Image Enhancer
Adjust brightness, contrast, saturation, tint, sharpness and blur, and boost individual colors, with a live preview
Free Online Image Enhancer - Fix Brightness, Color, Sharpness and More
A photo that looks flat, too dark, or slightly off in color usually does not need a full editing suite, it needs three or four small corrections. The EzyIMG Image Enhancer puts those corrections in one place: brightness, contrast, saturation, vibrance, temperature, tint, hue shift, sharpness and blur, all with a live preview that updates as you drag each slider. Hold the Hold to see original button at any moment to compare your edit against the untouched photo, and use Auto adjust to let the tool analyze the photo and correct it for you, with a strength bar to choose how much of the correction to keep, or pick one of the presets (Vivid, Warm, Cool, Crisp, Soft, Faded, B&W, Pop), each with its own strength bar, as a starting point before fine-tuning.
The feature most online enhancers skip is saturation by color. Instead of pushing saturation for the whole picture, which turns skin tones orange and washes out highlights, you can boost or mute the reds, oranges, yellows, greens, cyans, blues, purples and magentas independently. That makes it easy to deepen a blue sky, make grass look greener, or tone down an overly red face while leaving everything else alone. Everything runs in your browser on the Canvas API, so your photo is never uploaded, there is no watermark, and no account is needed. When you are happy with the result, export it as PNG, JPG or WebP, then use the quick actions below the result to convert the format, resize, crop, rotate or compress the enhanced image in one more click.
How to Use
- 1
Upload your photo
Drop a JPG, PNG, WebP, GIF or BMP image. Very large photos are scaled to 6000 pixels on the longest side so the browser stays responsive.
- 2
Try Auto adjust first
Click Auto adjust to fix exposure, contrast, color cast and dull colors in one step, then use the strength bar to choose anywhere from 0 to 100 percent of the correction.
- 3
Start with a preset or the sliders
Pick a preset for a quick look, or drag Brightness, Contrast, Saturation, Vibrance, Temperature, Tint, Hue, Sharpness and Blur yourself. Click a slider's value to reset it.
- 4
Fine-tune individual colors
Use Saturation by color to push blues, greens, reds and the other color ranges up or down without changing the rest of the image.
- 5
Compare with the original
Press and hold Hold to see original to check how far you have pushed the edit.
- 6
Export and keep going
Choose PNG, JPG or WebP, click Apply and export, download, or send the result straight to Convert, Resize, Crop, Rotate or Optimize with the quick actions.
Key Features
- →Adjust Vibrance before Saturation. Vibrance mostly lifts the muted colors and protects skin tones, so it rarely looks over-processed.
- →For a dull sky, raise the Blue and Cyan saturation and add a little Contrast instead of pushing global Saturation.
- →Use Temperature to fix a yellow indoor cast (move it negative) or a cold, blue shadow look (move it positive). Tint corrects green or magenta casts from fluorescent light.
- →Sharpen last and keep it moderate. Around 30 to 50 is plenty for most photos, and very high values create halos around edges.
- →Export as PNG to keep every detail, or WebP at 85 to 92 percent quality for a much smaller file that still looks the same.
Frequently Asked Questions
Is the Image Enhancer really free?
Yes. There is no account, no watermark and no limit on how many photos you enhance.
Are my photos uploaded anywhere?
No. All adjustments run locally in your browser. The image never leaves your device.
What does Auto adjust do?
It measures the brightness range, average exposure, color balance and color intensity of your photo and suggests corrections for each. The strength bar scales the whole correction, so 50 percent gives a subtler result and 100 percent applies it fully.
Can I use a filter at less than full strength?
Yes. When you pick a preset such as Vivid or Warm, a strength bar appears right below it. Drag it from 0 to 100 percent to apply only part of the filter, for example a subtle warm tone instead of a strong one.
What does saturation by color do?
It changes the intensity of one color range only. For example, raising Blue makes skies and water richer while skin tones, greens and everything else stay exactly as they were.
What is the difference between Saturation and Vibrance?
Saturation scales every color equally. Vibrance boosts the colors that are currently dull more than the ones that are already vivid, so the result looks more natural and skin tones are protected.
Can I enhance HEIC photos from my iPhone?
Convert them to JPG first with the free Image Converter. After the conversion, use the Enhance quick action to bring the converted photo straight into this tool.
