Frequently asked questions

Which settings can I adjust?

You get four sliders: brightness, contrast, saturation and hue. Brightness and contrast range from 0.2 to 2, saturation from 0 to 2 (0 gives a grayscale look), and hue rotates the colors from -180 to +180 degrees. A live preview shows every change immediately.

What image formats are supported?

Any image your browser can open works, including JPG, PNG and WebP. When you download, PNG files stay as PNG and every other format is saved as a high-quality JPG.

Are my photos uploaded anywhere?

No. The tool runs 100% in your browser using a canvas — your image is processed locally on your device and never uploaded to any server, so your photos stay completely private.

Will adjusting the image lower its quality?

The preview keeps the original resolution and no quality is lost until you export. PNG downloads are lossless; JPG downloads are saved at a high 0.92 quality setting, so the result looks sharp.

Can I adjust more than one image at a time?

This tool works on one image at a time so you can focus the sliders on a single photo. To adjust another image, just load a new file and the controls reset.

Is there a file size limit?

There is no fixed limit — because everything runs locally, the practical ceiling is your device's memory. Very large photos still work but may take a moment to render the preview.
