Frequently Asked Questions
Is my image data safe and secure?
Yes, absolutely! All image processing happens directly in your browser using JavaScript. Your images are never uploaded to our servers or stored anywhere. The lightening effect is applied locally on your device, ensuring complete privacy and security.
What's the difference between lighten levels?
The lighten level ranges from 0% (no change) to 100% (maximum brightness). Level 0% keeps your original image, while higher levels progressively brighten the image. Most users find that levels between 20-50% work best for fixing dark photos without overexposing them.
Will lightening reduce image quality?
The output image maintains the same resolution and format as your original image. Moderate lightening (up to 50%) typically preserves image quality well. However, excessive lightening can reduce contrast and introduce noise, so it's best to use moderate adjustments.
Can I lighten specific parts of an image?
This tool applies lightening to the entire image uniformly. For selective lightening of specific areas, you would need specialized photo editing software. However, you can always crop your image first to focus on specific areas before applying the lightening effect.
Why do HEIC files take longer to process?
HEIC files (common on iPhones) need to be converted to JPEG format first since web browsers don't natively support HEIC. This conversion process takes a few extra seconds but ensures compatibility and allows you to work with iPhone photos seamlessly.
What's the best way to fix very dark photos?
For very dark photos, start with a moderate lighten level (30-40%) and gradually increase if needed. Be careful not to over-lighten as this can create a washed-out appearance. If the photo is extremely dark, you might need professional photo editing software for best results.
Does this work on mobile devices?
Yes! The lighten tool is fully responsive and works perfectly on smartphones and tablets. The interface automatically adapts to smaller screens, and you can easily upload photos directly from your device's camera or photo library.
