About this tool
Re-encodes PNG images as JPG through the browser's Canvas API, compositing any transparent regions onto a white background before JPEG compression. Photographs saved as PNG typically shrink by 50--90% after conversion because JPG's lossy DCT compression is far more efficient for continuous-tone imagery than PNG's lossless deflate. The quality slider lets you balance sharpness against file size — 85% is a good starting point for screenshots destined for Slack or email.
