**APIs profiled:** 4

Sejda provides online and desktop tools for editing and manipulating PDF documents - merge, split, compress, convert, edit, watermark, OCR, and fill forms. Its only documented hosted REST API is the HTML-to-PDF conversion API at api.sejda.com; the broader merge/split/OCR task set is delivered through the web and desktop apps and through the open-source Sejda SDK and sejda-console (Java, AGPLv3), not a hosted task API.
