Image Tools FAQ

Should I crop or resize first?

Crop first if the visible area should change. Resize after cropping so the final dimensions match the image you actually want to keep.

Does image compression reduce quality?

Usually yes. JPEG and WebP compression trade some quality for smaller files. PNG compression in the browser may not always make files smaller.

Are my images uploaded?

For tools marked as local processing, image work is designed to happen in your browser. If a future feature requires upload, the page should clearly say so before you use it.

What image format should I use?

Use JPEG for photos, PNG for transparency or sharp graphics, and WebP when you want modern web compression and compatibility is acceptable.

Can I compress an image to a target file size?

Compress Image includes target-size helpers, but browser compression is best-effort and cannot guarantee every image will reach a specific size.
