Why combine PDFs into one file?
Sharing or submitting several related PDFs — a contract split into parts, a set of scanned pages — is usually easier as a single file. Unedited pages keep their original text and quality; nothing gets flattened into an image unless you've actually edited that page.
Supported formats
This page defaults to combining everything you drop in into one PDF — untick "Combine into one PDF" in the bulk panel to get separate files instead, or pick PNG, JPG, WEBP, or ICO if you don't want PDF at all.
Frequently asked questions
Does this preserve the original PDF quality, or does it just take a picture of each page?
If you haven't cropped, resized, or recolored a page, its original content — including selectable text — is copied directly into the combined file. Only pages you've actually edited get rasterized.
Can I combine PDFs with different page counts?
Yes — every page from every PDF you drop in becomes its own entry in the file list, in order, ready to combine into one.
Are my images uploaded to a server?
No. Every conversion and edit happens locally in your browser using the Canvas API and JavaScript. Files never leave your device.
