What is Image Converter?
Image Converter re-encodes a picture into PNG, JPEG, or WebP using your browser's built-in canvas, with a live preview and a before/after size comparison. Drop an image, choose a target format, and download the result — no upload, no quality survey, no account. Every pixel is processed on your device and nothing is ever sent to a server.
How to use Image Converter
Drop an image
Drag a file onto the drop zone or click to browse. PNG, JPEG, and WebP are fully supported, and other common image types like GIF or BMP can be read as the source.
Pick a target format
The source format is detected and shown for reference. Choose PNG, JPEG, or WebP from the Target format dropdown; the tool defaults to a format different from your original.
Check the preview and size
The converted image renders instantly, and a summary line shows the old size versus the new one — with the difference highlighted so you can see how much you saved.
Download the result
Click Download as to save the converted image, keeping your original filename with the new extension. Choose New image to convert another file.
