In their own words
CoolUtils Online PDF Merger
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.
PDF4me Merge & Split
PDF4me Merge & Split combines PDF files in a chosen order, overlays one PDF on another, and divides documents using several rules. Splitting can produce individual pages or use page ranges, page count, barcodes, text patterns, or Swiss QR markers. Browser tools are available online without installation or sign-up, and the document features can also be used through a REST API or no-code automation. Listed connectors include Power Automate, Make, n8n, Zapier, RapidAPI, and Appy Pie. The Merge API takes an ordered array of at least two PDF files and returns the merged PDF as binary data. The free API tier has limited calls and requires no credit card. One-time packs cost $25 as a one-time purchase for 500 calls, $45, paid once for 1,000, and up to $650, paid once for 25,000 calls; calls do not expire while the account remains active. PDF4me says documents are processed in EU or US regions depending on account setup, deleted within minutes, and not retained for training. It also says files are encrypted at rest while held for processing and transfers use HTTPS/TLS.
