Local image bytes · honest target

Reduce bytes, not dimensions

ImageCompress re-encodes one static image as JPEG or WebP and reports whether a bounded quality search actually met your byte budget.

No account · no upload · unchanged pixels · actual Blob bytes

Three explicit steps

From source to measured result

01

Choose one static image

The browser verifies type, animation and decoded resource bounds locally.

02

Choose quality or target

Target mode tests qualities without silently shrinking pixel dimensions.

03

Inspect and download

Preview the exact Blob and read its actual bytes, quality, attempts and status.

Focused compression workflow

What ImageCompress makes explicit

  • Try a byte budget without sending a private image to a processor.
  • Compare JPEG and WebP browser output at unchanged dimensions.
  • See an honest not-met result instead of hidden resizing or a false guarantee.

Reproducible examples

Compression decisions you can repeat

Keep pixel dimensions, choose JPEG or WebP and measure the exact output Blob before downloading.
