- Pueden vender o analizar los metadatos de tus documentos

- Imposible de hackear - tus datos se quedan contigo

🔒 Perfecto para documentos sensibles: Informes financieros, registros médicos, contratos legales, datos comerciales confidenciales
Frequently Asked Questions
Is it safe to merge PDFs online?
Yes! PDFCombiner processes your files entirely in your browser. Your PDFs never get uploaded to our servers or anyone else's. Everything happens locally on your device. Learn more in our complete guide →
How many PDFs can I merge?
There's no limit! Merge as many PDFs as you want. The only constraint is your browser's memory, which can typically handle dozens of files.
Do I need to create an account?
No! PDFCombiner is completely free and doesn't require any registration or login. Just visit the site and start merging.
What happens to my files after merging?
Your files are immediately removed from browser memory after you download the merged PDF. We don't store or keep any copies.
Can I select specific pages from each PDF?
Yes! Click the "Pages" button next to any file with multiple pages to select specific pages. You can choose exactly which pages to include in the merged PDF, eliminating the need to split files first.
Can I merge large PDF files?
Yes! PDFCombiner can handle large files, but processing time depends on your device's capabilities. For best performance, we recommend keeping total file size under 100MB. Very large files may take longer to process and consume more browser memory.
What keyboard shortcuts are available?
PDFCombiner supports keyboard shortcuts for faster workflow:
- Ctrl+O (or Cmd+O on Mac) - Open file selection dialog
- Tab - Navigate through interactive elements
- Enter or Space - Activate buttons and open file picker
- Arrow Keys - Navigate through file list when focused
Does this work on mobile devices?
Yes! PDFCombiner works on mobile phones and tablets. The interface is fully responsive and optimized for touch interactions. You can select PDFs from your device and merge them on the go.
Can I merge password-protected PDFs?
No, password-protected PDFs cannot be processed. You'll need to remove the password protection from your PDFs first before merging them. This is a security feature to respect file encryption.
Will merging PDFs reduce quality?
No! PDFCombiner preserves the original quality of your PDFs. Pages are copied exactly as they are without compression or quality loss. Text, images, and formatting remain intact.
Which browsers are supported?
PDFCombiner works in all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version of your browser for the best experience and performance.
What file formats are supported?
PDFCombiner works exclusively with PDF files (.pdf). If you have documents in other formats (Word, images, etc.), you'll need to convert them to PDF first before merging.
How to merge PDFs on Mac without Adobe?
PDFCombiner works perfectly on Mac! Simply open this website in Safari, Chrome, or any modern browser, drag and drop your PDF files, and click "Merge PDFs". No Adobe Acrobat or Preview app needed. Everything happens right in your browser, making it faster and more private than traditional desktop software.
How to merge PDFs on Windows 10/11 for free?
PDFCombiner is completely free on Windows 10/11 with no installation required! Open this website in Edge, Chrome, or Firefox, select your PDF files, and merge them instantly. Unlike Windows' built-in PDF tools which are limited, PDFCombiner offers page selection, bookmarks preservation, and works entirely offline after the page loads.
Can I merge PDFs on iPhone/iPad?
Yes! PDFCombiner works on iPhone and iPad using Safari or any mobile browser. Simply visit this website, tap the file upload button to select PDFs from your Files app, iCloud Drive, or other sources, then merge them. The interface is optimized for touch and works great on mobile devices. You can even add PDFCombiner to your home screen for quick access.
How to merge PDFs and keep hyperlinks?
PDFCombiner automatically preserves hyperlinks, bookmarks, and internal links when merging PDFs. External links (URLs) and internal document links remain clickable in the merged output. Our bookmark preservation feature also ensures that table of contents and navigation structures are maintained across the merged document.
Can I merge PDFs with forms and preserve form fields?
Yes! PDFCombiner preserves interactive form fields (text fields, checkboxes, radio buttons, dropdowns) when merging PDFs. The form fields in each document remain functional in the merged output, allowing recipients to fill them out. However, note that field names should be unique across merged documents to avoid conflicts.
Will annotations and comments be preserved?
Yes! Annotations, comments, highlights, sticky notes, and markup from your original PDFs are preserved during the merge process. All collaborative notes and review comments remain visible in the merged document, making it perfect for consolidating reviewed documents while maintaining the feedback.
How does PDFCombiner compare to Adobe Acrobat?
PDFCombiner offers a focused, privacy-first alternative to Adobe Acrobat for PDF merging:
- 100% Free - No subscription fees (Acrobat costs $19.99-$29.99/month)
- Privacy First - All processing happens in your browser, files never uploaded
- No Installation - Works instantly in your browser, no software to download
- Page Selection - Choose specific pages from each PDF before merging
- Cross-Platform - Works on Windows, Mac, Linux, and mobile devices
While Acrobat offers more advanced features for professional workflows, PDFCombiner excels at fast, private, and free PDF merging for everyday use.
Can I use PDFCombiner for commercial purposes?
Yes, absolutely! PDFCombiner is free to use for both personal and commercial purposes. There are no licensing restrictions, usage limits, or fees.
