Merge PDF

Concatenate several PDFs into a single file you can submit, archive, or share as one packet.

Applications, tax packets, and reading lists often arrive as many small PDFs. This merger stitches them into one document so reviewers open a single attachment instead of a zip full of parts.

Page order matters—name files clearly and arrange them before you export. Encrypted or corrupted sources may fail until you unlock or repair them in a dedicated PDF utility.

If you only need a subset of pages from a large binder, split first, then merge the pieces you want. Keep originals; merged output is a new file.

How to use

Gather the PDFs — Collect every file that should appear in the final packet.
Upload in sequence — Add files to the tool and drag to set the correct order.
Preview the stack — Confirm first pages of each section look right before merging.
Merge and download — Create the combined PDF and save it with a clear packet name.
Spot-check page count — Open the result and verify no section is missing or duplicated.

Use cases

Job or school applications — Combine resume, cover letter, and certificates into one upload.
Client deliverables — Ship proposals plus appendices as a single PDF.
Personal records — Archive yearly statements into one chronological file.

Tips

Unlock password-protected PDFs before merging if the tool cannot prompt for each file.
Huge image-only scans make large mergers—compress scans upstream when possible.
After merging, bookmarks may not rebuild automatically; add outlines if needed in a full editor.
Sensitive packets: delete temporary downloads from shared computers.

FAQ

Is there a file limit?

Practical limits depend on browser memory and total size. Very large books may need desktop software.

Do my PDFs upload to a server?

Merging is designed to stay in the browser when possible so documents remain on-device.

Can I rotate pages while merging?

Focus is concatenation and order. Rotate in a PDF editor if pages are sideways.

What about forms and signatures?

Interactive features can flatten or behave differently after merge—test before legal submission.

Need only some pages?

Use split-pdf first, then merge the excerpts.

split-pdf complements this workflow; image tools help when scans need cleanup first.
