Doczilla's answer:
At Doczilla, we embarked on a mission driven by necessity. Faced with the challenge of converting HTML into polished documents and images, we scoured the landscape for a solution that aligned perfectly with our needs. Surprisingly, we found none that matched our specific use case.
Our platform is our response to this gap. We've designed a fully managed API dedicated to simplifying the creation of PDFs and screenshots.
