Looking for a pdf2htmlEX Alternative?
pdf2htmlEX has no commercial support and no active maintenance roadmap. BuildVu is commercially supported, actively developed, and integrates into the same server infrastructure.
The problem with pdf2htmlEX
pdf2htmlEX works well enough for straightforward documents and it's free to use. The problems surface when it doesn't:
- No commercial support. When a document breaks or renders incorrectly, there is nobody to contact and no guarantee of a fix.
- No active maintenance roadmap. The project has no commercial backer. Bug reports pile up with no commitment to resolution.
- Build and dependency issues on modern systems. pdf2htmlEX requires a specific set of system libraries and does not build cleanly on current Linux distributions or on Windows without significant setup work.
- Complex documents expose its limits. Non-Latin character sets, embedded fonts, complex layouts — the output regularly diverges from the original, and there is no commercial incentive to fix it.
If your documents are simple and the pipeline is not in production, these are manageable. If it is, they're not.
What BuildVu provides instead
BuildVu is a commercial PDF-to-HTML/SVG library developed and maintained by IDRsolutions. It has been in active development for over ten years.
Guaranteed support
Submit a problem file and the development team investigates it. Fixes ship in the next release, not in an issue tracker that nobody reads.
Regular releases
New builds every six weeks. Daily pre-release builds are available if you need a fix before the next release.
Runs anywhere
Java library with no external system dependencies. Runs on Windows, Linux, and Mac. No system libraries to patch, no Docker required (though Docker is also supported).
Handles complex documents
Non-Latin characters, embedded fonts, annotations, mixed content. These are the cases where pdf2htmlEX typically falls over.
How much does your integration need to change?
Both pdf2htmlEX and BuildVu produce HTML from PDF. The main integration difference is how you call them: pdf2htmlEX is a command-line binary; BuildVu is a Java library, a Docker microservice, or a cloud API endpoint.
BuildVu's output uses the same page-based or single-file structure. Text is real text, not SVG paths. Fonts are extracted and converted for the web. If you have a viewer or parser that consumes pdf2htmlEX output, the format mapping is close.
In 2026, one customer told us they migrated their entire system in a single day.
Deployment options
- Java library: embed directly in your application, data stays on your server
- Docker microservice: run as an API endpoint on your own infrastructure
- Cloud API: use IDRsolutions' hosted service for lower-volume use cases
For teams with data privacy requirements (security, legal, AI), the self-hosted options mean documents never leave your infrastructure.

"We found BuildVu, [and the software was] recommended by the technical team who had made a prototype using the free trial."

"The biggest thing [for easy evaluation] was being able to have access to a trial and see if this was going to work for us. That was hugely important."
