Frequently Asked Questions
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.
