What does Auto Enhance do?
Auto Enhance is a free online tool that can adjust image levels, gamma and tonal range. The PNG result from Auto Enhance is a separate copy to inspect before you use it elsewhere. One possible use is flat-looking photos tested for a livelier preview.
Automatic enhancement applies auto-level, auto-gamma and cleanup to an image. It adjusts tonal range without offering separate manual controls for each stage.
This can help a dull-looking photo or scan, but it can also alter the mood and relative brightness of a carefully edited picture. Use the original as your reference and review important colors and highlights before accepting the result.
The output is planned as a convenient trial edit, not a calibrated color correction. Automatic levels and gamma react to the whole picture.
They do not know which part matters most to you. A small bright subject can shift along with a dark background.
Compare the source and result side by side. Keep the original if the change creates an unwanted color or tonal style.
Adjust image tones automatically online: steps
Before using Auto Enhance, decide what the new copy must contain and where it will be used. Choose a picture whose tones you want to test and keep the source as a reference. Review the upload area and all values required by the current Auto Enhance form.

Formats and limits for Auto Enhance
The Auto Enhance form accepts the image formats in the table sources. Each Auto Enhance upload can be up to 300 MB, which equals 300 MiB. The allowed suffixes on the Auto Enhance page do not prove that a source has valid content inside it.

Automatic cleanup can change planned low-contrast or dark scenes. It is unsuitable as a promise of accurate product color reproduction.
How this tool works
Auto Enhance uses ImageMagick to handle the source on the server. The Auto Enhance request uses your chosen input rather than any local editing project left on your device. Check the PNG contents produced by Auto Enhance before treating them as ready for another app or reader.
For Auto Enhance, your browser uploads the source to our file-processing server. This is a server task, not local editing.
Files are due for deletion within 1 hour. Cleanup runs during normal service operation. Keep a local download for future use.
