Frequently Asked Questions
Q.01Will merging multiple PDFs degrade text quality or blur images?
No. FILPDF combines your files directly without recompressing or rasterizing your pages. Vector fonts, fine line art, and high-resolution photos retain 100% of their original visual sharpness.
Q.02What happens to bookmarks and internal links when PDFs are merged?
Original bookmarks and tables of contents are preserved and combined into an organized outline. Internal links pointing to specific sections are automatically re-indexed to point to the correct page numbers in the merged file.
Q.03Can I merge PDF files that have different page sizes and orientations?
Yes. PDF files support mixed page dimensions. You can combine standard A4 contracts, US Letter pages, and large landscape spreadsheets in the same document without unwanted scaling or distortion.
Q.04Are my uploaded PDF files safe and secure?
Yes, absolutely. All file transfers are protected with HTTPS/SSL encryption. We do not store, inspect, or share your documents, and all uploaded files are automatically deleted from our servers shortly after processing.
