What Is Increase Image Quality?
Increase Image Quality improves a photo's sharpness, size or appearance — enlarging it, smoothing blemishes or lifting a dull image — using in-browser processing so nothing is uploaded.
How to Use It — Step by Step
- Open Increase Image Quality and upload your photo.
- Choose the enhancement or retouching setting.
- Compare the before and after at full size.
- Download the improved photo.
Why Use This Tool?
- Improves an old, small or slightly blurry photo without expert editing skills.
- Enlarges an image for printing or display without a desktop upscaling tool.
- Runs on your device — the photo isn't sent anywhere for processing.
- Free to try different settings until the result looks right.
Supported File Formats
Increase Image Quality accepts: AVIF, BMP, GIF, JFIF, JPEG, JPG, PNG, WEBP. Always confirm the accepted formats on the tool page itself if you are working with an unusual file type.
Quality, Resolution and File Size Considerations
Enhancement tools work within the limits of the source photo — they can sharpen, brighten and smooth what's already there, but they cannot invent detail the camera never captured. A very blurry or very low-resolution source will improve only up to a point; the closer the original is to sharp and well-lit, the better an enhancement tool's result will look.
Is It Safe and Private?
Increase Image Quality runs its processing in your browser using your device's own resources. The tool code does not make an upload request for the file you select, so your file is not sent to a server for this task. Keep in mind that no tool can guarantee what happens after you download and share a file elsewhere — that depends on where you send it next.
Best Practices
- Start from the best-quality version of the photo you have access to.
- Compare the result with the original at full zoom, since enhancement effects can look different at thumbnail size.
- Use a lighter setting first, then increase it if the result still looks flat.
- Keep the original photo in case a different level of enhancement is needed later.
Common Problems and Fixes
The enlarged photo looks soft Upscaling stretches existing pixels; a source photo with low original resolution will not become sharp simply by making it bigger.
Skin looks unnaturally smooth Reduce the retouching or smoothing strength — a lighter setting usually looks more natural than the maximum available.
The result doesn't look different from the original Try a stronger setting, or confirm the photo actually needed the specific correction the tool applies (for example, brightness versus sharpness).
