Does merging PDFs reduce text sharpness or quality?

No. pdf-lib copies original PDF page objects directly without rasterizing, preserving crisp vector text and graphics.

Can I merge password-protected PDFs?

Encrypted PDFs with owner/user locks must be unlocked before client-side page copying can read their page tree.

How many PDFs can I combine at once?

As many as your browser memory comfortably handles—dozens of standard documents merge in under a second.

Can I remove blank pages after merging?

Yes, open the merged output in our Split PDF tool to extract exact page ranges.

Fast, Lossless PDF Merging in Your Browser

Combining separate PDF proposals, appendices, and cover sheets shouldn't require installing bloated desktop suites or trusting random upload sites with confidential paperwork. ToolCix's Merge PDF tool executes entirely in browser RAM using pdf-lib.

Because pages are copied structurally rather than re-rendered as images, every font, selectable paragraph, and vector diagram stays razor-sharp.
