Is the document to PDF converter free?

Yes, completely free — no account, no subscription, no hidden cost. Convert as many files as you need.

Is my file safe? Will it be stored on your server?

Your file is uploaded only to our own server for conversion — it is never sent to any third party. The file is permanently deleted immediately after your PDF download is complete. We do not read, index, or keep any copies of your document. If that server is temporarily unavailable, the job moves to our own backup server in Korea — still not a third party. In that case your file and the finished PDF are held only until you download them, and are cleared automatically within 30 minutes.

Is the formatting kept in the PDF?

Yes. The server-side engine reproduces fonts, tables, images, headers, footers and margins faithfully — including multi-column text, embedded charts and spreadsheet print ranges. Custom fonts that are not embedded in the file may render differently.

What is the file size limit?

30 MB per file, which covers the vast majority of office documents including image-heavy ones. If your file is larger, remove images or split the document before converting.

Does it work on mobile?

Yes. It works on any device with a modern browser — iPhone, Android, tablet or desktop. Open the page, upload your file, download the PDF. No app to install.

Which file formats can I convert to PDF?

Word (.docx, .doc, .rtf, .odt, .txt), Excel (.xlsx, .xls, .csv, .ods), PowerPoint (.pptx, .ppt, .odp) and Hangul (.hwp, .hwpx). One file at a time, up to 30 MB.

Can I convert HWP to PDF without Hancom Office?

Yes. The conversion runs on our server, so nothing needs to be installed on your machine — the same applies to Word, Excel and PowerPoint files.

Can this turn a PDF back into Word or Hangul?

No. This tool converts documents into PDF, not the other way round. For the reverse direction we currently offer PDF to Image only.

📄 Document to PDF — Word, Excel, PowerPoint and HWP, free

Convert Word, Excel, PowerPoint, Hangul (HWP) and OpenDocument files to PDF in seconds — completely free. One page handles every office format, so you do not need a different site for each one.

Converting a document to PDF turns an editable file — Word (.docx), Excel (.xlsx), PowerPoint (.pptx) or Hangul (.hwp) — into a fixed-layout PDF that looks identical on every device and is not easily edited.

To convert, your file is sent to our own server and deleted right after — not a third party.

How your file is handled. This tool needs server processing: your file is sent over an encrypted connection (HTTPS), processed, and deleted right after — it is never stored.

About

Toolio's document to PDF converter runs a professional server-side engine (LibreOffice/Gotenberg) that preserves fonts, tables, images, headers, footers and page layout. Unlike browser-only tools that struggle with complex formatting, server-side rendering handles even heavy documents precisely.

Supported input: Word — .docx, .doc, .rtf, .odt, .txt · Excel — .xlsx, .xls, .csv, .ods · PowerPoint — .pptx, .ppt, .odp · Hangul — .hwp, .hwpx. Hangul files convert without Hancom Office installed, which is what most people outside Korea need and what most Korean users no longer have a licence for.

One file at a time, up to 50 MB. Your file exists on the server only for the few seconds the conversion takes and is permanently deleted as soon as the PDF is ready. We never read, index or share document contents.

How to use

Click "Choose File" or drop your document — Word (.docx, .doc, .rtf, .odt), Excel (.xlsx, .xls, .csv, .ods), PowerPoint (.pptx, .ppt, .odp) or Hangul (.hwp, .hwpx).
Press "Convert to PDF". The file is sent to our server and rendered with LibreOffice.
Wait a few seconds — larger or image-heavy files take a little longer. If our server is down, the job moves to a backup server and takes a minute or two.
Your PDF downloads automatically. The uploaded file is then deleted and never kept.
