Merge PDF Online — Free, No Upload

Most online PDF mergers either watermark the output, cap the file count, or push you to sign up after one free use. SnapToolz doesn't — every feature is free forever, and there's no upload because the merging happens right in your browser using pdf-lib (the same library used by enterprise PDF software). Drop two or more PDFs onto the page, drag them into the order you want, and download the combined file. It's especially useful for assembling expense reports, exam documents, or contract bundles where the page order has to be exact. No size cap, no page-count cap, no nag screens.

Frequently asked questions

• Is there a limit on file count or size?

  No artificial limits. The practical ceiling is your device's available RAM — about 1GB total combined size on a typical laptop, less on phones.

• Will the bookmarks and metadata be preserved?

  The first PDF's metadata (title, author) is preserved. Bookmarks and form fields from individual files are kept in their respective sections.

• Can I rearrange pages WITHIN a PDF before merging?

  Use the PDF Organize tool first to reorder pages within a single file, then bring it here to merge with others.

• Does the output have a SnapToolz watermark?

  No. Outputs are clean — never watermarked, never altered.

• Why is this faster than [other site]?

  Because there's no upload — your file is processed right where it lives. The 'upload to server, process, download' round trip is what makes other tools slow on a phone.
