How it works

Complete the job in three clear steps

Choose one JPG, PNG, or BMP image from this device.
Adjust the effect settings and create a sepia-toned PNG with the local Jimp runtime.
Compare the result with the original, then download the new PNG copy.

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

Apply Jimp's deterministic sepia color matrix to an image locally and export a full-resolution PNG copy.

Sepia changes every color channel and is a stylistic effect, not restoration or colorization. Keep the original for archival use.

Lucaden adds a focused workflow, conservative memory limits, before-and-after preview, privacy checks, and exact attribution.

Questions

About this tool

Does Lucaden upload the image?

No. Browser Canvas decodes and exports the image in memory, while the pinned Jimp effect modules change its pixels locally.

What should I verify?

Sepia changes every color channel and is a stylistic effect, not restoration or colorization. Keep the original for archival use.

Which open-source project powers this tool?

Jimp 1.6.1 (MIT) performs the deterministic pixel operation; the browser's Canvas API performs PNG export. The upstream project retains its name, copyright, and license.

Open-source foundations
