Is this PDF merge tool free?

Yes, this PDF merger is completely free with no signup, no ads, no watermarks, and no usage limits. You can merge unlimited PDF files without any account creation or subscription. The tool runs entirely in your browser using client-side JavaScript, so your documents are never uploaded to any server. There are no hidden fees, premium tiers, or quality restrictions.

Are my PDF files uploaded to a server?

No. All PDF merging is performed 100% locally in your browser using the pdf-lib JavaScript library. Your files are never uploaded to any external server, cloud service, or third-party platform. Documents remain on your device throughout the entire process. This ensures complete privacy and security for sensitive, confidential, or personal PDF files. No signup required.

Can I reorder PDF files before merging?

Yes, you can easily rearrange the order of uploaded PDF files by moving them up or down in the list before generating the merged document. The final PDF will follow your specified page sequence exactly. You can also remove individual files from the queue. This free browser-based tool requires no signup and keeps all your documents completely private.

Is there a file limit for merging PDFs?

There is no fixed file count limit imposed by this tool. The practical capacity depends on your device's available browser memory and processing power. For most users, merging dozens of standard-size PDFs works smoothly. Very large files (hundreds of MB) may require more device resources. This free tool requires no signup and processes everything locally for privacy.

Will merged PDF quality change?

No. The tool copies original PDF page data directly into the merged document without any re-rendering or recompression. This means page quality, fonts, images, and vector graphics remain completely unchanged and identical to the source files. The merged PDF preserves 100% of the original content quality. Free to use with no signup, ads, or watermarks.
