Bulk Image Compressor & WebP Converter

How to use Bulk Image Compressor & WebP Converter with a clear next step.

Select the source images, choose a practical quality and maximum edge, then create the local copies. Compare the before-and-after sizes and open a sample output at the actual place it will be used. Download the ZIP only after you are satisfied with the visible quality.

Include a photograph, an image with small lettering and any transparent logo so you can see how the chosen quality and edge setting affect different content. Compare the reported sizes individually; an average saving can hide an image that became larger or lost important detail. Keep filenames distinctive enough to connect each downloaded copy to its source after extracting the ZIP. If the browser slows or stops, reduce the batch and close unnecessary tabs to lower memory demand instead of repeatedly restarting the full selection. Open several extracted images, including the largest and the last item, to check that the archive is complete. A successful ZIP download does not by itself verify image quality. Keep source images in their original folder and publish only copies that suit the intended page, message or upload requirement.

Each selected image is decoded and re-encoded in the browser. A lower file size is not guaranteed for every source image, and compression may change fine detail, transparency handling, or compatibility. The result screen reports the real size change instead of assuming every copy will be smaller.
