Convert WebP images to lossy WebP format with controlled quality reduction
Call this tool from your code in three languages.
# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/webp-to-webp-lossy' \
-F 'file=@/path/to/imageFile.ext'
# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/webp-to-webp-lossy' \
-F 'imageFile=/path/to/file.ext' \
-F 'quality=80' \
-F 'effort=4' \
-F 'method=4' \
-F 'alphaQuality=80' \
-F 'smartSubsample=false'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
