About this converter

Keep TXT, MD, MARKDOWN files in the same format while you clean, format and transform them locally in the browser.

What happens to your file

For supported tools the file is read with the browser File API and held in memory on your device. It is validated, processed by the Text and subtitle codecs engine in a Web Worker, and the result is handed back as a download. At no point is the file sent to a server.

What to expect from the output

The tool writes TXT, MD, MARKDOWN, HTML, HTM, JSON, CSV, XML, YAML, YML, RTF, LOG. Formats differ in what they can represent, so expect simple structure to transfer reliably while detailed layout may be simplified by the target format.

How to use this converter

Four steps, none of which involve an account.

  1. 1 Choose your file

    Drop a txt, md, markdown, html, htm, json, csv, xml, yaml, yml, rtf, log file onto the drop area or browse for it.

  2. 2 Check the output

    The output format is preselected as TXT. Change it if the tool supports other targets.

  3. 3 Convert

    Everything happens on your device, so speed depends on your machine rather than a queue.

  4. 4 Download

    Save the result, then reset the tool to clear it from memory and start again.

Frequently asked questions

Answers specific to Find and replace.

Is this tool free?

Yes. Find and replace is free to use and needs no account, no sign-up and no email address.

Where is my file processed?

This tool is being built for local processing, so the file is handled by your own browser. Until that engine is connected the page shows an explicit notice instead of pretending the conversion succeeded.

Which files can I use as input?

Accepted formats are TXT, MD, MARKDOWN, HTML, HTM, JSON, CSV, XML, YAML, YML, RTF, LOG. The converter writes TXT, MD, MARKDOWN, HTML, HTM, JSON, CSV, XML, YAML, YML, RTF, LOG.

Will my formatting be preserved?

Simple text, headings, lists and tables transfer reliably. Complex page layout, columns and embedded objects depend on the target format and may be simplified, so check the result before relying on it for print or submission.

Why do some document tools need a download and others do not?

Text and markup tools — Markdown, HTML, plain text and the text utilities — use parsers the browser already has, so they run instantly. Word, OpenDocument, EPUB and PDF files are containers that must be unpacked and understood, which needs a layout engine that is fetched only on those tools.

Do you support legacy .doc files?

Yes. Legacy binary Word files are read by the document engine. The newer DOCX and ODT formats are converted with higher fidelity because they are structured archives rather than a single binary blob.

Are the text utilities safe to use on any text file?

Yes. Formatting, cleaning, normalising, line-ending, encoding, case, find and replace, and counting all operate in place and keep the original file format, so a Markdown file stays Markdown.
