What does Image Format Converter do?

When a project needs one consistent image format, converting files individually wastes time. This batch converter turns mixed PNG, JPEG, and WebP files into a single web-ready format in one pass.

Conversion is done locally in the browser, so source files stay on your device and download together when finished.

Convert many images to one target format at once.
Move older formats to efficient modern web formats like WebP.
Process files locally without uploading them to a server.

Common use cases

Standardizing a mixed image folder
Converting assets to WebP for performance
Preparing consistent formats for a CMS
