Online image enhancer for colour, detail and sharpness
This browser-based image enhancer online improves photographs without requiring desktop software. It can correct a colour cast, balance contrast, increase vibrance, reduce light image noise, smooth skin-toned regions carefully and sharpen visible edges. Choose Natural for restrained photo enhancement or Strong when a flat, soft or low-contrast picture needs a more noticeable correction.
The tool also works as a practical photo upscaler. Select 2× to double the width and height or 4× to create a larger output for printing, documents, profile images, product listings and presentations. Enlargement cannot recreate detail that was never captured, but high-quality resampling followed by controlled detail recovery usually looks cleaner than a basic browser resize.
Use the side-by-side view to compare the original with the enhanced image before export. PNG is useful when the source contains transparency or when lossless output is preferred. JPG normally creates a smaller photographic file. After enhancement, you can reduce delivery size with Compress Image, create a cutout with the Image Background Remover, or apply layout text with Add Text to Photo.
What this photo enhancer improves
Each preset combines several image-processing stages rather than applying one generic filter.
Colour balance
Reduces common colour casts and adds restrained vibrance without simply oversaturating every pixel.
Contrast and tone
Uses sampled tonal information to improve flat images while limiting excessive highlight and shadow clipping.
Sharpening and clarity
Applies controlled local contrast and unsharp masking to improve soft edges and medium-scale detail.
Skin-aware smoothing
Targets likely skin-tone regions so portraits can be softened without blurring the complete photograph.
1×, 2× and 4× output
Keep the original dimensions or create a larger image using high-quality browser resampling.
Local processing
The selected image and generated result are processed in browser memory and are not uploaded to CorrectionCopy.
Privacy, compatibility and practical limits
Private browser workflow
Your image is decoded, enhanced and exported locally. Resetting the tool releases the active preview, worker and temporary object URLs.
Device-aware output
Large 4× results require substantial memory. The tool measures the requested workload and scales to a safer output only when the browser is unlikely to complete the full dimensions.
Supported files
JPG, PNG and WebP work in current browsers. GIF, BMP, AVIF, HEIC or HEIF depend on the browser’s built-in decoder and may need conversion first.
Enhancement limitations
Mild blur, noise and flat colour can improve visibly. Severe motion blur, extreme compression damage or missing facial detail cannot be reconstructed reliably by this non-generative enhancer.
Troubleshooting the image enhancer
Why did my 4× output become smaller than the exact requested dimensions?
The requested output exceeded the device-aware working capacity estimated for your browser. The tool reduced the final dimensions proportionally to avoid a blank canvas, crash or corrupt download.
Why can the browser open my image but not export it?
Very large decoded images can exceed the browser’s canvas memory even when the original file size is modest. Try 2× instead of 4×, close other memory-heavy tabs, or use a desktop browser.
Why does HEIC or HEIF fail on some devices?
HEIC decoding is controlled by the browser and operating system. Convert the image to JPG first when the current browser cannot decode it.
Why is the strong preset too intense for one photo?
Strong enhancement deliberately increases contrast, clarity and sharpening. Switch to Natural for portraits, already-edited photos or images with delicate highlights.
Image Enhancer frequently asked questions
How do I enhance image quality online?
Add a JPG, PNG or WebP image, choose Natural or Strong enhancement, select the output scale, compare the result and download JPG or PNG.
Can this tool sharpen a blurry photo?
It can improve mild softness using clarity and unsharp masking. Severe camera shake, subject movement or heavily out-of-focus detail cannot be fully recovered.
Does 4× upscaling create real new detail?
This enhancer uses high-quality resampling and detail recovery rather than generative reconstruction. It creates a larger, cleaner-looking image but does not invent reliable details that were absent from the source.
What is the difference between Natural and Strong?
Natural applies balanced colour, tone, denoise, skin and sharpening adjustments. Strong increases those corrections for flat, dull or visibly soft photographs.
Can I keep PNG transparency?
Yes. Download PNG when the original contains transparency. JPG does not support transparency and is intended for normal photographic backgrounds.
Are my photos uploaded or stored?
No. Image decoding, enhancement and export occur in the browser. CorrectionCopy does not receive or store the selected photo.
Does the image enhancer work on phones?
Yes, on modern mobile browsers. Large source images and 4× output can be memory-intensive, so 1× or 2× may be more suitable on lower-memory phones.
Can I enhance the same image more than once?
Yes. Change the preset or scale, use Undo and Redo for settings, download more than one format, or replace the source image without reloading the page.
