About this tool
Ask anything about the document. Answers quote the relevant passages with page numbers. Works on this device; when the site has an AI service enabled you can switch to AI answers, which send only the relevant passages, never the file.
Your files stay on this device. SpitePDF opens and processes them inside your browser. The counter in the top bar shows how many bytes this page has sent to any server: it should read 0 B. How this works

Questions
Is SpitePDF really free?
Yes. Every tool is free with no page limits, no sign-up and no watermark.
Are my files uploaded?
No. Files are opened and processed by your own browser. They never reach a server. The only things that use the network are optional: AI answers (if this site enables them) send the question plus relevant passages of text, never the file; P2P Share and the whiteboard connect two browsers directly.
Does it work offline?
Once a tool's engine has loaded, most tools keep working without a connection. OCR downloads its language data on first use and caches it.
Is there a file size limit?
No limit is imposed. Very large files are limited only by your device's memory; on phones, split or compress huge files first.
