Frequently Asked Questions
How do I merge PDF files for free?
Simply upload your PDF files above. You can see every page as a preview, drag them into the desired order, rotate individual pages, or delete ones you don't need. Once ready, click 'Export PDF' to download your merged file.
Is it safe to merge PDFs on Utilon?
Yes, Utilon uses client-side processing. Your files are never uploaded to our servers, making it safer than traditional online PDF tools. All operations happen directly in your browser.
Can I reorder individual pages from different PDFs?
Absolutely! Our advanced engine extracts every page from the uploaded PDFs, allowing you to mix, match, and reorder them exactly how you want.
Is there a file size limit?
The limit depends on your browser's memory and your plan (Free users up to 10MB, Pro up to 100MB). For merging many large files, we recommend our Pro plan.
