Worked example

Example: compress a 4 MB product PNG to JPEG at 85% for catalog listings when transparency is not needed.

When to use this

  • Quick one-off compression without Photoshop.
  • Mobile uploads before posting to social.
  • Shrinking attachments before email.

Common examples

  • 2.8 MB hero JPG at 80% quality WebP → often under 500 KB for blog headers.
  • 4 MB product PNG → JPEG export at 85% for catalog listings when transparency is not needed.
  • Batch of blog images resized to 1200 px wide then compressed → faster LCP on static sites.
  • 1.8 MB team photo → WebP at Balanced for about 200 KB on careers page.
  • Ecommerce PNG with transparency → compress without converting to JPEG when alpha matters.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs in your browser—files are not uploaded to a server.

Limitations

Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

Privacy and file handling

Your data is processed in your browser and is not uploaded to our server.
