Ascensio System SIA – home of the ONLYOFFICE


ONLYOFFICE is a project developed by experienced IT experts from Ascensio System SIA, leading IT company with headquarters in Riga, Latvia.
Originally ONLYOFFICE was designed for internal team collaboration.
An attempt to introduce it to a wider audience proved to be successful: ONLYOFFICE received very positive feedback from the Internet community.
As a result, its functionality was considerably revised and expanded that brought about a high and stable growth of users from different countries.
Nowadays, ONLYOFFICE is an international, open source project with employees and contributors in more than 30 countries. 
The holding company in Singapore unites our offices around the world under the ONLYOFFICE brand. For now, we have departments in Riga, Singapore, London, Dallas, Belgrade, Yerevan and Tashkent.

ONLYOFFICE Docs – the future of document processing

At Ascensio System SIA, we always keep up to date with latest technology trends and try to make an effective use of them in our work.
We were the first to build online document editors using HTML5 Canvas element. That allows us to keep ahead of our competitors providing customers with the most complete and feature-rich online office suite highly compatible with Microsoft Office and OpenDocument file formats, among others.
Introduced for the first time at CeBit, ONLYOFFICE Docs have became our pride and joy. Now you can use it as a part of our productivity suite or easily integrate into your own SaaS or on-premises solutions.
