Most bad photos aren't actually bad. They're underexposed, slightly flat, or shot in light that made everything look a bit off. A photo taken inside under fluorescent lighting looks cold and greenish. A photo taken in the late afternoon sun can look blown out and orange. A quick adjustment fixes these problems in a few seconds without any specialist software.
The mistake most people make is reaching for saturation first. Cranking up the colors is the most tempting adjustment because the effect is dramatic and immediate, but it's almost never the right starting point. Oversaturated images look processed and unnatural. Start with brightness and contrast instead. Get the exposure looking right. Then if the colors still feel lifeless, a small saturation boost of 10 to 20 points goes a long way.
Start with brightness to correct the overall exposure. If the image looks dark, bring it up. If it looks washed out and pale, bring it down slightly. Then move to contrast. Increasing contrast makes the dark areas darker and the light areas lighter, which adds depth and makes the image feel more three-dimensional. Most phone photos benefit from a small contrast boost, around 10 to 15 points, because phone cameras tend to flatten the dynamic range to protect highlights.
Once the light looks right, check the temperature. If the image has a cold blue cast (common with shade, overcast days, or LED lighting), pull the temperature slider slightly toward warm. If it looks too orange or golden (common with tungsten indoor lighting), pull it slightly toward cool. These are usually small adjustments. If you find yourself moving the slider more than halfway across, the original photo had a serious white balance problem and correction might not fully save it.
Sharpening works by increasing the contrast along edges in the image. Used carefully, it makes photos look crisper and more detailed. Used aggressively, it creates halos around edges and makes the image look artificially processed, which is usually worse than the soft original. Since sharpen only shows up in the downloaded file rather than the live preview here, it's worth downloading and checking the result before deciding the amount is right.
A light sharpen of 10 to 20 points is useful for photos that look slightly soft from phone compression or minor camera shake. Skip sharpening entirely on portraits shot up close. Skin texture and pores get amplified quickly and the result is usually unflattering. Sharpening works best on architectural photos, product shots, and landscapes where crisp edges and fine detail are actually what you want to emphasize. If you need to blur a background or obscure sensitive information in a screenshot, the blur slider handles that without any quality issues on the rest of the image.
Expecting the preview to show sharpening
Sharpen is applied only on download, not in the live preview. Move the slider, download, and check the result, don't judge it from what's on screen beforehand.
Assuming WebP output is lossless
PNG is genuinely lossless here. WebP uses the browser's default lossy encoding with no quality control, it's not equivalent to a lossless PNG export even though both are commonly thought of as 'lossless-friendly' formats.
Reaching for saturation first
It's the most tempting slider because the effect is dramatic, but it's rarely the right starting point. Fix brightness and contrast first, then add a small saturation boost only if colors still feel flat.
Over-sharpening portraits
Sharpening amplifies skin texture and pores quickly on close-up portraits. It works much better on architecture, product shots and landscapes with crisp edges to emphasize.
Uploading a HEIC file and assuming it will always work
HEIC support depends on your browser's native image handling rather than a dedicated decoder. If a HEIC upload doesn't load, convert it to JPEG or PNG first.
You can adjust brightness, contrast, saturation, hue rotation, colour temperature (warm/cool), sepia tone, grayscale, sharpen, blur and invert, 10 adjustments in total. They're organised into three groups: Light, Color and Detail.
PNG downloads are fully lossless, no quality is lost beyond the adjustments themselves. WebP downloads here use the browser's default lossy encoding rather than a lossless mode, so there is some additional compression on top of the adjustments. JPEG encoding at high quality (90 and above) is visually lossless for most images. Sharpening permanently modifies pixel values via a convolution pass, this is separate from the format encoding step.
Temperature shifts the colour tone of the image between warm (orange/golden, positive values) and cool (blue-shifted, negative values), approximating the effect of different lighting conditions. Positive values add both a hue shift and a touch of warm sepia tone. Negative values apply a cooling hue shift without an equivalent added tint, so warm corrections and cool corrections don't behave perfectly symmetrically.
The sharpen slider applies a sharpening convolution to the image on download. It enhances edges and fine detail by increasing the contrast between neighbouring pixels, applied via direct pixel manipulation using the Canvas API, not a CSS filter. Use it moderately, over-sharpening can create visible halos around edges.
Every other adjustment updates the live preview instantly because it's applied as a CSS filter on the image you're looking at. Sharpen is different, it's a canvas pixel convolution that only runs when you click Download. Move the slider, then download to see the sharpened result, the on-screen preview won't reflect it beforehand.
No. All adjustments are applied in your browser using the HTML5 Canvas API and CSS filters. Your image never leaves your device.
Yes. Each slider has a Reset button that returns that specific adjustment to its default value. There is also a Reset all option, in the header on desktop and in the footer on mobile, that returns every adjustment to its default at once.
If you upload a PNG or WebP file, that same format is selected by default. For any other upload, including JPEG, AVIF or HEIC, JPEG is selected by default. You can change the output format at any time before downloading.
No, the quality slider only appears for JPEG output, ranging from 40 to 100. WebP downloads use the browser's default encoding quality with no adjustable parameter here.
No. The image is drawn onto a canvas and re-encoded on download, so EXIF metadata, including GPS location, does not carry over to the downloaded file.
This page handles one image at a time. For batch processing across multiple files, use the main image editor on the homepage.
HEIC is listed as an accepted format, but this tool relies on your browser's native image support rather than a dedicated HEIC decoder. Support can vary by browser. If your HEIC file doesn't load, convert it to JPEG or PNG first using the HEIC converter, then adjust the converted file here.
