Merge PDF

Combining PDFs usually means uploading sensitive documents to a random website. This merge tool stitches files together locally—cover letters with resumes, statements with receipts, or scanned pages into one packet—then downloads a single PDF.

When to use this

  • Attaching a cover page in front of an application packet
  • Combining monthly statements into one archive
  • Merging scans from different devices into a single file

Typical workflow

Add resume.pdf and cover-letter.pdf, move the cover letter to position 1 with the arrows, then merge. The download order matches your list order.

Common mistakes

  • Trying to merge password-protected PDFs without unlocking them first
  • Assuming page sizes will be normalized—each page keeps its original dimensions
  • Uploading to a cloud tool when the file contains personal identifiers you wanted to keep local

How it works

Each PDF is read in your browser with pdf-lib. Pages are copied into a new document in list order and saved as merged.pdf. Processing does not require an upload to our servers.

How to use

  1. Add two or more PDF files.
  2. Reorder with the arrows if needed.
  3. Click Merge PDFs and download the result.

FAQ

Do you upload my PDFs?

No. Merging happens in your browser. Files stay on your device.

Is there a file size limit?

Limits come from your browser’s memory. Very large scans may run slowly on older phones.

Can I merge encrypted PDFs?

Often not until they are unlocked. Remove passwords with an owner-authorized tool first.

Will bookmarks and forms survive?

Basic page content is copied. Advanced interactive features may not fully transfer.
