Questions fréquentes
Mes fichiers sont-ils envoyés à un serveur ?
Non. Chaque outil fonctionne entièrement dans votre navigateur. Vos documents ne quittent jamais votre ordinateur.
Y a-t-il une limite de taille ou de nombre ?
Aucune limite artificielle. Les très gros fichiers ne dépendent que de la mémoire de votre appareil, tout étant traité localement.
Ajoutez-vous des filigranes ?
Jamais. Le résultat est un PDF propre, sans rien d’ajouté, sur tous les outils et gratuitement.
Ai-je besoin d’un compte ?
Aucune inscription, aucun e-mail, aucun coût. Ouvrez un outil et c’est parti.
Is pdf-combiner.com really free to use?
Yes. Every tool is free, with no hidden fees, no trial that expires, and no paid tier locked behind a paywall. There is nothing to buy and nothing to upgrade. You can use all six tools as often as you like.
Do I need to install anything to use these tools?
No. Everything runs inside your web browser, so there is nothing to download, install, or update. No app, no extension, no desktop software. Just open the tool you need and start working right away on any device.
Does pdf-combiner.com work without an internet connection?
Yes, once the page has loaded. Because the tools run on your device instead of a server, you can keep working after you go offline. A connection is only needed the first time, to load the page.
What happens to my files after I close the tab?
They are gone. Your files stay in your browser's memory only while you work, and are never saved to a server. When you close the tab, that memory clears and nothing is left behind. Save any results you want to keep before closing.
Is it safe to use an online PDF tool for sensitive documents like tax forms, IDs, and contracts?
Yes. Because your files are processed on your own device and never uploaded, sensitive documents like tax forms, IDs, and contracts stay with you. There is no server copy to intercept, leak, or store. It is as private as editing a file offline.
What file formats does pdf-combiner.com support?
The tools work with PDF files across Combine, Split, Compress, Rotate, and Organize. The Convert tool also handles images: turn JPG photos into a PDF, or export PDF pages back out as JPG images.
What browsers and devices does pdf-combiner.com work on?
Any modern browser, on desktop, laptop, tablet, or phone. Because there is no app to install, the same tools work across Windows, Mac, Linux, Android, and iOS. Larger files simply depend on how much memory your device has.
How is this different from uploading my file to a PDF website?
Most PDF websites send your file to their servers to process it, then send it back. Here, the work happens inside your browser, so the file never leaves your device. You get the same result, without the upload, the wait, or a server copy.
Do you sell or share my data with advertisers?
No — not your document contents. Because they're processed in your browser and never uploaded, their contents are never sold, shared, or even seen by us or anyone else, including advertisers. We do collect limited, content-blind analytics, and, if advertising is active, share ad-related data with Google — both explained fully in our Privacy Policy.
Which tool should I use to shrink a PDF for email?
Use the Compress tool. It reduces a PDF's file size so it fits under common email attachment limits, with Light, Recommended, and Strong levels to balance size against quality. Scanned and photo-heavy PDFs usually shrink the most.
