Online PDF Converter Tools
PDF is the standard format for sharing documents that need to look the same on every device — but getting a file into (or out of) PDF often means installing desktop software you'll only use once. These free browser-based converters turn Word, Excel, PowerPoint, images, HTML, and plain text into PDF, plus a couple of reverse conversions, with no software install and no signup.
Document to PDF Converters
Convert your everyday office documents straight to PDF for sharing, printing, or archiving. Use Word to PDF and Excel to PDF for the most common Office formats, PowerPoint to PDF to turn a slide deck into a shareable document, RTF to PDF and ODT to PDF for rich text and OpenDocument files, and Text to PDF for plain .txt files.
Image & Web to PDF Converters
Turn images and web pages into portable PDF documents. JPG to PDF, PNG to PDF, and WEBP to PDF combine one or more images into a single PDF file, while HTML to PDF renders a live web page into a print-ready PDF.
Word Format Converters
Not every conversion needs to end in PDF. Word to HTML converts a Word document into clean web-ready markup, and Word to ODT converts to the open-source OpenDocument format used by LibreOffice and OpenOffice.
How to Use These Tools
- Choose the converter that matches your source file type (Word, Excel, PowerPoint, image, HTML, or text).
- Upload your file — most tools accept drag-and-drop or a file picker.
- Click Convert and wait a few seconds for processing.
- Download the resulting file directly from your browser.
Usage Notes
- Complex formatting (custom fonts, embedded objects, advanced tables) may render slightly differently after conversion — always review the output before sending it on.
- For multi-image PDFs, upload images in the order you want them to appear in the final document.
- Large files may take longer to process depending on page count and file size.
Frequently Asked Questions
Is it free to convert files to PDF here?
Yes, all PDF conversion tools on this page are free to use with no signup and no watermarks added to your output file.
Will my document's formatting be preserved after converting to PDF?
Standard text, tables, and images convert reliably. Highly complex layouts or unusual fonts may shift slightly — review the PDF output before sharing anything formatting-sensitive.
Can I combine multiple images into one PDF?
Yes — the JPG to PDF, PNG to PDF, and WEBP to PDF tools accept multiple image uploads and combine them into a single multi-page PDF.
What's the difference between converting Word to PDF versus Word to HTML?
Word to PDF preserves exact print layout for sharing or printing, while Word to HTML converts content into web-ready markup for publishing on a website or blog.
Are my uploaded files kept private?
Files are processed for conversion and are not intended for long-term storage — avoid uploading highly sensitive documents to any online converter as a general best practice.
