Frequently Asked Questions
How many PDFs can I merge at once?
There is no limit on the number of PDF files. You can merge 2 files or 20 files in one go. Performance depends on your device — very large PDFs with many pages may take a few seconds to process.
Will the formatting be preserved?
Yes. PDF merging combines the files at the PDF structure level using pdf-lib. All text, images, fonts, and layouts are preserved exactly as in the original files.
Can I merge only specific pages?
Yes. Enable the "Page Range" option and enter the pages you want from each file. For example, entering "1-3, 5" will include pages 1, 2, 3 and 5 from that file only.
Is there a file size limit?
No file size limits. Each individual PDF can be up to 100MB. All processing happens in your browser so very large files may take longer depending on your device's processing power.
