Compress ODT Online
The OpenDocument format follows the same zip-of-XML design as Word, so the arithmetic is identical: markup is light, embedded media is heavy, and LibreOffice keeps full-resolution originals of every inserted picture by default. This page reclaims that decision in the browser — styles and layout untouched — and shows what the document weighs after.

Preguntas frecuentes sobre la compresión de Documents
Does compressing an ODT lose formatting?
No — styles are XML and weigh almost nothing; only the embedded images and similar assets shrink.
Will it still open in LibreOffice?
Yes, as the same format it was — the pass edits what is inside the package, not the document's format.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Compressed ODT.
What should I check before using the result?
Open the Compressed ODT in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Is Compress ODT Online free?
Yes. The compress odt online is free with no trial limit, subscription, or watermark on downloads. Use it for personal and commercial projects without creating an account.
Are my files safe when I compress online?
