Questions
Will Utilumo build one converter per format?
No. One Image Converter accepts common formats and lets format-specific SEO pages reuse the same engine.
Which output formats are supported?
It exports JPG, PNG, WebP, and AVIF when the browser supports the selected format.
Can this convert transparent images to JPG?
Yes. Transparent pixels are drawn onto a white background when exporting JPG because JPG does not support transparency.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
