Convert images between JPG, PNG, WebP, GIF, and BMP formats online. Free image converter — batch convert and adjust quality. No watermarks, no signup required.
Image format conversion is a common task in web development and content workflows. Converting PNG screenshots to JPG reduces file size for faster page loads. Converting to WebP provides the best quality-to-size ratio for modern browsers. Converting to SVG-friendly formats like PNG preserves transparency. This tool handles batch conversion so you can process multiple images at once without installing desktop software.
All processing for Image Converter runs entirely in your browser. Your data — whether text, files, or other content — is never transmitted to any server. DevToolHub has no backend that receives or stores your inputs. This means the tool works even offline once the page has loaded, and there is no risk of your data being intercepted or stored by a third party.
Will I lose quality when I convert my image?
It depends on the conversion direction. PNG to JPG introduces lossy compression but a much smaller file. JPG to PNG stops further quality loss. PNG or JPG to WebP generally preserves quality while reducing file size.
Where are my images processed?
All image conversion runs directly in your browser using the HTML5 Canvas API. Your images are never uploaded to any server.
Can I convert multiple images at once?
Yes. Select multiple files in the upload dialog by holding Ctrl or Cmd, and all selected images will be converted to your chosen format.
