Brightness or contrast?
Brightness moves every shade lighter or darker. Contrast moves dark and light shades apart, so a flat, greyish photo looks crisper. A dark indoor photo often needs a little of both.
Scans of documents and signatures
A phone photo of white paper often comes out grey. Raise brightness and contrast together until the paper is white and the ink stays dark. For exam signatures, the resizer's "Clean up paper background" option does this automatically.
FAQ
- Can I brighten my passport photo?
- Authorities reject photos changed with software, and the US State Department says it checks for this. Retake a dark passport photo facing a window in daylight instead.
- Why do bright areas turn pure white?
- Pixels that are already near white can't get any brighter, so detail there is lost. Use a smaller brightness change, or add contrast instead.
- Is my photo uploaded?
- No. The editing happens in your browser, so the photo never leaves your device and nothing is stored.
- Which files can I use?
- JPG, PNG, WebP and any other image your browser can open. You get a JPG back, or a PNG if you started with a PNG, so transparency is kept.
