常见问题解答

Is there any quality loss when converting between image formats?
Converting to JPG involves lossy compression, which can reduce quality slightly. Converting to PNG is lossless. Converting to WebP uses high-efficiency compression that looks nearly identical to JPG at smaller file sizes.
Why would I convert PNG to JPG?
PNG files are much larger than JPG for photographs. Converting to JPG can reduce file size by 60-90% with minimal visible quality loss. JPG is also more universally compatible with older software.
Why would I convert JPG to PNG?
PNG supports transparency which JPG does not. If you need to remove a background, edit text, or use the image in a design with a transparent layer, PNG is the correct format.
How long does the conversion take?
Instantly — typically under 1 second for images up to 10MB. Because the conversion runs in your browser, there are no upload or download wait times.
