Convert documents, spreadsheets, ebooks, emails and archives in your browser
Sooner or later every file lands in the wrong format: a Word file that has to be plain text for a form, a spreadsheet that an app only accepts as CSV, an OpenDocument file from a government office, an ebook for an old Kindle, an Outlook message you need to keep as a record, or a folder you have to send as one ZIP. These free converters handle those jobs without installing anything. Start with DOCX to TXT, Markdown to DOCX, XLSX to CSV, CSV to XLSX or ODT to DOCX.
There are ebook converters such as EPUB to MOBI and Markdown to EPUB, contact and calendar converters (VCF to CSV, CSV to ICS), email tools such as EML to MSG, a ZIP creator and a ZIP extractor that also opens RAR and 7z, and web-page tools: webpage screenshot, webpage to image and webpage to Markdown. Converters that produce or read PDFs, such as DOC to PDF and EPUB to PDF, are in PDF Tools; JSON, XML and YAML converters are in Developer Tools.
Files are converted inside your browser and are not uploaded. The web-page tools are the exception by necessity: the page address is fetched by our server, because browsers cannot read other websites directly, and the optional AI clean-up sends only the page’s text blocks. Old Office formats (DOC, PPT, RTF, ODT, ODP) use LibreOffice running in your browser, a one-time download of about 78 MB that is cached afterwards.
Which converter do you need?
- Need plain text? DOCX to TXT, EPUB to TXT, Markdown to TXT and Email to TXT keep paragraphs, lists and tables readable instead of running everything together.
- Sending a spreadsheet somewhere? Most systems import CSV; choose UTF-8 with a byte-order mark if the file will be opened in Excel, so accented letters and ₹ survive.
- OpenDocument vs Microsoft Office? ODT, ODS and ODP are the native formats of LibreOffice and many governments; DOCX, XLSX and PPTX are Microsoft’s. Both directions are here, with a report of anything that cannot carry over.
- Contacts or calendar moving to a new phone or app? Use the VCF and ICS converters; they understand Google and Outlook export layouts and time zones.
- Saving a web article? Webpage to Markdown or Text keeps just the article; Webpage Screenshot captures it as it looks.
Tips for clean conversions
- Keep the original. Converting between formats can drop features the target does not support, such as charts in CSV or styles in plain text.
- Check numbers and dates after converting a spreadsheet: day/month order and leading zeros (phone numbers, PIN codes) are the usual surprises, and the converters show the choices they made.
- For ebooks with copy protection (DRM), use the store’s own app; these tools detect protected files and explain rather than open them.
- Very large files depend on your device’s memory; a computer handles hundreds of MB more comfortably than a phone.
File Converters: frequently asked questions
Are my files uploaded?
No. Documents, spreadsheets, ebooks, emails, contacts and archives are read and written inside your browser. Only the web-page tools fetch the page you name through our server, and the optional AI clean-up sends that page’s text blocks.
Why does DOC to PDF download 78 MB first?
Old Word, PowerPoint and RTF files are complex binary formats that only a full office suite reads reliably, so these converters run LibreOffice inside your browser. It downloads once, after you agree, and is cached for next time.
Will formatting survive?
Text, headings, lists, tables and images usually do. Features the target format lacks are dropped and listed in the result — for example charts when saving a spreadsheet as CSV, or CSS styles when making a MOBI ebook.
Can I convert several files at once?
Most converters accept a batch and give you a ZIP of the results, keeping the original file names.
Do the converters work on phones?
Yes, in current mobile browsers. The LibreOffice-based tools need a browser that supports cross-origin isolation (Chrome, Edge, Firefox); Safari shows a lighter alternative where one exists.
Which formats are not supported?
Password-protected and DRM-protected files are detected but not opened. AES-encrypted ZIP and encrypted RAR or 7z archives cannot be extracted. For Apple Pages and Keynote, export to DOCX or PPTX in the app first.
