Frequently Asked Questions
Is it safe to merge files here?
Yes. innoPDF processes PDF and supported image files locally in your browser, so they are never uploaded to our servers. Your privacy stays protected throughout the process.
Can I reorder files before merging?
Yes. You can drag PDF or image file cards into any order before merging. This is useful when you need a custom document sequence or a final PDF in a specific order.
Can I combine PDF documents that have different page dimensions?
Yes. Each page preserves its native orientation, scale, and paper dimensions (e.g. mixing Letter and A4 pages in one file).
Can I mix image files together with PDFs in a single merge?
Yes. innoPDF accepts JPG, PNG, and WebP images alongside PDFs, rendering image cards as full pages directly in your merged document.
