Frequently asked questions
Can I convert PNG to JPEG without losing transparency?
JPEG does not support transparency. Transparent areas will be filled with white. If you need transparency, convert to PNG or WebP instead.
Which format gives the smallest file?
WebP typically produces files 25-35% smaller than JPEG at equivalent quality, and supports transparency like PNG. It's the best choice for web use.
Does converting an image reduce its quality?
Converting from a lossless format (PNG) to a lossy format (JPEG) reduces quality. Converting between lossy formats (JPEG to WebP) at high quality settings preserves visual quality. Converting JPEG to PNG does not recover lost quality — the file just gets bigger.
Should I convert all my images to WebP?
WebP is the best choice for web use — smaller files with good quality. However, some older software and email clients don't support it. Use WebP for websites, JPEG for email and wide compatibility, and PNG for graphics that need transparency.
