Convert ODS to PDF
Ethical Tube's free ODS to PDF converter turns ODS spreadsheets into PDFs, the universal format for sharing documents, using LibreOffice, the open-source office suite. It runs entirely in your browser, so your spreadsheets are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the LibreOffice engine (77 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
ODS and PDF at a glance
What is an ODS file?
ODS is the OpenDocument spreadsheet format, the default in LibreOffice Calc and an open ISO standard. Excel and Google Sheets open it, though some formatting and advanced formulas may not carry over exactly. It opens in LibreOffice Calc, Apache OpenOffice, Microsoft Excel, and Google Sheets.
What is a PDF file?
PDF is the standard format for sharing documents that should look the same everywhere. It fixes the layout, fonts, and images of every page, which is great for reading and printing but makes editing hard. A PDF can contain real text or only scanned pictures of pages. It opens in every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Good to know
What changes when you convert ODS to PDF
- LibreOffice lays out the pages, so text, images, tables, headers, and footers look like they do in the original.
- Each sheet is printed on as many pages as it needs, using the print areas and page setup saved in the workbook.
- Fonts that aren't built in are replaced with similar ones, which can shift line breaks slightly.
- The first conversion downloads LibreOffice compiled to WebAssembly (77 MB). It's cached, so later visits start quickly.
- Chinese, Japanese, and Korean text may appear in a fallback font.
- Password-protected documents can't be converted.
- It works best on a computer, because LibreOffice needs a lot of memory.
FAQ
Questions, answered
Is this ODS to PDF converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with LibreOffice compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Will my PDF look like the original ODS file?
In most cases, yes. LibreOffice lays out every page, including fonts, images, tables, headers, and footers. If the document uses fonts that aren't built in, similar fonts are used, which can shift line breaks slightly.
Why is there a download the first time?
The conversion uses LibreOffice, the open-source office suite, compiled to run inside your browser. It's about 77 MB, downloads once from Ethical Tube's own server, and is cached for next time. Your documents are never uploaded.
Can I convert several ODS files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each PDF file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
It works in Chrome, Edge, Firefox, and Safari, but it's built for computers. LibreOffice needs about 1 GB of memory, which many phones can't spare.
What can open a PDF file?
Every browser, Adobe Acrobat Reader, macOS Preview, Microsoft Edge on Windows, phones, and Google Drive.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and most computers handle documents with hundreds of pages.
