Question 1

Is it really private?

Accepted Answer

Yes. Your files never leave your device. All compression and conversion tasks run directly in your web browser via client-side WebAssembly and HTML5 Canvas. Nothing is uploaded to any remote server.

Question 2

What are the file size limits?

Accepted Answer

Because operations run locally in browser memory rather than over a network upload, typical images and documents up to 500MB process smoothly without upload bottlenecks or timeouts.

Question 3

Which file formats are supported?

Accepted Answer

Supported image formats include JPG, JPEG, PNG, WebP, and AVIF. Supported document operations include PDF signing, compression, merging, organizing, page removal, Word to PDF, Word to JPG, PDF to Word, and biometric passport photo creation.

Question 4

Are my files uploaded to any server?

Accepted Answer

Never. Nothing is uploaded. All computation happens entirely within your local web browser session.
