The Codecon Summit is one of the main IT events for developers held annually in Brazil. It brings together innovation, technology, coding and fun, and features content geared toward the careers of both novice and experienced developers.

In 2026, the Codecon Summit will be a two-day event taking place on August 14 and 15, 2026, in Pinhais/PR, in the metropolitan region of Curitiba.

As a silver sponsor, ONLYOFFICE will have a booth at the event venue where you will have a chance to meet our representatives in person.

Hey everyone! We have been chatting with some of the interns who have worked with us this year. Their stories are worth a read if you are curious about what it's actually like to intern at an open-source company.

• Moncif Meftah is a PhD student in English Literature who ended up working on our Arabic localization, including DocSpace and the form template library. He summed up the experience as "challenging, flexible and insightful." Full interview
• Shashank Jha came in from a finance background in India and joined as a technical writing intern, keeping our Help Center guides and GitHub READMEs clear and accurate. He even represented us at DevConf 2026, and built his own Claude AI workflows to speed things up. His three words were "enriching, autonomous and professional." Full interview

Two very different paths — literature and finance — both landing in open source.

For anyone who didn't know, our Internship Program started back in 2024 and covers everything from localization and documentation to development and design.

Hey everyone! With the back-to-school season here, our team put together a blog post specifically for schools and universities in Brazil, and I wanted to share it with the community.

If you are in Brazil, you probably already know about the new EDCA law (Lei nº15.211/2025), which came into force in March. It sets strict rules around protecting kids' data online, and it has made schools check whether their software actually complies.

The good news is that ONLYOFFICE is a good choice for Brazilian schools and universities:

• Self-hosting so all student and teacher data stays on your own servers, fully under your control;
• Open-source code on GitHub that anyone can audit — no hidden data collection, no behavioral profiling;
• PT-BR localization, so the whole interface (and the blog posts too) is in Brazilian Portuguese;
• Real-time collaboration for group assignments and shared class materials;
• Integrations with Moodle, Chamilo, OpenOlat and other e-learning platforms you might already be using.

Basically, it's built with privacy in mind from the ground up, which lines up nicely with what the law now requires.

Want to know how ONLYOFFICE helps non-profits across the globe? Below is a use case from Germany featuring FILMZ e.V., a volunteer-run film culture organization that promotes film culture and holds events for cinema lovers in Mainz throughout the year.

Some peculiarities of their ONLYOFFICE setup:

• Software continuity across team members. ONLYOFFICE was adopted years ago by people who've since moved on. New volunteers just pick it up and keep going with no relearning curve.
• Spreadsheets run the festivals. From film selection to the full schedule, everything is tracked and written in ONLYOFFICE Spreadsheet Editor.
• Real-time collaboration via HumHub. The team co-edits office files on the go and is now moving to the Enterprise license for better mobile editing.

As Jo Bernhard from FILMZ puts it:

>For our work at FILMZ – from the smallest meeting notes to creating the festival schedule – ONLYOFFICE has become indispensable. Our film culture work is seen by our audience mainly on the screen in the cinema, but without the many gears turning in the background, for which ONLYOFFICE provides an important foundation, our work would be unthinkable.

At ONLYOFFICE, we continue celebrating our 16th anniversary, looking back at the moments that shaped our journey. In our series of special blog posts, we revisit the ideas, decisions and milestones that helped transform a small collaboration platform into the office suite for millions of users worldwide:

• The year we went open source
• Digital learning and what ONLYOFFICE has to do with it
• The integration ecosystem story
• Partners who scaled with us
• From requests to reality: the features that shaped ONLYOFFICE
• 16+ countries, one team
• Born in 2009, still independent: what that means for your office in 2026
• 8 things we got wrong (and how they made ONLYOFFICE better)

Explore all the posts on our blog.

What started as an internal collaboration tool built by our team at Ascensio System SIA in Riga, Latvia, is now a full open-source office suite used by 21+ million people around the world.

16 years is a long time in software. A lot of projects don't make it anywhere near that. So it feels worth stopping for a second to say thanks to everyone who's been part of our incredible journey — the contributors, the bug reporters, the people who kept nagging us about that one feature until we shipped it and, of course, the Reddit community.

Here is a short write-up on 16 special things we would like to share with you on our birthday.

I know some of you have been here way longer than me, so drop your ONLYOFFICE stories below. Would genuinely love to read them.

Happy birthday, ONLYOFFICE 🥳

Celebrating 16 years of ONLYOFFICE, we continue our series of blog posts telling you stories about our project. Below is a story about how format compatibility shaped the ONLYOFFICE editors from the very beginning.

ONLYOFFICE didn't start out with native OOXML support. Back in 2009, it was an internal collaboration platform called TeamLab that relied on an OpenOffice plugin — heavy, unreliable and hard to maintain.

By 2011, after a lot of internal debate, our team made a decision to adopt DOCX, XLSX and PPTX as core formats. The reasoning was straightforward: that's what most people were already using.

Other milestones:

• The intermediate format phase (2012–2013). For a while we used internal temporary formats (DOCT, XLST, PPTT) that converted back to OOXML on save. By 2013, we dropped that entirely and moved to native OOXML editing.
• The format list kept growing intentionally. Over the years we added ODF templates, WPS Office formats for Chinese users, Google Drive formats, macro-enabled OOXML variants and more. Each addition had a specific user need behind it.
• PDF became a first-class format. We launched our own PDF editor in 2023, switched fillable forms to PDF in 2024 (dropping our OFORM format to improve cross-app compatibility) and added password-protected PDF editing in 2026.
• Recent additions show the same philosophy. Apple iWork and Hancom HWP/HWPX support arrived in 2025 to serve macOS and South Korean users. TSV and Markdown saving came in 2026 for data and technical writing workflows.

Hey everyone! We wanted to share some news with the community before it kicks off: we're teaming up with our partner SpaceNet AG at GITEX AI Europe 2026 in Berlin, and we'd love to meet any of you who are planning to attend.

The whole idea behind this collaboration comes down to something a lot of you already care about: digital sovereignty.

A quick intro to SpaceNet AG

For those who haven't come across them, SpaceNet is a German IT service provider based in Munich, operating since 1993. They run their own data centers in Germany, and their whole approach is built around keeping organizations in full control of their data, applications and digital workplaces.

Where to find us

If digital sovereignty, compliance and operational reliability are on your radar, come say hi. Ask us anything, watch a live demo or just chat about what sovereign collaboration could look like for your setup.

• Date: June 30 – July 1, 2026
• Venue: Messe Berlin, Berlin, Germany
• Stand No: H1.2-27

The ONLYOFFICE API 9.4 is now available. If you develop integrations or automations involving documents, there are some changes you’ll want to know about:

• Croatian is now supported as an interface language.

• Plugin debugging should be easier thanks to better command logging.
• You can now block specific plugins from loading in controlled setups.
• Plugins get better cursor control for guided form completion.
• Document merging is now supported, which is great for reports, contracts and batch document workflows.
• Signature forms are more flexible for automated document processes.
• Spreadsheets received a big upgrade for working with structured tables, sorting, ranges and generated reports.
• Improvements for spreadsheet autofill, formulas, paragraph inspection and editor cleanup.

Overall, the release introduces lots of small things that should make integrations smoother.

For anyone running Plone with the Volto frontend, we've just released the first version of our connector. Here is what you can do within this integration:

• Create new files directly in Plone: documents, spreadsheets, presentations and PDF forms, all from the Contents section without leaving the interface;
• Open files for viewing, editing or reviewing: the review mode uses Track Changes, so collaborators can suggest edits without touching the original text;
• Edit PDFs and fill out PDF forms: text editing, annotations, page management, OCR and support for forms with checkboxes, dropdowns, text fields, etc.;
• Convert files and download them: pick a format from the dropdown, convert, done;
• Configure everything from Site Setup: including a demo server option if you want to try it before setting up your own ONLYOFFICE Docs instance.

Format support right now: DOCX, XLSX, PPTX and PDFs. The connector is free and open-source — you can find it on GitHub and the npm Registry.

If you use Mendeley for citations inside ONLYOFFICE, there's a new plugin update that fixes a lot of the friction points people have complained about.

Here's what this updated brings to ONLYOFFICE users:

• Context menu citation editing: you can now right-click a citation and edit it directly, no need to reopen the full panel every time;
• Prefixes, suffixes, and locators: add things like "see p. 42" or "cf." right in the citation settings;
• Omit Author: this option hides the author name when you've already mentioned them in the sentence, which keeps citations cleaner;
• Ibid. support: repeated citations are now handled automatically for footnote-based styles;
• Custom CSL styles: you can upload your own .csl file if your institution or journal has specific formatting requirements;
• Better bibliography formatting: more options to keep reference lists consistent;
• Improved Word compatibility: citation formatting holds up better when going back and forth between ONLYOFFICE and Word.

The interface was also redesigned to make navigation less clunky overall.

If you're a student, researcher or part of an academic team that collaborates on papers, this update is probably worth your time. The plugin is free — you can grab it through the Plugin Manager on the Plugins tab.
