About this tool
Give a flat image more punch, with a live preview.
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 increase contrast?
- 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.
