HTML rendererAvailableStatic HTML conversion (without Pango)

Local installations need the packages listed in README.md. A detected executable is not a guarantee that every input document will convert successfully.

File handling

50 MB per request · 30 uploaded files · 200 PDF pages · 4-minute processing limit.

Inputs are deleted after successful processing; outputs are scheduled for deletion after download delivery and otherwise expire during the cleanup cron. Configure the supplied 24-hour cleanup command on your server.

Conversion quality

Complex layouts, uncommon fonts, scanned pages and damaged files may need manual review. PDF/A output should be validated with veraPDF for regulated archival workflows. Signatures are visible electronic marks; they are not certificate-based digital signatures.
