Merge PDF without watermark
Many “free” merge tools stamp logos on the last page or hide batch merge behind Pro. PDFTwin merges in your browser with pdf-lib — no watermark, ever — and clear batch limits instead of surprise upsells.

Open toolHow PDFTwin merge differs
Smallpdf and iLovePDF merge on their servers — fine for casual use, but files leave your device. ihatepdf merges locally with no limits. PDFTwin merges locally too, with a Free cap of five PDFs per batch (Pro unlimited) because we monetize server-heavy conversion, not organize tools.
Quick merge workflow
- Upload two or more PDFs on Merge & Arrange
- Drag documents and pages into order
- Click Merge and download — no account, no watermark
Tips for business packets
Combine cover sheet, scope, pricing, and terms before client send. Use Compress PDF afterward if email rejects the attachment size — see our email limit guide.
