Merge PDF

Combine documents in your preferred order.

Files are processed in your browser without uploads. The combined limit is 50 MiB and 200 pages per operation.

Encrypted PDFs are unsupported. Keep the original and review the result. Previews never run PDF links, attachments, or scripts.

PDF support limits for this operation

Processing limits: 50 MiB and 200 pages; 15 seconds per job. Decoder capacity: 32 MiB per stream and 64 MiB cumulative, with object-count and nesting limits. These are not a bound on total browser memory. Page information and export may remain available when a particular encoding cannot be previewed.

Ordinary links, annotations and AcroForm fields belonging to retained pages are preserved, without flattening forms or rasterizing pages. XFA export is unsupported. A page graph referencing the document catalog or page tree is rejected because copying them could reimport pages outside the output. Editing invalidates digital signatures. Original files are unchanged.

One document with an ordinary form can be merged with documents without forms. Merging multiple documents with interactive forms is unsupported because field resources and names can conflict; forms are not silently discarded.
