EPUB (Electronic Publication) uses reflowable ebook encoding and is best for e-readers, mobile devices, and accessible digital books. PDF (Portable Document Format) uses fixed-layout document encoding and excels at document sharing, printing, and archival with consistent formatting. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing.

Yes — archive EPUB originals before batch-converting. Re-converting from PDF back to EPUB never restores discarded data.
Seconds for typical files on a modern device; large files scale with size and CPU. Conversion speed depends on the machine, not the formats — close heavy tabs for big batches.
From reflowable ebook to fixed-layout document: quality is preserved as far as the formats allow.
A4, Letter, Book (6×9 in), or Digest (5.5×8.5 in) pages; Small 10pt, Normal 12pt, or Large 14pt Helvetica; Narrow 30pt, Normal 50pt, or Wide 80pt margins — with optional cover page and table of contents. Chapters render as plain Helvetica text (page estimate: total characters ÷ 2500), so embedded images and original fonts do not carry over.
