What it is
CoolUtils Online PDF Merger combines multiple files into one PDF in a browser, without signup or software installation. The free tool accepts up to five files per pass, with a limit of 50 MB per file. The order of the upload slots determines the sequence in the merged document. JPG, PNG and GIF images are accepted as well, with each image becoming a PDF page. CoolUtils says uploads and downloads use encrypted SSL/TLS connections and are processed in isolated environments. The product page says documents are used for merging and are not stored afterward; CoolUtils also says uploaded files and converted results are automatically deleted from its servers within 24 hours. The listed platform availability includes Android, iOS, Linux, macOS, web and Windows, though the primary platform is web. The online page does not list integrations, batch merging or page selection. CoolUtils recommends its desktop product for recurring or folder-level work and command-line automation.
