About this tool
Make your image brighter or darker.
Everything happens inside your browser, so the image is never uploaded, and the file you download is exactly what you saw in the preview.
Frequently asked questions
- Do I need an account to brighten image?
- No. There is no signup, no email, and no watermark on the result. Open the page, do the job, and close the tab.
- Which image formats are supported?
- JPG, PNG, WebP, HEIC and TIFF. HEIC photos from an iPhone are decoded in the browser, so they work even where desktop software often fails.
- Are my images uploaded to a server?
- No. Every image is processed by your own browser, so the file never leaves your device and there is nothing for us to store or see.
- Is this tool free?
- Yes, completely free with no signup, no watermark and no limit on how many images you process.
