Guide
Auto Enhance rescues photos that look flat, tinted or underexposed by pushing them back to a normal tonal range. It analyses the histogram first and works out four sets of values — automatic levels (opening up the black and white points), grey-world white balance (cancelling an overall colour cast), smart shadow fill, and natural saturation plus clarity — then scales them by the strength you pick and applies them. When a picture already sits in a good range the values come out very small and the tool says “The tone of this image is already close to ideal”. Several images can be run in one batch and the output keeps the original format. Processing happens locally in the browser.

It is built for general photography — landscapes, documents, rephotographed pages, screenshots — and does no face detection; for skin smoothing and face slimming use “Auto Beauty”. The difference from “Photo Restoration” is that this only corrects colour and tone, leaving sharpness and resolution alone.
<original-name>_enhanced.ext. An image over roughly 24 megapixels is scaled down first and the note column says so; click a result's preview to open the before/after popup again.| Input | Output | Notes |
|---|---|---|
A flat, grey landscape shot on an overcast day, Standard |
Black and white points stretch apart and the blue comes back into the sky; no note |
The typical win |
A document rephotographed indoors under an incandescent lamp |
The paper turns white and the text gains contrast |
Grey-world white balance cancels the cast |
A photo that was already correctly exposed |
Barely any change, with the note “Tone already close to ideal, only a slight adjustment” |
It will not over-process |
Dozens of landscapes shot under cloud come back to normal contrast and colour in one run.
Yellowish, dim page photos turn white and legible, ready for OCR.
Bring flat scans through automatic levels first, then decide whether upscaling is worthwhile.
Different shooting sessions give inconsistent white balance; lift them all to the same baseline.
White balance is measured over the whole frame, so when skin fills a lot of it, it can be read as a colour cast. For portraits, try the “Natural” strength or tune the photo by hand in “Image Adjust”.
That one is a repair combination of denoising + levels + sharpening; this one concentrates on tone (levels, white balance, shadow fill, saturation) and runs in batches.
No — the values are derived per image and there are no presets to store.
Histogram analysis and the adjustment both run locally in the browser; photos are not uploaded to any server and are released as soon as the page is closed.

Auto levels, white balance and smart fill light to fix flat, tinted or underexposed landscape and document photos in bulk (not a face beautifier)
This tool does general tonal auto-correction for photos (landscapes, documents, re-photographed pages and screenshots alike) and does no face detection; for portrait smoothing use "One-click beauty". Output keeps the original format, and images over about 24 megapixels are scaled down proportionally first to control memory.
