What Online Image Exposure Adjustment Tool does
Simulate increasing or decreasing image exposure
Worked example
Input
One supported image plus an exposure amount or threshold
Result
A processed preview and downloadable image
How the pixels are processed
Exposure scales light intensity; solarization conditionally inverts channels above the selected threshold.
Useful workflows
- Prepare web graphics, product images, presentations or visual test fixtures.
- Compare the preview at 100% zoom before exporting the result.
- Keep consistent settings across related images.
Quality, privacy and compatibility checks
- Repeated lossy export can reduce quality; retain an original and choose an appropriate output format.
- Very large dimensions or batches can exceed browser memory even when total file size appears small.
- Metadata, color profiles, animation and transparency may not be preserved by every canvas export format.
Frequently asked questions
Is the source image uploaded?
The normal editor decodes and processes supported images in this browser without uploading them to an application server.
Why can the downloaded image look different?
Check output format, compression, color profile, transparency, dimensions and whether the browser applied orientation metadata.
