How to Edit, Merge and Compress PDFs Free Online (No Sign-Up)
Updated · SuperPrompts
Short answer
You can merge, split, compress, convert and sign PDFs for free with SuperPrompts' PDF tools. Open the tool, drop in your file and download the result. Most of the tools process the file inside your browser, so your document does not have to be uploaded to a server, and there is no watermark.
How do I merge PDF files for free?
Open the Merge PDF tool, add your files, drag them into the order you want and download one combined PDF. The same flow works for splitting a PDF into parts or pulling out specific pages.
How can I make a PDF smaller?
Use Compress PDF to shrink file size for email and uploads. Text stays sharp; large images are reduced. If you only need a few pages, splitting first and compressing the part you need gives the smallest file.
Is it safe to edit PDFs online?
It depends on where the file goes. Tools that run in your browser keep the document on your device. Each SuperPrompts PDF tool page says whether it runs locally, so you can pick a local tool for sensitive documents.
