Merge PDFs
Combine PDF files in your chosen file order. Up to 25 PDFs, 100 MB and 500 pages combined.
PDFs up to 100 MB and 500 pages total. Merge up to 25 files. Image-based compression: up to 100 pages. Files are processed on your device.
Extract: use 1-3,5,8 to choose pages in that order; leave blank for all pages. Split: separate output groups with semicolons, for example 1-3;4-6;7,9. Leave blank to make one PDF per page.
Image-based compression replaces each page with a JPEG image. It removes selectable/searchable text, links, annotations and accessibility tags. Image quality is reduced. Keep your original. Large pages are scaled down to stay within browser memory limits.
