Compress an Image Without Losing Quality

Truly lossless compression keeps every pixel identical and shrinks files modestly. Visually lossless compression discards only what the eye cannot detect and shrinks files dramatically. Both are available here.

Use the before/after slider to judge the result yourself at full size before downloading.

Lossless vs visually lossless

PNG is lossless: expect 5–25% savings on photographs and much more on flat graphics. JPG and WebP at 85% quality are visually lossless for almost all content while saving 60–90%.

Practical recipe

Start high, then step down only if you need to.

  • Smart Compression → High (85%) for photos you care about
  • WebP output for the best quality-per-byte available today
  • PNG output when you need transparency or pixel-exact graphics
  • Compare with the slider before you download
