How it works

Complete the job in three clear steps

  1. Add one JPG, PNG, or WebP image to the local workspace.
  2. Choose the visual or compression settings and create a compressed image copy.
  3. Review the local result, then download it before leaving the page.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Practical details

What this Lucaden tool does

Compress a JPG, PNG, or WebP locally with quality, maximum-dimension, and output-format controls plus an immediate before-and-after report.

Compression is lossy and browser encoders can vary. Inspect fine detail, transparency, color, dimensions, and file size before replacing an original.

Lucaden supplies the focused workflow, local-only guardrails, resource limits, and upstream attribution.

  • Metadata removed by default
  • Before-and-after file-size report

Useful for

  • Shrink a website image
  • Reduce an attachment

Questions

About this tool

Does Lucaden upload my content?

No. The pinned open-source runtime processes the temporary content in this browser and this workspace has no upload step.

What should I verify?

Compression is lossy and browser encoders can vary. Inspect fine detail, transparency, color, dimensions, and file size before replacing an original.

Which open-source project powers this tool?

Compressor.js (MIT runtime 1.3.0) powers the local processing. The upstream project retains its original name, copyright, and license.
