Use WebP for efficient modern websites, JPG for photographic compatibility, and PNG for crisp lossless graphics or transparency. Conversion preserves the original pixel dimensions.
Frequently Asked Questions
Are my images uploaded? +
No. Reading, conversion, previews, ZIP creation, and downloads happen in your browser.
Which formats support transparency? +
PNG and WebP support transparency. JPG does not, so transparent pixels use your selected background color.
Why can the converted image be larger? +
Lossless PNG or high quality settings can create a larger file than an optimized source. The exact change is shown for every image.
Does conversion resize images? +
No. The original width and height are preserved.
Does quality affect PNG? +
Browser PNG export is lossless, so the quality slider applies to JPG and WebP.
