How to open a PDF file

  1. Choose your file

    Tap “Choose a file” above, or drag your .pdf file anywhere onto this page.

  2. Read it instantly

    DocuFun opens it on your device in a second or two. Nothing is uploaded.

  3. Print, save or share

    Use Print to make a PDF, search inside the document, or download the original again.

Never uploaded

Your file is opened by code running in this page. It never travels to a server — not ours, not anyone’s.

Works offline

After your first visit DocuFun keeps working with no connection. Try it in airplane mode.

No sign-up

No account, no email, no cookies, no tracking. Open a file and read it. That’s it.

PDF questions

Can I edit, merge or sign PDFs here?

DocuFun is for viewing. Our sister site PdfNext has free in-browser PDF tools.

Is it safe to open private documents here?

Yes. The file is read by code in this page and never leaves your device. DocuFun has no server that could receive it.
