Your files stay here

Every tool on UnlimitedPDF runs entirely in your browser. PDFs and images are read with the File API, processed with client-side libraries (including WebAssembly workers), and offered back as a download. They are never uploaded to our servers — because this app has no file-upload endpoint.

Optional sign-in (Google or X) is for an account only. It is not required for any tool, and signing in does not send your documents anywhere.

Privacy-respecting analytics (Vercel Analytics) may record which tool page was opened. They do not receive filenames, file contents, or document text. Ads, when shown, are labeled and never stand between you and a download.

Some engines (PDF.js worker, optional OCR language data) are loaded as static assets or from a public CDN the first time you use that tool. Those requests do not include your files.

Browser memory is the only practical size limit. If a very large file fails, that failure happens on your device.
