About Merge PDF
Merge multiple PDF files into a single document entirely in your browser. Drag and drop your PDFs, reorder them by dragging thumbnails, then click merge. The tool uses PDF-lib running locally in your browser to combine the files client-side without any server upload. Useful for combining scanned documents, consolidating reports, or assembling multi-chapter ebooks. Supports PDFs of any page count and file size (limited only by device memory). The merged PDF preserves bookmarks, metadata, and embedded fonts from the source documents. Download the combined file immediately after processing.
Frequently Asked Questions
Can I reorder the PDFs before merging?
Yes. Drag the file thumbnails into your desired order before clicking Merge.
Is there a limit to how many PDFs I can merge?
No server limit applies. The practical limit is your browser's available memory.
Are bookmarks and links preserved?
Yes. Internal bookmarks and hyperlinks from source documents are retained in the merged output.
