How it works

  1. Add one or more images.
  2. Choose 100 KB, 200 KB, 500 KB, 1 MB or enter another target.
  3. Cifrivo adjusts quality and, if needed, dimensions.
  4. Review warnings and download each image or the batch.

Practical example

For a 200 KB limit, the engine first searches for the best quality at full size and reduces dimensions only when needed.

Formula and explanation

JPG and WebP support a multi-pass quality search; PNG may require a lower resolution.

The tool warns when a target requires extreme degradation or cannot reasonably be reached.

Frequently asked questions

Will output be exactly the requested size?

The target is an approximate maximum. Browser encoding cannot produce every exact byte count.

Why might dimensions change?

They are reduced only when quality adjustments are insufficient, particularly for PNG.

Can I process several images?

Yes. The same target applies to the batch and results can be downloaded as a ZIP.
