Frequently Asked Questions
Can I rearrange pages while merging multiple PDFs?
Yes. After adding files, drag and drop them to change the merge order. You can also expand each PDF to drag individual pages into different positions in the final merged document.
What is the maximum file size for PDF merging?
Browser-side processing is limited by device memory. Files up to 50 MB each merge reliably on modern devices. For very large PDFs (100+ MB), use a desktop tool like Adobe Acrobat or the free PDF24 desktop app.
Are my PDFs uploaded to a server?
No. This tool uses PDF.js and pdf-lib to process PDFs entirely in your browser. Your files never leave your device — suitable for confidential documents.
Can I extract just one page from a PDF?
Yes. In Split mode, enter a single page number (e.g. page 5) to extract just that page as a standalone PDF.
Does merging PDFs combine bookmarks and table of contents?
Basic merging concatenates pages without merging bookmark structures. The output PDF will not have a combined TOC. For advanced bookmark merging, use Adobe Acrobat Pro or a dedicated PDF editor.
