Adjust Image Colors

Every slider starts at the setting that leaves the image unchanged, and Reset All puts them all back.

The presets work like photo filters, but each just moves the sliders, so you can fine-tune from there:

• Vivid: Contrast 110%, Saturation 140%. For photos that look dull.
• Warm and Cool: Hue Rotate 15° or -15°, with Saturation 110% or 90%. They shift every colour a little round the colour wheel, so skies drift towards purple (Warm) or cyan (Cool). Whites and greys stay as they are, so they don’t work like a camera’s white balance setting.
• Vintage: Sepia 40%, Contrast 90%, Saturation 80%, for a softer, faded-print look.
• B&W: Grayscale 100%.
• High Contrast: Brightness 105%, Contrast 140%. Useful for photographed documents and hazy photos.
• Faded: Brightness 110%, Contrast 85%, Saturation 70%, for a light, matte look.

Small changes usually look best. A good order:

• Raise Brightness until the subject is clear, often to around 110 to 130%. Stop before the sky or other bright areas turn plain white, because detail lost there can’t be brought back.
• Add a little Contrast if the photo still looks flat or hazy.
• Nudge Saturation up if the colours look dull, keeping an eye on skin tones.

These sliders change the whole image equally. There are no curves or separate shadow and highlight controls, so a photo with a bright sky and a very dark foreground may need a full photo editor. To judge the result, open the original and the adjusted copy side by side in Compare Two Images.

Press B&W. The result is true greyscale, with red, green and blue equal in every pixel; Saturation at 0% gives practically the same result. For a punchier look, add some Contrast as well.

For a brown, old-photo tone, set Sepia to 100% instead of pressing B&W. Grayscale is applied after Sepia, so using both removes the brown again.

Add as many images as you like, with Add more images for extras, and every one gets exactly the same settings when you apply them. That keeps a set of product photos or a gallery consistent. They download together as adjusted_images.zip, and if two files share a name, the second becomes photo_adjusted-1.jpg instead of replacing the first.

If you change a setting after applying, the Download button disappears until you apply again, so the download always matches the preview. Photos taken in very different light may need their own settings, so adjust similar ones together.

• The same format and size: a JPG comes back as a JPG (saved at 92% quality), a PNG as a PNG and a WebP as a WebP, with the same width and height.
• Transparency kept: transparent areas of PNG and WebP images stay transparent.
• Other formats: iPhone HEIC photos come back as JPG. AVIF, GIF and SVG files come back as PNG.
• Upright photos: phone photos stored sideways with a rotation tag come out the right way up.
• No camera data: the adjusted copy doesn’t include the original’s EXIF data, such as the camera model and GPS location. Your original file isn’t changed.

Every adjustment is made by your browser, on your own device, so your photos are never uploaded. That matters for family photos and clients’ work.
