EPUBTurn and pdf2ereader: compare a real research PDF

By EPUBTurn · Updated

On the same published paper, EPUBTurn’s reviewed export kept passage order and numeric context; pdf2ereader mixed the columns and omitted Figure 1’s plots. EPUBTurn’s figure crop still has a limitation.

The real paper used for this comparison

A browser converter that advertises no document upload may fit strict handling rules. In this permitted paper trial, however, pdf2ereader’s default output mixed columns and lost Figure 1’s plots. EPUBTurn’s reviewed result preserved the reading order and useful panels. Processing permission and observed reading quality remain separate decisions.

We publish EPUBTurn. The comparison uses the source and saved results so you can inspect the evidence.

How the EPUBTurn result was made

EPUBTurn’s initial automatic workflow stopped on page 7. Three equation image boundaries were manually corrected before a reviewed result was made. Competitor files use their stated defaults. The remaining figure defect was not repaired.

Column order: a value enters the wrong sentence

pdf2ereader’s tested default output inserts “16.82–18.96; n = 57 sites” into the opening left-column passage about young mature female fish. In the source, that interval belongs to a result at the end of the left column and continuation at the top of the right. The words survive, but their interleaving interrupts the explanation. The screenshot and raw reading order are evidence for that specific problem.

Figure 1: caption words are not the plot

The source combines a world map, density curve and scatterplot, each with meaningful markers and legends. pdf2ereader’s output retains caption and label text but not those visual panels. Numbers and a figure caption cannot replace the relationships visible in the plots. Compare the source page beside the downloaded figure passage before calling a chart retained.

What EPUBTurn retained—and what was clipped

EPUBTurn’s reviewed reading sequence keeps the left-column explanation together and places the numerical continuation with the proper result. Unlike pdf2ereader’s caption-only passage, the Figure 1 image contains the map and both plots. Its lower x-axis titles and ticks are clipped. Keep the PDF for those labels rather than accepting an incomplete graphic as complete.

Choose a permitted workflow, then judge its content

pdf2ereader advertises browser processing without document uploads. We did not audit that privacy claim. EPUBTurn uses cloud processing, so document-handling permission comes before a reading-quality choice.

Browser captures use a 1280 × 900 view at 100% zoom. No native reader or device was tested. This paper has no scan or table-grid test; no accuracy or speed ranking is claimed.

The source, raw files and your next check

Source: Hadj-Hammou et al. (2024), Global patterns and drivers of fish reproductive potential on coral reefs, Nature Communications 15:6105, doi:10.1038/s41467-024-50367-0. CC BY 4.0. We used original pages 1–10, omitting the final reference/licence page. No source wording was rewritten. Converted files and screenshot excerpts are adaptations.

Start with permission to process the document. If cloud processing is allowed, check an EPUBTurn sample for coherent paragraphs and useful pictures. If uploads are prohibited, pursue a permitted local workflow instead. The automatic sample contains up to ten pages, so unselected figures still need a later check.
