Frequently Asked Questions
Which format should I use?
WebP offers the best compression (25-34% smaller than JPEG at same quality) and is supported by all modern browsers. JPEG is best for photos with smooth gradients. PNG is for images requiring transparency. For the web, always prefer WebP.
What quality setting should I use?
For web images: 75-85% for photos (sweet spot: visually lossless + small file). For thumbnails: 60-70%. For print: 90-100%. WebP can often use quality 70 and look better than JPEG at quality 85.
Is my image uploaded to a server?
No — all compression happens entirely in your browser using the Canvas API. Your images never leave your device. This also means very large images may take a moment to process on slower devices.
