About PDFflash

PDFflash offers free PDF and file utilities that run in your web browser. Our goal is simple: useful tools with a strong privacy posture—your documents are processed locally on your device whenever the tool allows it.

Who we are

PDFflash is an independent website focused on client-side conversion and PDF utilities. We are not affiliated with Adobe. Product names (such as PDF) belong to their respective owners.

How our tools work

Most tools on this site use JavaScript libraries (for example PDF.js, pdf-lib, or similar) loaded from public CDNs. Processing happens in your browser unless we clearly state otherwise on a specific page. We do not operate a “upload your file to our server” pipeline for those tools.

Because work happens locally, performance and limits depend on your device, browser, and file size. Very large files may fail or be slow.

Advertising

We may display advertisements through Google AdSense or similar programmes. Advertisers may use cookies or similar technologies as described in our Privacy Policy. You can control ad personalisation through your Google account and industry opt-out tools linked from that policy.

Accuracy and acceptable use

Tools are provided “as is” for general use. You are responsible for complying with copyright and applicable laws when processing files. Do not use the site to harm others, distribute malware, or violate terms of service of third-party services.
