Frequently Asked Questions
Can I convert multiple images at once?
The current version converts one image at a time. For batch compression, use the Image Compressor.
Does PNG-to-JPEG conversion lose transparency?
Yes. JPEG does not support transparency. Transparent areas are filled with white (or black, depending on the browser) when converting to JPEG.
Why use WebP?
WebP typically achieves 25-35% smaller file sizes than JPEG at equivalent quality, with support for both lossy and lossless compression.
