Does merging PDFs reduce image or text quality?

No. Our client-side PDF engine copies the original page streams directly into the new combined container without re-encoding text or downsampling embedded images.

How many PDF files can I combine at once?

You can merge as many PDF files as your device memory supports—typically dozens of documents up to 100 MB per file—without any artificial restriction.

Can I merge PDFs with different page sizes and orientations?

Yes. Each page retains its original dimensions and portrait or landscape orientation inside the merged PDF file.

Is this Merge PDF tool free for commercial and office use?

Yes. All PixelsKits PDF tools are completely free for personal, academic, and commercial use with zero watermarks.
