If you’re looking for Apryse (formerly PDFTron) alternatives for a PDF API, here are strong options depending on what you need:

Top alternatives

1. PSPDFKit

  • Strong PDF SDK/API for web, mobile, and backend
  • Great for annotation, forms, signatures, viewing/editing
  • Enterprise-grade and developer-friendly
  • Good if you need a polished document experience

2. Adobe PDF Services API

  • Official Adobe API
  • Good for PDF creation, OCR, extract, combine, protect, and more
  • Strong brand trust and reliability
  • Better for document processing than rich in-browser editing

3. Foxit PDF SDK / Foxit API

  • Competitive with Apryse in features
  • Supports viewing, editing, forms, annotations, signatures
  • Often considered a direct alternative for enterprise use

4. Sejda API / PDF.co

  • Easier to use for common PDF tasks
  • Good for merge/split/convert/compress/fill/sign workflows
  • Usually simpler and cheaper than enterprise SDKs
  • Best for lightweight automation rather than advanced UI

5. Nutrient SDK

  • If you meant Apryse’s broader ecosystem, note Nutrient is the new brand name for PSPDFKit-related offerings in some contexts, but it depends on product line. Worth checking current naming if you're comparing vendors.

6. PDFShift

  • Focused on HTML-to-PDF conversion
  • Great for generating PDFs from web content
  • Not a full editing/annotation API

7. PDFLayer

  • Simple PDF generation and conversion API
  • Good for server-side rendering of documents
  • Less feature-rich than Apryse

8. IronPDF / Iron Software

  • More .NET-focused
  • Good for generating, editing, and converting PDFs in code
  • Better if your stack is Microsoft-centric

Quick pick by use case

  • Need browser PDF editor/viewer with annotations/forms/signatures: PSPDFKit, Foxit
  • Need document processing APIs (convert/extract/OCR/protect): Adobe PDF Services, PDF.co
  • Need HTML-to-PDF generation: PDFShift, PDFLayer
  • Need .NET library/API: IronPDF, Foxit
  • Need lower-cost/simple automation: Sejda, PDF.co

What to compare

When choosing an Apryse alternative, check:

  • Annotation and redaction support
  • Forms and digital signatures
  • OCR and text extraction
  • Web viewer quality
  • Mobile SDK support
  • Licensing and pricing model
  • Self-hosted vs cloud API
  • Compliance/security needs
