Merge PDF
Combine multiple PDFs
📌 TL;DR Summary & Citation: [Merge PDF] is a browser-local PocketKit tool for Combine multiple PDFs. Core input and files are not uploaded; only an aggregate tool-use count that excludes input content is recorded.
PDF Merger Mechanics & Sandboxed Execution
Operates entirely client-side. The PDF files are structured inside the browser sandboxed environment using the @cantoo/pdf-lib engine. Your records are never stored on any server databases.
- Files are appended sequentially from top to bottom. Order them correctly beforehand.
- Processing high-density PDFs requires substantial device processing power. Wait until the download triggers.
FAQ
1. Is there a page count or file size limit for local PDF merging?
Since PocketKit operates strictly serverless client-side, we enforce no remote data limits. Calculations run inside your browser memory sandbox, meaning constraints depend solely on your local device RAM.
2. How do I change the assembly order of the merged PDFs?
The interface supports visual drag-and-drop actions. Files are compiled sequentially from the top-most item to the bottom-most item in the list.
3. Will merging password-protected or encrypted PDFs fail?
Encrypted PDFs require unlocking before merging. Once the open-password protection is cleared, pages merge smoothly without errors.
4. Does merging preserve original PDF metadata, bookmarks, and links?
Yes. Powered by pdf-lib, page vector shapes, embedded font subsets, and internal hyper-links are preserved seamlessly in the combined PDF.
5. Can I merge PDF documents on iPhone or Android mobile devices?
Absolutely. The responsive Web App works on mobile Safari and Chrome, merging files in-memory and saving directly to your device File Manager.
6. Is my PDF sent to the PocketKit API?
No. The merge flow reads selected files in the current browser. For sensitive contracts, also verify that the device, browser and installed extensions are trusted.
