Frequently Asked Questions
How many PDFs can I merge at once?
There's no limit to the number of PDFs you can merge. Since processing happens in your browser, the only limitation is your device's memory. Most modern devices can easily handle 50+ PDFs.
Can I merge large PDF files?
Yes! Our tool handles large PDFs efficiently. Files up to 500MB each can be processed smoothly. For optimal performance with very large files, we recommend using a desktop computer with sufficient RAM.
Will merging reduce the quality of my PDFs?
No! By default, we preserve the original quality of your PDFs. You can optionally choose compression settings if you need a smaller file size, but even then, we use intelligent compression that maintains visual quality.
Can I merge scanned PDFs or PDFs with images?
Absolutely! Our merger works with all types of PDFs including scanned documents, image-heavy PDFs, and text documents. All content, including images, graphics, and formatting, is preserved.
Is it safe to merge confidential PDFs?
Yes, it's completely safe. Your files never leave your device - all processing happens locally in your browser. We don't upload, store, or have access to any of your documents. Your privacy is guaranteed.

Pro Tips for PDF Merging
💡 Organize Before Merging
Sort your PDFs by name or date before uploading. Use drag-and-drop to reorder files in the exact sequence you want them in the final document.
💡 Preview Pages First
Always review the page thumbnails before merging. Deselect any blank pages or unwanted content to create a cleaner final document.
💡 Use Compression Wisely
For documents with many images, use medium compression to balance file size and quality. For text-only documents, high compression works perfectly.
