Free Document Converter: No Sign-up, and Nothing Is Uploaded
This document converter is free, needs no sign-up or login, and does not upload your files. Contracts, essays, notes and reports are read and rebuilt inside your browser, so they never leave your device, and no watermark is added to the result. Add a file, choose the format you need and download it.
It works between PDF, Word (DOCX), OpenDocument Text (ODT), Rich Text Format (RTF), Markdown, HTML, plain text and LaTeX. A document can also become an EPUB or FB2 e-book, and a PDF can be turned into one image per page as PNG, JPG, WebP or SVG, or into slides in a PPTX file. An HTML page with tables can be turned into XLSX, CSV or JSON.
Be realistic about what a conversion can keep. Text, headings, lists, tables, links and images carry over, but complex layout such as columns, floating shapes and exact page design is simplified. The tool tells you when a pair is layout-simplified, so you can decide whether the result is good enough.

About the formats
About PDF
PDF is a fixed-layout format created by Adobe and standardised as ISO 32000. It looks the same on every device, which is why it is the usual format for finished documents, and it is hard to edit. Converting a PDF to an editable format means extracting its text and images and rebuilding them as a simple flow, so columns, forms and exact positions are not reproduced.
A scanned PDF is only a picture of a page, so it contains no text to extract. Converting it to DOCX or TXT will give you little or nothing. Such a file needs text recognition, which this converter does not do.
About DOCX, ODT and RTF
DOCX is the default Microsoft Word format since Word 2007, a ZIP of XML files. ODT is the word-processing format of LibreOffice and OpenOffice, an open ISO standard. RTF dates from 1987 and holds text with basic formatting, and it opens in almost every word processor.
Between these three, headings, lists, tables, links and images are kept, while complex layout is simplified. If you need to open a Word file in LibreOffice, ODT is the natural target, and RTF is a fallback for very old programs.
About Markdown, HTML and plain text
Markdown is plain text with light markup for headings, lists, links and emphasis, created by John Gruber in 2004 and widely used for notes and documentation. HTML is the markup of web pages and keeps links, tables and images. Plain text has no styles, images or layout, and it is the smallest way to store words.
Conversions among Markdown, HTML and text are the simplest in this category. Converting anything to plain text keeps only the words, so formatting and images are dropped.
About LaTeX
A TEX file is the source of a LaTeX document, widely used in mathematics and science. Only the basic structure is converted: headings, text, lists and tables. Custom macros, packages and typeset equations are not reproduced, so do not expect a perfect copy of a thesis.
PDF to images, slides and e-books
Converting a PDF to PNG, JPG or WebP gives one image for each page, and SVG gives one vector file per page. Converting a PDF to PPTX gives one image slide per page, so the text on those slides is not editable. A document converted to EPUB or FB2 keeps content and headings, but the page layout is replaced by text that reflows to the screen.
HTML tables to spreadsheets
An HTML file with tables can be turned into XLSX, CSV or JSON, where each table becomes rows and columns. This works for tidy tables and is less reliable for pages that use tables only to arrange layout.
Privacy: how it works
- Your documents stay on your device. The page reads each file with the browser's file API, converts it with code running in the tab, and hands the result back as a download. No upload happens, so there is no copy of your file on our servers to protect, delete or leak.
- There is nothing to sign up for and no login. The converter does not ask for an email address, and it does not need to know who you are to do its job.
- You can check the claim yourself: open your browser developer tools, watch the Network tab while a file converts, and you will see no request that carries your file.
- Documents are often the most sensitive files people own: CVs, contracts, medical letters and tax papers. They are processed in your device memory and handed straight back as a download, so no server ever holds a copy. Close the tab when you are done and the working data is gone with it.
Tips
- Send a PDF when the layout must not change, and send DOCX when the other person needs to edit.
- Convert from the original editable file when you have it, not from a PDF made from it.
- Check tables, footnotes and images after converting, because complex layout is simplified.
- For notes and web publishing, convert to Markdown or HTML, which any text editor can open.
- If a PDF comes out empty as text, it is probably a scan, and no tool without text recognition can read it.
- Use plain text when you only need the words, for example to paste into an email.
- Keep the original file until you have looked through the converted one.
- Pick EPUB when you want to read a document on an e-reader, since the text reflows to fit the screen.
Frequently asked questions
Is it really free?
Yes. There is no price, no trial, no credit card and no watermark added to your results. Ulkaa Tool does the conversion with your own device, so there is no server bill to pass on to you.
Are my files uploaded?
No. Your documents are read and converted inside your browser and are never sent to Ulkaa or to anyone else. The result is created on your device and you save it from there.
Do I need an account?
No. There is no sign-up and no login. Open the page, add your files and convert. An Ulkaa account is not needed for anything on this tool.
Is there a file size limit?
No limit is set by us. The real limit is your device: the conversion uses your own memory and processor, so very large files can be slow, and a very big batch may need to be split into smaller runs.
