In-browser processing · Page previews · Flexible ordering

Review every page before combining PDFs

Instead of combining whole files blindly, you can preview every page, set the final order, and remove unwanted pages before creating the result.

Processing happens in your current browser. Files are not sent to Toolit, although very large documents may exceed your device's available memory.

Drag to reorder

Move pages from different PDFs into any final order.

Remove unwanted pages

Remove pages from the preview before building the final PDF.

Check document features

Signatures, forms, bookmarks, and other document-level features may change, so review the result.

Helpful answers before you start

How many PDFs can I merge?

The main limits are 300MB total and 250 pages rather than a fixed file count.

Can I merge password-protected PDFs?

No. Create an unlocked copy first.

Are my original files changed?

No. Toolit creates a new PDF and leaves the originals unchanged.
