Why process PDFs Client-Side?

Most PDF websites upload your files to a cloud server to process them. This creates a privacy risk for sensitive documents. Selqio is different.

For Data Analysts

Need to merge sensitive BI reports or extract tables from confidential datasets? Our tools run locally, ensuring strict data compliance (GDPR/CCPA) since the data never leaves your firewall.

For Legal & HR

Redact sensitive info or sign contracts without third-party exposure. Your employee records and legal agreements stay on your computer, eliminating the risk of cloud data breaches.

Maximum Performance

Working with 500MB+ blueprints or manuscripts? Skip the upload/download wait time. Browser-based WebAssembly processing is often faster than server-side alternatives for large files.

Frequently Asked Questions

Are my files uploaded to your server?

No. Selqio uses client-side technology. All code runs within your browser. Your PDF files never travel over the internet to us.

Is this PDF toolkit free to use?

Yes, all tools on this page are completely free. There are no hidden paywalls, watermarks, or registration requirements.

Can I use these tools on mobile?

Yes, Selqio is optimized for mobile devices. You can merge, split, and compress PDFs directly on your iPhone or Android device.

What is the file size limit?

Since we don't host your files, there is no artificial upload limit. The limit depends only on your device's available processing power (RAM).
