Frequently Asked Questions

What happens to transparency when converting PNG to JPG?

When converting transparent PNGs to WebP, alpha transparency is preserved losslessly; when converting to JPG, DocScalar directly blends transparency onto a clean background without fringing or dark borders.

Are converted images logged or retained on DocScalar servers?

Never. Image conversion takes place in ephemeral memory buffers over TLS 1.3, and all input and output files are shredded immediately upon download without server persistence.

What is the maximum file size limit for image format conversion?

DocScalar supports files up to 10 MB in instant guest mode with zero registration required, 15 MB for registered free accounts, and up to 1 GB for Pro tier users. All processing executes in isolated memory buffers with zero data retention.

Why should I convert to WebP?

WebP delivers 25% to 35% smaller file sizes than comparable JPG and PNG files at identical visual quality, dramatically speeding up web page loading times and improving core web vitals.
