Your files are your files.

Fold PDF is a free browser tool operated by ksana-opc. Your PDFs and filenames are processed on your device, without an account or file upload.

Documents and downloads

We read only the files you select or drop into the page. They are used to create previews and a merged PDF in this tab. The app does not send documents, filenames or your output filename to a server. It does not store them in localStorage, IndexedDB or a database.

Clear all removes the selected file and preview references. Reordering, removing or adding files invalidates the old result. Closing or reloading the tab ends the session. Downloads you save remain on your device and are under your control.

Website requests

Cloudflare hosts the website and its code, rendering resources and fonts. Ordinary requests can include IP address, browser information, requested path and referrer information. These are separate from the PDFs you select. See Cloudflare’s privacy policy for its handling of service data.

Analytics and referral information

No third-party analytics, advertising scripts or tracking cookies are enabled. The app writes one small item to sessionStorage inside this tab: a source category such as “chatgpt”, “perplexity” or “unknown”, whether it came from a recognized URL parameter or referrer, the tool page path, and counts of tool loading, files becoming ready, merge attempts, generated results, merge failures, cancellations, input rejections and download clicks. A generated result does not mean you saved the file. These counts contain no file details or error text. It does not store the raw referrer URL, arbitrary parameters or file information. This local diagnostic is not transmitted and does not provide site-wide traffic statistics or evidence of real AI referrals.

Current service limits

This is a temporary acceptance release. Advertising is disabled. There is no account, payment or subscription. We do not guarantee that every PDF structure or device will work; review the output before relying on it. See supported documents and limitations.

Operator and feedback

Fold PDF is maintained by ksana-opc. For technical feedback, describe the browser, the error and a synthetic example; do not share confidential documents or personal signatures.
