FAQs
Are my images uploaded to a server?
No. Enhancement runs entirely in your browser, so your images are never uploaded or stored anywhere.
What does each slider do?
Brightness lightens or darkens the photo, Contrast boosts the difference between tones, and Saturation controls color intensity.
Why is the download a JPG?
JPG is a universal format that opens everywhere. Transparent areas are filled with white so the photo exports cleanly.
Is the tool free to use?
Yes. Every Handio tool is free, with no sign-up, no limits and no watermarks.

Why use Image Enhancer?
Give flat or underexposed photos a quick lift — adjusting brightness, contrast and saturation against a live preview is enough to save a shot without opening a heavyweight editor.
- Brighten an underexposed phone photo taken indoors before posting it.
- Boost contrast on a scanned document so the text reads clearly.
- Bring out the colors of a product shot before uploading it to a shop.
Tips and Limits
Heavy saturation can clip colors to flat blocks, and pushing brightness too far washes out highlights, so use the sliders in small steps and judge by the preview. The download is always JPG, so transparent areas are filled with white and no transparency is preserved.
