Merge PDF FAQ
Is merging PDF files online free?
Yes, PDFForge is 100% free. There are no limits, fees, or demands for an account — unlike cloud PDF merge services that restrict file counts on free plans.
Are my PDFs safe when I merge them online?
Yes. PDFForge processes files entirely in your browser using WebAssembly. Your documents are never uploaded to a server, so nothing is stored or transmitted.
Can I merge PDFs and images together?
PDFForge combines multiple PDF files. To merge images with PDFs, first convert your images to PDF with the JPG to PDF or PNG to PDF tool, then merge the resulting files.
