Click to applyConversion redraws the image on a canvas, so metadata (EXIF, shooting info) isn't preserved. PNG is lossless so the quality setting doesn't apply, and JPG/BMP have no alpha channel, so transparent areas are automatically filled with white. BMP and ICO are built with a custom encoder, so they work regardless of browser support.

How to use
Click the area above or drag and drop the images you want to convert — you can pick several at once.
Set the output format (PNG/JPG/WEBP/BMP/ICO), and quality or a max size if you need them.
Dropped files convert automatically, and the result list shows the size change versus the original.
Save files individually, or click "Save all" to download everything at once.
