What should a website image workflow control?

A practical workflow should control dimensions, output format, compression, file names and metadata together. Kompixa applies those settings to a local batch and keeps per-file output measurements visible.

Evidence on this page

The page links to the published browser format benchmark instead of making an unsupported universal format claim.

Important limit

The best production format and quality still depend on the real images, browser support, CDN setup and visual requirements.

Batch processing and predictable file names

How it works

Prepare web-ready images with WebP conversion, sensible dimensions, smaller files and clean names.

Common questions

Are my images uploaded?

No. Processing runs inside your browser and the original files are not sent to Kompixa.

Which formats work?

This first release supports JPEG, PNG and WebP. Browser support can vary.

What is this workflow optimized for?

Prepare web-ready images with WebP conversion, sensible dimensions, smaller files and clean names.

Practical guide

Measured browser evidence

Smaller files came with an encoding-time trade-off

The same 100-scene run reported median sizes of 22.5 KB for WebP 82, 25.4 KB for JPEG 82 and 128.6 KB for PNG. Median browser encode time was 17.0 ms for WebP versus 5.8 ms for JPEG on this device. Delivery size and local processing time are separate decisions.
