Tips

Things worth knowing.

Resize before you compress — fewer pixels beats lower quality every time.

JPEG at quality 80 is usually indistinguishable from the original; lower only if you need the bytes.

PNG is for transparency and sharp edges; WebP saves 25-35% over JPEG at equivalent quality.

Strip EXIF metadata before publishing — it leaks location, device, and timestamps.
