Frequently asked questions

Does merging change original PDF content?
Merging combines files in sequence but does not alter source text. Compression may reduce image quality depending on level chosen.
Can I compress without merging?
This tool is optimized for merge plus compress workflow. For single-file optimization, upload one PDF and apply compression.
Will bookmarks and links be preserved?
Basic page content is preserved, but advanced metadata/bookmarks can vary by source structure and PDF generation method.
What compression setting should I choose for print?
Use low or medium compression for printed copies so scanned diagrams and signatures remain clear.
Can I upload password-protected PDFs?
Encrypted PDFs may need unlocking before processing. Remove password protection first if the upload fails.
