Will P.

Software Developer

“Liked heavy daily use of the API inside their product, excellent support and testing through the web interface. Found the interface confusing at first, though they adjusted quickly.”

Giuseppe C.

CTO

“Liked replacing several file APIs with one covering PDF repair, optimization, email to PDF and OCR, plus temporary storage for chaining tasks. Found thumbnail generation support unclear and wanted it added.”

David M.

Integration Specialist

“Liked how easy the service was to use and its Zapier integration. Found the account stopped after 23 of 250 free conversions with an undisclosed time limit, so plan terms felt unclear.”

Mariel Jenine A.

Student

“Liked support for many file formats, easy integration with existing systems, reliability and responsive support. Found the free tier limits conversions and file sizes, and large files process slowly.”
