File Conversions API

About File Conversions API

ApyHub's File Conversion catalog offers a set of individual APIs for converting between document, image, and audio formats. Coverage includes document conversions such as Word to PDF, Excel to PDF, and PDF to Excel, image conversions such as WebP to PNG, JPEG, and AVIF, and SVG to PNG, and audio conversions such as WAV to MP3 and MP3 to AAC. A text extraction API for pulling plain text from Word documents and a video-to-GIF generation API are also included.

APIs accept input via file upload, base64, or public URL, and return either a binary file download or a signed download URL. Some operate synchronously while others (such as Excel to PDF, PDF to Excel, and GIF generation) run as trackable jobs with status and progress reporting. The catalog listing shows 78 File Conversion APIs total, accessible under a single key and bill, with individual APIs supplied by providers including ApyHub itself and FlowDocs.

This set of APIs is aimed at developers building document and media processing workflows, such as turning invoices, reports, or statements into spreadsheets, or handling image and audio format conversion within an application.
