Frequently asked questions
Are my files uploaded to your server?
No. All processing happens inside your browser using JavaScript (pdf-lib, pdf.js, Tesseract.js). Your files never touch our servers, and we have no way to access them.
Is it really free? What about watermarks?
Every tool is free to use without limits or watermarks. We make money from non-intrusive ads on the page, not from your files.
Do I need to install anything?
No. PDF2atom works entirely in your browser. There is nothing to download or install.
What is the maximum file size?
Limited by your browser memory (typically several hundred MB). For best performance, keep individual PDFs under 50 MB.
Does it work offline?
Once the page is loaded, most tools work offline (since processing is local). The page itself needs an internet connection to load the first time.
