Frequently asked questions

Yes. All conversion features are free of charge — no account needed, no hidden fees. On-page advertising keeps the service running.

Files travel over HTTPS to a third-party cloud parsing engine, then a temporary link returns the result straight to your browser. This site's servers store neither your document nor its output. Intermediate files produced during parsing follow the provider's own platform rules. As with any cloud converter, please avoid uploading highly sensitive personal information.

The upload limit here is about 100 MB per file, with a hard cap of 600 pages checked before anything leaves your device. The upstream parser may additionally enforce daily task/page quotas.

Yes. OCR (optical character recognition) is on by default, so image-only and scanned documents convert just fine. Turning OCR off can speed up plain digital PDFs.

This isn't copy-paste — an AI model analyses every page's layout, splits tables and recognizes formulas. Queue time depends on upstream load. The progress bar shows live page counts; please keep the tab open.

Formulas are exported as LaTeX expressions. Convert them with plugins such as MathType in Word, or paste into LaTeX-aware editors like Typora or Obsidian.

The .docx file is generated locally inside your browser. A failure usually means components didn't finish loading (refresh once) or memory ran low (try the standalone HTML instead).

Check in order: ① the file is a standard, unencrypted PDF; ② it opens fine elsewhere (not corrupted); ③ the daily quota isn't exhausted. If it still fails, send us the error message via the contact channel.

• Word (.docx): keep editing, commenting, re-laying-out.
• Standalone HTML: images embedded as base64 — one file that views offline anywhere or publishes directly.
• Markdown bundle: the .md plus all images, ready for blogs (Hugo/Hexo), Notion, wikis and note apps.
