What this tool does

Image Brightness decodes a local image with browser APIs, adjusts visible pixel brightness on canvas, and creates a downloadable output without uploading the source file.

Common use cases

Brighten or darken a browser-local image for quick visual cleanup, documentation screenshots, thumbnails, and draft assets before exporting.

Use Image Brightness when you need to prepare an image for a website, upload form, document, support ticket, or shareable asset while keeping the file in your browser and moving only to related image conversion or optimization tools when needed.

Move the brightness slider toward positive values to brighten or negative values to darken.
Apply the adjustment, then download the processed image from your browser.

Example workflow
