Convert PDF and Office files to Markdown.
Review quality before export.

Quality check

A completed conversion can still need review.

Conversion status answers whether processing finished. The quality verdict separately tells you whether the result is OK, needs review, failed evaluation or has not been evaluated.

Image not extracted

What was found

An image from page 5 was not preserved in the Markdown result.

Why it matters

The missing image may contain information that changes how the document should be understood.

Evidence

Page 5 · present in source, absent from output.

Recommendation

Retry with image extraction enabled, or add the image manually before export.

Review mode

Review the Markdown and quality evidence before export.

Open one converted file, inspect the Markdown, source context and quality findings, then move through problem files without leaving the batch workflow.

Extraction quality depends on source

File conversion runs locally on your device.

Zlet Converter processes document files locally during the core conversion workflow. Website analytics on zlet.app are a separate data flow.

Architecture support first; stable support follows later.

Zlet Converter: common questions

Does Converter upload my files?

The core conversion flow is designed for local processing. Website analytics are a separate concern.

Is conversion success the same as quality success?

No. Conversion status and quality verdict are intentionally separate.

Can I review problem files before export?

Yes. Review mode exposes Markdown, structure and quality evidence for an individual file.

What happens when a format is unsupported?

The file remains visible with an explicit unsupported or failed state instead of disappearing from the batch.
