Does this tool work as part of an automated ETL pipeline?

Currently the tool operates through the Deliteful web interface, not an API. It fits best as a manual preprocessing step for batch document loads — upload a batch, download the HTML, then feed your automated pipeline. For fully automated extraction, it handles up to 50 files per batch.

What is the output structure of the HTML files?

Each output is a basic HTML document containing extracted, HTML-escaped text. There are no external dependencies, scripts, or complex markup — just text in a standard HTML wrapper, predictable across all conversions.

How does this compare to running pdfminer or Apache Tika locally?

For simple embedded-text extraction from clean PDFs, the output quality is comparable. The advantage is removing the library dependency from your pipeline environment entirely — no installation, versioning, or maintenance. The trade-off is that it's a web-based batch tool rather than a programmatically callable library.

Will PDFs generated by print-to-PDF from web pages convert well?

Generally yes — browser-generated PDFs embed text reliably and convert cleanly. PDFs from CAD tools, specialized software, or heavily formatted documents may have less predictable text order.

Is there a per-file size limit that would affect large document ingestion?

Individual files can be up to 300 MB, with a 2 GB total per batch. Most document sources in ETL work — reports, filings, product docs — are well within this range. Very large PDF books or document bundles may need to be split first.

Convert PDF Sources to HTML Text for ETL and Text Processing Pipelines

ETL pipelines that ingest document sources — policy libraries, product catalogs, research archives, regulatory filings — routinely hit a hard stop when those sources are PDFs. Text extraction from PDFs is a solved problem in theory, but in practice it introduces a dependency (Poppler, pdfminer, Tika) that has to be maintained, versioned, and deployed alongside the pipeline. Deliteful handles the extraction step externally and outputs HTML — a format your pipeline can ingest without a PDF-specific dependency.

For ETL work, the value of the PDF-to-HTML conversion is not the HTML structure — it's that text is extracted, HTML-escaped, and available in a flat file your ingestion stage can read without a specialized library. One PDF in, one HTML file out, with predictable naming. The batch endpoint handles up to 50 files at once (300 MB per file, 2 GB total), which fits well into an incremental load pattern: stage new PDFs, run a conversion batch, ingest the resulting HTML files, repeat.

The tool's explicit limitations are also useful constraints for pipeline design: no OCR, no layout preservation, no image extraction. If your pipeline receives scanned PDFs, you'll need an OCR stage upstream. If it receives digitally created PDFs — the common case for regulatory filings, product documentation, and system exports — the embedded text layer is extracted cleanly and the HTML output is ready for the next stage.

How it works
