About this tool

Compress Image to Target KB

Target KB means 1 KB equals 1,024 bytes. Bounded attempts adjust quality and, when needed, dimensions; an unreachable target returns an explicit failure instead of a size guarantee.

  • Binary KB is defined
  • Tolerance is explained
  • No exact-size or quality guarantee

Good to know

Helpful notes

Use Target KB when a form or upload has a file-size limit. Choose a preset or enter a KB target; FileFit makes bounded attempts to fit beneath it.

The result depends on image detail, format, quality and whether resizing is allowed. A target is not a guarantee; FileFit reports when it cannot reach the requested size with your settings.

Before you begin

Compress Image to Target KB questions

Does Target KB guarantee an exact size?

No. FileFit reports whether the target was reached instead of presenting an over-target result as success.

Can dimensions change?

The recommended setting may reduce dimensions only when needed. You can choose to keep the original dimensions.

How is this different from Compress Image?

Target KB starts with a requested maximum size and reports whether it was reached. Compress Image is better for general size reduction when you do not have a required limit.

Is my image uploaded?

Supported images are processed locally first. Any available temporary server path requires clear confirmation before upload.
