Our verdict on ConvertAPI
ConvertAPI is a cloud-based file conversion service for developers and businesses building document workflows. Its REST API converts more than 100 file types to PDF and converts PDFs to DOCX, HTML, JPG, PNG, PPTX, SVG, TXT, and XLSX. It also provides OCR for scanned PDFs, text and table extraction, file merging, chained workflows, and AI-powered structured-data extraction for documents such as invoices, receipts, and forms. Web and API access make it suited to applications that need conversion as an integrated service rather than a standalone desktop tool.
The published plans show a paid model with flexible consumption. Developer includes 12,000 conversions, a 200 MB maximum file size, one concurrent conversion, and self-guided onboarding. Startup raises those limits to 60,000 conversions, 300 MB, and two concurrent conversions, while adding a signed NDA and DPA plus email support. Growth and Business increase quotas, file sizes, and concurrency, with broader support options. Enterprise adds custom pricing, dedicated private servers, a guaranteed 99.95% SLA, single sign-on, 24/7/365 emergency support, and custom feature requests. There is no permanent free plan.
ConvertAPI’s main strength is breadth: inputs can arrive through URL, JSON, multipart, or streamed file requests, and workflows can chain conversions without re-uploading files. SDKs cover .NET, PHP, Java, Python, Node.js, JavaScript, Ruby, and Go, while integrations include Zapier, Make, Power Automate, n8n, and Bubble. OCR languages and recognition modes can be selected, and batch conversion is supported. Choose ConvertAPI when an application needs varied formats and document-processing features through an API. Consider an alternative if a permanent free tier or a simpler, narrower conversion tool is the priority.
