About OBML files
The .OBML format, which stands for Opera Binary Markup Language, is a highly specialized file type used by the Opera Mini mobile browser to save web pages for offline viewing. Originally designed for feature phones running J2ME and early smartphones, this format allowed users on slow 2G or 3G networks to store content locally without consuming excessive storage space.
The main disadvantage of the .OBML format is its heavily proprietary and binary nature. Unlike standard web formats, it is completely inaccessible to modern desktop browsers like Google Chrome or Mozilla Firefox. It requires users to maintain a specific, often outdated version of the Opera Mini app just to read their own saved data. Furthermore, because Opera's servers pre-rendered and compressed the page layout into this binary format, reversing it back to a standard web page is incredibly challenging.
Users typically need to convert .OBML files to HTML to restore standard web browser compatibility, PDF to preserve the static visual layout for archiving, or TXT to simply salvage the written content. However, be aware that dynamic elements, original high-resolution images, and complex CSS styling are often permanently lost, as they were stripped out during the initial server-side compression.
Because this is a closed, proprietary format designed specifically for Opera's proxy-rendering engine, standard online converters almost universally fail to process it. If our analysis detects a supported underlying or embedded format, viewing or text extraction may still be possible.
Convert.Guru analyzes your OBML file, detects the exact format, and lets you read the text inside.
If you want to convert OBML file to HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP, JSPX, PY, RB or PL, you can use Opera Mini or similar software from the "Offline Webpage Storage" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to OBML, try Opera Mini or another comparable tool in the "Offline Webpage Storage" category.
The OBML Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our OBML converter.
