Frequently asked questions
- Does merging PDFs reduce their quality?
- No. The pages are copied across as they are — text stays selectable, vectors stay sharp, and embedded images are not re-encoded. A merged file is essentially the sum of its parts.
- Can I reorder the files before merging?
- Yes, and you should check it: the output follows the on-screen order, not the order you happened to select them in. Drag the cards to rearrange, and remove any file you picked by mistake.
- What happens to bookmarks and form fields?
- Page content, links and annotations are preserved. Document-level structures — the bookmark outline and interactive form fields — are not carried across, so a merged file from fillable forms becomes a flat document.
- Can I merge PDFs that are password protected?
- Not while they are still encrypted. A PDF with an open password has to be unlocked in a viewer and saved without it first; the merger reads the file directly and cannot ask for a password on your behalf.
