Frequently asked questions
- Can I merge PDFs without uploading them to a website?
- Yes. This tool runs entirely in your browser with JavaScript, so your PDF data is not sent to SheetRender or another processing server. You should still follow your organization’s policies when handling sensitive documents.
- Is there a limit on how many PDFs I can merge?
- There is no fixed file-count limit, but each file can be up to 100 MB and the selected files can total up to 200 MB. Each source and the merged result can have up to 5,000 pages. Browser memory still varies, so large batches work best on a desktop or laptop.
- Will the merged PDF keep the original quality?
- The visual page content is copied without intentionally re-rendering or watermarking it, so text and images generally retain their quality. Document-level features such as bookmarks, attachments, metadata, and some interactive form behavior may not carry into the newly built PDF.
- Do I need an account or have to pay?
- No account, no payment, no watermark. The tool is free because it costs us almost nothing to run. Your browser does the work, not our servers.
- Can I control the page order?
- You control the file order. Use the arrows to arrange the list before merging, and pages appear in that order. To pull out or drop specific pages first, use the extract pages tool, then merge the results.
Need one PDF per spreadsheet row?
Merging is handy when a batch of PDFs needs to travel as one file. If you are on the other side of that problem (one spreadsheet that needs to become many separate, personalized PDFs), that is what SheetRender does. It designs a template from one example document and renders a polished PDF for every row.
