The ConvertHub API is an automated multi-format file conversion REST API supporting over 500 file format transitions across documents (PDF, DOCX, XLSX, EPUB), images (HEIC, PNG, WEBP, SVG), audio (MP3, WAV, AAC, M4A), and video (MP4, MKV, AVI, MOV). In Nigerian fintech, edtech, and legal platforms, ConvertHub automates the conversion of user-submitted iPhone HEIC photos into web-standard JPEG/WEBP formats and converts Word documents into signed PDF agreements without maintaining heavy server-side LibreOffice or FFmpeg clusters.
