Image Converter
Convert JPG, PNG, WebP, and AVIF images with one local browser tool.
Drop images to convert
Convert JPG, PNG, WebP, or AVIF images locally. Choose one output format and download each file or the full batch as a ZIP.
Browser-only conversion
Images are decoded, converted, previewed, and exported in this tab. Utilumo does not upload your files.
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. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
