Frequently Asked Questions (FAQ)

Will merging my PDFs reduce their visual quality?

No. Our tool performs a completely lossless merge. It copies the exact binary objects, vectors, and high-resolution image data from the source files and appends them together. There is absolutely no compression or quality degradation.

Is there a limit to how many files I can combine?

Because the processing happens within your browser's memory (RAM), there are no artificial limits or paywalls imposed by us. Most modern computers and smartphones can comfortably handle merging dozens of PDFs simultaneously.

What happens if one of my PDFs is password protected?

For security reasons, our tool cannot process encrypted or password-protected PDF files. You will need to unlock or remove the password from the individual file before attempting to merge it with others.
