Compress JPG Files Online

JPG is the universal photo format, accepted by every website, portal and email client. This page defaults to JPG output so you get a file that works everywhere.

Quality is chosen by binary search when you set a target size, so you always get the highest quality that fits.

When JPG is the right choice

Use JPG for photographs, scanned documents and any image with smooth gradients. Avoid it for logos, screenshots with crisp text, or anything needing transparency — JPG has no alpha channel and will place a white background behind transparent areas.

Understanding JPG quality numbers

Quality is a perceptual dial, not a percentage of detail retained.

  • 90–95%: near-original, large files, for printing or editing
  • 75–85%: the web standard, no visible artefacts
  • 50–70%: small files, faint softening in fine texture
  • Below 50%: visible blocking around edges
