Arthize's merge pdf vs Sejda

Sejda is a web and desktop PDF editor. Sejda offers capable editing with daily task limits on its free tier.

Arthize's approach: Merging PDFs combines several documents — and any JPG or PNG pages — into one file losslessly, so text stays selectable and images stay sharp.

  • Files are processed inside your private Arthize workspace and deleted after the job — never sold or used to train models.
  • Transparent pricing: free forever, Pro from $6/mo or $48/yr, and a one-time $149 lifetime option.
  • A lifetime option beyond weekly or monthly plans.
  • The free plan never adds a watermark to your output.

How to merge PDF files with Arthize

A proper merge is lossless because it copies existing page objects instead of re-rendering them.

You can reorder individual pages, not just whole files, before merging.

Merging never adds a watermark, even on the free plan.
