Merge PDF →Frequently Asked Questions
How many PDFs can I merge at once?
No hard cap on the count, but browser memory limits the total combined size to roughly 200MB. For larger sets, merge in batches and combine the batches.
Will the page order match the upload order?
Yes. Drag and drop to reorder before merging. The output PDF preserves the exact sequence.
Are bookmarks and links preserved?
Page-level bookmarks carry over from each source PDF. Internal links within a single source PDF stay intact; cross-document links are not rewritten.
