AO-PDF

Merge PDFs

Combine 2–20 PDF files into one new document.

Local processing boundary

Current workflows process document bytes in this browser. AO-PDF records only the selected tool, outcome, duration, and coarse browser/runtime information—never filenames or document-derived data.

Selected source bytes remain separate and unchanged. Generated outputs are new files. Session history stores operation metadata only in this browser tab and never stores source filenames, document text, or hashes.

This release supports Chromium on desktop and mobile. Firefox and Safari/WebKit are unverified and unsupported.

Operating limits

2–20 files; 100 MiB per file; 250 MiB aggregate; 500 pages; 1,024 MiB estimated working-memory limit; 120-second timeout.

  • Encrypted PDFs are not supported.
  • Source metadata is not copied into the new merged document.
