PDF-Dateien kostenlos online zusammenführen
Combine multiple PDFs into a single document in seconds. No software to install, no files uploaded to any server — everything happens in your browser.
Your files are never sent to our serversWarum PDFs lokal in Ihrem Browser zusammenführen?
Most online PDF mergers upload your documents to a remote server, creating a privacy risk. Our tool combines your PDFs entirely on your device — your contracts, resumes, and personal files never leave your computer.
Wie es funktioniert
1. Drag and drop your PDF files in the order you want.
2. Click Merge — the tool combines them into one document.
3. Download the merged PDF instantly. No watermark, no limits.
Warum PDF-Dateien vor dem Teilen komprimieren oder bereinigen?
PDF documents often contain hidden metadata including the author's name, software used to create the file, creation and modification dates, and even embedded comments or annotations. When you email a PDF or upload it to a website, this information becomes publicly visible.
Large PDF files can also be problematic — they exceed email attachment limits, take longer to upload, and consume more storage space. Our browser-based PDF tools compress, merge, and clean your documents instantly without uploading anything to external servers.

Welche Metadaten werden aus PDFs entfernt?
Our PDF metadata remover strips author names, company information, creation dates, modification history, software identifiers, and any embedded comments. The document content remains unchanged; only the tracking information is removed for your privacy.
Ist die Verarbeitung von PDFs im Browser sicher?
Absolutely. Unlike online PDF converters that upload your files to remote servers, our tools run entirely in your browser using WebAssembly technology. Your documents never leave your device, ensuring complete confidentiality for sensitive contracts, resumes, or personal documents.
