Can I extract text from journal article PDFs for systematic review work?

Yes, if the PDFs contain a selectable text layer (the standard for digitally published journals). The tool extracts that text and outputs it as HTML. Scanned articles without OCR are not supported.

Will multi-column academic paper layouts convert correctly?

Text order in the output follows the PDF's internal structure, which for two-column academic papers may not match reading order. You may see column 1 and column 2 text interleaved. This is a limitation of the PDF format itself, not the tool.

Are footnotes and references included in the HTML output?

Yes — all selectable text embedded in the PDF is extracted, including footnotes, endnotes, and reference lists. Their position in the output depends on how the PDF encodes them.

How many PDFs can I convert at once?

Up to 50 PDFs per batch, with individual files up to 300 MB and a 2 GB total batch limit.

Is this tool useful for qualitative coding or NVivo preparation?

It can be a useful preprocessing step — converting PDFs to HTML gives you plain text that can be copied into qualitative analysis tools more reliably than direct PDF copy-paste. Layout won't be preserved, but text content will be.

Convert Academic PDFs to HTML for Text Access and Citation Work

Academic researchers working with large collections of journal articles, working papers, and conference proceedings frequently need text access to documents that exist only as PDFs. Copying from a PDF reader is error-prone and doesn't scale. Deliteful converts PDFs to plain HTML documents containing the extracted text, making it straightforward to search, quote, and process paper content programmatically or manually.

Systematic reviews, meta-analyses, and corpus linguistics studies all require extracting text from dozens to hundreds of PDFs. Publisher PDFs in particular often have embedded text that is difficult to copy cleanly — ligatures render incorrectly, column breaks interrupt sentences, and footnote text intrudes mid-paragraph. Converting to HTML surfaces the raw embedded text, which is often cleaner for quote extraction and keyword searching than copy-paste from a viewer.

Each PDF produces one HTML file with the extracted text wrapped in a simple document structure. Deliteful processes up to 50 files per batch at up to 300 MB per file, which covers most academic download batches. The tool is not a substitute for full-text database search, but for researchers who already have the PDFs and need the text accessible outside a PDF viewer, it eliminates a manual bottleneck.
