Stop Solving PDF Problems.
Hand Them to Us.
Get back to building what matters. Set it up once, forget about it, find it still working six months later.
Join developers who stopped wrestling with Puppeteer, wkhtmltopdf, and broken PDF libraries
Sound Familiar?
These problems cost development teams weeks every quarter.
PDF generation fails in production
Works locally, breaks in CI. Fonts missing, layouts shifting, timeouts on complex pages.
Text extraction returns gibberish
Merged words, lost tables, garbled Unicode. Hours spent cleaning up what should be clean data.
Your team is debugging instead of building
Every edge case is a rabbit hole. New PDF library version, new set of problems.

--output invoice.pdfReal Results from Development Teams
Self-hosted PDF generation typically takes 3-12 seconds. A dedicated API brings that under a second — users actually wait for sub-second responses.
No more debugging headless Chrome crashes, font rendering bugs, or memory leaks. One REST call replaces an entire PDF infrastructure stack.
Three OCR engines — Tesseract for speed, DocTR for accuracy, Claude Vision for complex layouts — so you pick the right tool for each document.
