Choose two or more PDFs, put them in order, and download one combined file. Nothing is uploaded.
Password-protected PDFs cannot be opened. Very large files depend on your device memory. Form fields and bookmarks may not survive. Need the pages as small images instead? Try images to PDF or the image compressor.
Are my PDFs uploaded? No. Merging happens locally in your browser.
Can I merge password-protected PDFs? No. Remove the password first, then merge.
Is there a page or file limit? No fixed limit, but very large files may be slow or fail on phones with little memory.
