A handful of ways to combine PDFs without opening a paid suite: PDF Stitcher joins several PDFs into one, Photos to PDF stacks a camera roll into a single document, and Replace PDF Pages swaps specific pages in from another file. PDF Batch Compiler goes further, merging one CSV row at a time into a filled template — one output PDF per row.
Files are combined right in the browser tab, so nothing is queued on a remote server and there's no forced account or watermark. Built for students stitching lecture PDFs together, admins assembling contracts, and small-business owners fixing a page in an existing document without redoing the whole file.
Every tool runs in your browser — no upload, no account, free.
