Quick FAQ

Frequently Asked Questions (FAQ)

Answers to common questions regarding features, client-side security, and usage.

Q1.Why should I convert images to WebP or AVIF formats?

WebP and AVIF are next-generation image formats recommended by Google. They provide superior compression (26% to 80% smaller than PNG/JPG) while retaining pristine visual fidelity, drastically accelerating page loading times and improving Google Core Web Vitals (LCP) scores.

Q2.Are my photos uploaded to any external server during compression?

No. The entire conversion and compression pipeline uses HTML5 Canvas and native browser APIs directly inside your device memory. Your photos never leave your computer or phone.

Q3.Can I download all converted images at once in a single ZIP file?

Yes! DocWello features instant batch ZIP compression with JSZip, allowing you to download dozens of converted photos in one click.
