Pdfrender vs Api2Pdf

Api2Pdf is a conversion toolbox: one API fronting several engines, so it converts not just HTML but Office documents (via LibreOffice), and can merge PDFs — with pay-per-use pricing. Pdfrender is deliberately the opposite shape: one engine, one endpoint (POST /v1/render), one job done predictably.

When Api2Pdf is the better fit

• You need .docx/.xlsx → PDF conversion or PDF merging in the same API.
• You want to choose between Chrome and wkhtmltopdf rendering per call.
• Very low or spiky volume where pure pay-per-use beats a subscription.

When Pdfrender fits

• Your workload is HTML→PDF, full stop — invoices, reports, generated documents — and you value an API small enough to learn in five minutes.
• You want bills that never surprise you: one render costs one credit, so 100 credits/month free, then €20/mo for 10,000 credits or €80/mo for 100,000 — and credits reset each cycle (details).
• You want agents to render PDFs directly via the built-in MCP server.

FAQ

Can Pdfrender convert Word or Excel files to PDF?

No. Pdfrender is HTML to PDF only. Api2Pdf fronts LibreOffice for Office-document conversion and can also merge PDFs.

Can I choose the rendering engine per request?

No. Pdfrender is one engine, WeasyPrint, behind one endpoint. Api2Pdf lets you pick between Chrome and wkhtmltopdf per call.

Is pay-per-use cheaper than a subscription?

At very low or spiky volume, usually yes. Pdfrender's flat credit plans become cheaper and far more predictable once volume is steady.
