Does Zamzar support OCR for scanned PDFs?

No. Zamzar does not include OCR (optical character recognition). If your PDF is a scanned image, Zamzar will produce an EPUB with embedded images but no selectable text. For scanned PDFs, use a converter with built-in OCR like toolkit.bot.

What EPUB version does Zamzar output?

Zamzar typically outputs EPUB 2, not EPUB 3. EPUB 2 is an older standard that lacks HTML5, MathML, and WCAG accessibility features. For accessible publishing or modern e-reader features, EPUB 3 output is preferred.

Is Zamzar free for PDF to EPUB conversion?

Yes, Zamzar has a free tier that allows conversions up to 50 MB with a daily limit. The free tier requires entering your email address to receive converted files. Paid plans add API access, larger file limits, and faster processing.

How does Zamzar handle two-column PDF layouts?

Poorly. Zamzar reads text sequentially across both columns, which breaks the reading order for academic papers and multi-column documents. Sentences jump between columns mid-phrase. A converter with layout detection handles this correctly.

Is Zamzar safe to use for confidential documents?

Zamzar's privacy policy states they delete files within a day of conversion. For highly confidential documents (legal, medical, financial), check their current privacy policy and data processing terms before uploading. If privacy is a concern, a local conversion tool is a safer option.

Zamzar's PDF-to-EPUB Quality on Different Document Types

Simple single-column text documents

Zamzar performs reasonably well here. Text extracts correctly, basic heading structure is preserved, and the output is usable on e-readers. This is probably 80% of use cases and Zamzar handles them fine.

Academic papers (two-column)

Two-column academic PDFs are where Zamzar consistently fails. It reads text column-by-column instead of recognizing the layout, which results in sentences jumping between columns mid-word. The output is unreadable. toolkit.bot handles this with layout detection.

Scanned PDFs (image-only)

Zamzar does not include OCR. A scanned PDF — where pages are images, not text — will produce an EPUB with embedded images but no searchable, selectable text. toolkit.bot runs automatic OCR on image-only pages.

Documents with tables

Table handling varies. Zamzar often renders tables as plain text or loses structure entirely. For documents where tables matter (financial reports, comparison charts, data tables), the output requires manual cleanup.

When to Use Zamzar vs toolkit.bot

Use Zamzar if: you need to convert many different file formats in one place, you're okay with email delivery, and your PDF is simple single-column text
Use toolkit.bot if: your PDF is scanned, academic (two-column), has complex tables, or you need WCAG 2.2 AA accessible EPUB3 output

Zamzar Pricing (2026)

Zamzar offers a free tier with limits on file size and daily conversions. Paid plans start around $9/month and add API access, larger files, and priority processing. For bulk conversion or API automation, both Zamzar Pro and toolkit.bot's API are worth comparing.

Bottom Line

Zamzar is a reliable general-purpose converter with a long track record. For simple PDFs it works. For anything with OCR needs, two-column layouts, or accessibility requirements, a dedicated converter like toolkit.bot will produce significantly better EPUB output.
