Convert Images to PDF API

About Convert Images to PDF API

Image to PDF is a hosted API from ApyHub that converts image files, base64-encoded image data, or remote image URLs into PDF output. It exposes six POST endpoints covering three input methods (file upload, base64 string, remote URL) and two output modes (binary PDF download or a JSON response containing a signed link to the generated PDF). File- and URL-based conversions support an optional landscape parameter to control page orientation.

The upload path accepts PNG, JPEG, GIF, SVG, TIFF, and BMP formats, with a 100MB limit per request across combined files. Larger inputs are directed to the URL-based endpoint instead.

The service is intended for applications that need to produce PDFs from images without building a rendering pipeline themselves, such as assembling image-based reports, archiving receipts, or packaging visual assets for sharing and storage. It suits apps that already store images in object storage or receive them via client upload and need to convert those images to PDF as part of a document workflow.
