Overview

Merge PDF combines selected PDF files in the order you choose through the browser-local PDF worker path. The preview applies byte and page-count guards before creating the final PDF download.

Use Cases

  • Combine several small PDF documents into one browser-local download.
  • Keep source PDFs on the device while preparing a single file for sharing.
  • Validate the P0 PDF merge workflow before indexable launch state is enabled.

Limitations

  • Encrypted, corrupt, or unsupported PDFs are rejected with a sanitized error.
  • Bookmarks, form behavior, and advanced document metadata may not be preserved in this preview.
  • Input bytes, file count, and page counts are capped before output is generated.

FAQ

Does this PDF merger upload my files?
