- Professional Sharing: PDFs are universally supported and look the same on every device, making them the standard for sharing documents professionally.

What our customers say
People love how great our product works and how we're always there to help
"Business pressures now demand almost a 24x7 operation. The difference between choosing one SaaS product or another isn't just down to the technical capabilities of each, but down to their responsiveness when it doesn't quite work. In this case, an issue blocked us from being able to use the platform as intended. Within minutes of using the live chat, the issue was not only reproduced but correctly identified. Within the hour, the hot fix had been coded, tested and applied - unblocking the bottleneck and allowing us to carry on working. This is exceptional and the reason why I can't recommend this company enough - I'm so impressed and very grateful for their hard work. Keep it up!"
"This is a clever idea, especially in concert with programmatic (AI-generated) SEO."
"We were looking for tools to help our users create and edit images with templates. We tried options like Canva, but Templated.io turned out to be the perfect choice for our product. It offers an easy API to render images, and its embed editor lets us provide our users with a full editing experience without having to create complex frontend components. It's a really great tool!"
"We integrate Templated.io into our portal for custom flyer generation. The editor is amazing, and the Canva import tool is exactly what we were looking for. Massive shoutout to Pedro for the technical support. He responds incredibly fast and fixes issues in no time. Highly recommended!"
"Brilliant piece of software. Reasonably priced (vs Canva's outrageously expensive API), and despite a few intricacies with the editor, a really fully-featured document generation API. Really great support too from Pedro, the founder!"
"Very reliable platform. Almost no errors ever. Easy to setup templates and use the API. And AMAZING support!"
"We booked the "Scale" package to use it as a "print product editor" and we are amazed by the features and the support! Pedro replies to every question and also implemented small hints to the API for better functions on our request. Absolutly great Software and Service!"
"Templated.io is basically a an API-first graphics content designer which makes it super easy to programmatically create document and image assets. It has most basic features and it is robust and "just works". The Make.com app really makes it super simple to incorporate into automation workflows. What sets templated.io apart the most is Pedro and his super fast and service minded, solutions oriented responses."
"Amazing API, perfect support and a lot of new features on a monthly basis."
"Currently working through an implementation of Templated.io and the customer service has been spectacular!!! I get near immedate response and near immediate remedies. It's glorious. I wish other companies were like this!!! Strong recommendation!"
