CombinePDF vs Smallpdf

CombinePDF creates one downloadable PDF from uploaded PDF files and images. It accepts PDF, JPG, JPEG, PNG, and BMP files, and lets users arrange the upload order before producing the result. Image pages and PDF pages can be mixed, while JPG, JPEG, and PNG collections can be compiled into a PDF. The service is free to use without registration or an email address and says it adds no watermark. Uploads are limited to 20 files at once, with each file up to 120 MB. Uploaded files and generated PDFs are deleted when the user leaves the page; its privacy policy says files are held temporarily during processing rather than permanently. Transfers use HTTPS. The service collects usage data such as browser type, access times, and pages viewed, and uses cookies for preferences and site analysis. It runs on web, Android, iOS, Linux, macOS, and Windows.
