What each control does
- Auto fix looks at how bright every part of the photo is, ignores the darkest and lightest half a percent (usually tiny specks), and stretches the rest across the full range from black to white. Photos taken indoors or on a grey day get their contrast back without you guessing the numbers.
- Brightness lightens or darkens everything by the same amount.
- Contrast pushes dark areas darker and light areas lighter, which makes a flat picture look sharper. Too much loses detail in shadows and sky.
- Saturation makes colours stronger or weaker; all the way down gives black and white.
- Warmth adds a gentle orange tint (sunset, candlelight) or a blue one (crisp winter look). It is useful for correcting photos taken under yellow indoor lights.
Quick looks
Vivid gives food, travel and product photos more punch; Warm and Cool change the mood; Black & white removes the colour and adds a little contrast so it does not look grey. Each look just sets the sliders, so you can adjust it afterwards. Reset goes back to the untouched photo.
Worked example: a photo of a living room taken in the evening is dim, its brightest pixels only reach about 190 out of 255. Auto fix stretches that range to 0–255, so the room looks about a third brighter while the dark corners stay dark. Adding Warmth −15 then removes the yellow cast from the ceiling light, and the photo is ready for a property listing or a family album.
Good to know
- The preview is a smaller copy so the sliders stay quick; the download is made from your original at full size (up to 6000 pixels on the longest side).
- JPEG files are smaller and right for photos. PNG keeps every detail but is several times larger.
- The saved file is new, so location data and camera details stored in the original are not copied.
- No editing can fix a blurred photo – if it was out of focus, take it again.
