How to edit a photo online
- Drop a photo on the box above or tap to choose one.
- Start with a preset such as Vivid, B&W or Vintage, or go straight to the sliders.
- Adjust brightness, contrast, saturation, warmth and hue. Add black and white, sepia, a vignette, blur or sharpening as needed.
- Press and hold Hold to compare to see the original.
- Choose a format and click Download. The full-resolution photo is processed with the same settings.
What each adjustment does
- Brightness scales every pixel lighter or darker. Contrast pushes tones away from or towards mid-grey.
- Saturation makes colors stronger or more muted; at −100 the photo is grey. Warmth shifts towards orange or blue, like a white balance correction.
- Hue rotates all colors around the color wheel, which is mostly useful for creative effects.
- Vignette darkens the corners to draw the eye to the centre. Sharpen uses an unsharp mask to make edges crisper; a little goes a long way.
The preview is computed on a smaller copy so the sliders stay smooth on phones. Blur strength is scaled so the preview matches the final file.
Private photo editing
All editing happens in your browser with the Canvas API. Your photo is never uploaded, there is no watermark and no sign-up. The saved file contains no EXIF metadata.
Does editing reduce the resolution?
No. Only the preview is scaled down. The download has the same pixel size as your original.
How do I make a photo black and white?
Click the B&W preset or move the Black & white slider to 100. Add some contrast for a punchier look.
Can I undo changes?
Yes. Move any slider back to 0, pick the Original preset or click Reset. Your original file is never modified.
Why does my photo look different in another app?
Saved files use the sRGB color space. Wide-gamut photos from recent phones may look slightly less saturated in apps that show the original P3 colors.
