PDF merge & compress

Combine PDFs in order, or re-save one PDF for modest space savings—bytes stay in your browser.

Pick multiple PDFs; pages are appended in the order your browser lists them (usually selection order).

Combining documents without a desktop app

Merging PDFs is useful when you want invoices, chapters, or scanned pages in one file instead of several. It can save time before sharing a packet with a client, submitting a form bundle, or organizing reading material into a single document.

Compression has limits

Browser-side compression can help reduce file size when a PDF contains redundant structure or overly large assets. It will not magically solve every scanned archive, though, so treat the output as a practical reduction rather than a guaranteed dramatic shrink.

Merge workflow

Combine invoices, chapters, or scanned pages in the order you select. Reordering before merge saves a second pass in desktop tools.

Compression expectations

Browser-side re-save can shrink some PDFs by dropping redundant objects, but scanned image PDFs need dedicated OCR or image compression tools for big savings.

Local PDF processing

Select PDF files from your computer to merge in order or re-export for modest compression. pdf-lib runs entirely in the tab — contracts and invoices stay off remote servers.

Limits

Very large PDFs or many scanned image pages may be slow or produce limited size reduction compared to desktop prepress tools.

Quick start

  1. Add PDF files — Select one or more local PDFs to merge or re-save.
  2. Choose merge or compress — Combine documents in order, or re-export to reduce file size modestly.
  3. Download output — Save the result — files are processed with pdf-lib entirely in your tab.
