CoolUtils Online PDF Merger combines files into a single PDF in a browser, without signup or software installation. It accepts up to five files per pass, with a 50 MB limit for each file. The finished PDF follows the upload slots from top to bottom, and JPG, PNG, and GIF images can also be added as pages. The online tool is free. CoolUtils says uploads and downloads use encrypted SSL/TLS connections and are processed in isolated environments. It says documents are used for the merge and not stored afterward, and also says uploaded files and results are automatically deleted from its servers within 24 hours. The product page states the company's GDPR and US privacy-law commitments, while noting it does not currently advertise ISO 27001 or SOC 2 certification. The online merger does not list integrations, batch merging, or page selection. CoolUtils directs users who need recurring or folder-level jobs and command-line automation to its desktop PDF Combine product.
Who it is for
