02
Select WebP
Choose WebP as the output, adjust the maximum dimensions and set quality. Smaller dimensions and lower quality can reduce file size at the expense of detail.
03
Review the output
Preview a single converted image and compare the measured file size. Multiple outputs are packaged in a ZIP. Check your destination accepts WebP.
Know what to expect
Browser encoding support is required. Conversion is not intended for archival masters, animation or print colour proofing.
Source files stay in the current browser page and clear on reload. Save the output before leaving, and retain original files for important work.
