Why merge PDFs online instead of desktop software?

Desktop tools like Adobe Acrobat can be expensive and slow to install. Doclair gives you the same result instantly in your browser — no installation, no subscription, no compromise on quality.

Is it safe to merge confidential PDFs online?

Unlike older tools that upload files to remote servers, Doclair uses WebAssembly technology to process everything locally. Your files never leave your device — 100% safe for legal, medical, and business documents.

Merge PDFs on iPhone and Android

You don't need a dedicated app. Doclair works in mobile Safari and Chrome. Tap the upload button, select files from your Files app, and merge on the go.
