Questions from the bench
- Are my PDF files uploaded to a server?
- No. PDFup processes files locally in your browser, so your PDFs stay on your device. All processing happens 100% locally in your web browser and your files are never uploaded to any server.
- Is PDFup really free?
- Yes, it is completely free with no catch. There are no hidden fees, no subscription plans, no usage limits, and no premium-only features. All tools are 100% free to use with no file limits, no sign-ups, and no watermarks.
- Do I need an internet connection to use PDFup?
- After loading the website for the first time, most tools will work completely offline because all processing libraries are loaded into your browser. You can disconnect from the internet and continue to merge, split, compress, and edit PDFs securely.
- Are there any file size or usage limitations?
- No artificial limits are imposed on file size, the number of files, or how many times you can use a tool. The only limitation is the processing power and memory of your own computer, as very large or complex files may take longer to process.
- What technology does PDFup use?
- PDFup is built on modern web technologies using JavaScript libraries like PDF-lib.js and PDFKit.js compiled to run efficiently in your browser via WebAssembly, enabling powerful server-like processing without data leaving your device.
