Frequently Asked Questions
Which image format should I use?
Use WebP for the smallest web files, JPG for photographs, and PNG when you need transparency or crisp edges like logos and screenshots.
What happens to transparency when converting to JPG?
JPG doesn't support transparency, so transparent areas are filled with a solid background (usually white) during conversion. Use PNG or WebP to keep transparency.
Is the conversion lossless?
Converting to PNG is lossless; converting to JPG or WebP is lossy and controlled by the quality setting. Higher quality means a larger file.
