Frequently Asked Questions
📊 Is there a limit on how many PDFs I can merge?
No, you can merge as many PDF files as you want. However, very large files may take longer to process since everything runs locally in your browser. For best performance, try merging files under 200 MB each.
✨ Does my file quality degrade after merging?
No. The merge tool combines PDFs page-by-page without recompressing or altering the content. Text, images, and formatting remain at their original quality.
🔒 Are my files uploaded to any server?
Absolutely not. PDForge processes your files entirely in your browser using WebAssembly. Your documents never leave your computer — there are no uploads, no servers, no privacy concerns.
📄 Can I reorder pages within the merged document?
This tool merges files as a whole. To reorder individual pages, first use the Split PDF tool to extract pages into separate files, then merge them in your desired sequence.
