A: JPEG at 80% quality is nearly indistinguishable from the original to most viewers, while significantly reducing file size. Keep text-heavy images as PNG for sharpness. Q: Which is smaller — PNG or JPEG? A: Photos are smaller as JPEG. Logos and graphics with flat colors are smaller as PNG. WebP is generally smaller than both. Q: Are images uploaded to a server? A: No. All processing happens locally in your browser. Your images never leave your device.
