Overview

Compress Image creates a quality-controlled image download through the browser-local image worker path. This preview uses the same header checks, pixel guards, and local encoding path as the image converters.

Use Cases

  • Create a smaller copy of a photo before attaching it to forms or messages.
  • Control JPEG quality without uploading the image to a remote compression service.
  • Run a browser-local compression workflow for PNG, JPG, JPEG, or WebP still images.

Limitations

  • This preview outputs a JPEG file by default.
  • Transparency is flattened when the output format is JPG.
  • Input bytes, dimensions, and total pixels are capped before decoding.

FAQ

Does this image compressor upload my file?

No. The selected image is read by the browser and encoded locally for this preview tool.

Can I control quality?

Yes. The preview exposes a quality setting before local browser encoding starts.
