages (.html, .htm), React components (.jsx, .tsx), tables (.csv, .tsv), data (.json), vector graphics (.svg), images (.png, .jpg, .jpeg, .gif, .webp, .avif, .bmp, .ico), plain text (.txt, .log), and 32 code formats including .js, .ts, .py, .sql, .yaml and .xml. Two of those are not drawn on screen: a PDF becomes a report of what it is carrying, and an old .doc gets an explanation of the free way to open it.
Is PreviewAny free?
Yes. The preview happens on your device, so there is no signup, no install and no card required.
What happens if a file cannot be previewed?
If a format is not supported yet, PreviewAny tells you clearly and, when possible, shows the raw file so you are not stuck.
Can I turn a Markdown file into a Word document or a PDF?
Yes. Open the .md file, then choose Save as. PreviewAny builds a real .docx or .pdf in your browser, with headings, tables and links intact. The file is never sent anywhere to be converted. Save as is offered for Markdown only, because both writers work from the Markdown structure the preview already reads.
How do I see the hidden information in a photo or a Word file?
Drop the file in and choose What's inside. PreviewAny reads the parts that never appear on screen: where a photo was taken and on which camera, who wrote a document and who saved it last, comments and tracked changes still sitting in it, and what a PDF is carrying. It shows you what is there, and Save a clean copy then hands back the same file with those details taken out. All the reading happens on your device, and nothing it finds is sent anywhere.
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.
