Now open Google Chrome, type sharpen image online for free, and click search, the results you get are as follows. Please note that each user may get different page results due to different regions, search history, browser cache, and personalized search settings. This article is based on the current search results and filters out the featured snippets in the 0 position.

1. Sharpen Image

Sharpen Image is a totally free tool that helps to sharpen images online. Just drop the image in the tool and set the sharpen percentage to improve the apparent sharpness, then preview the sharpened image and download if expected sharpness is attained. The whole process is easy and quick. But its effect and the website interface filled with ads just can’t make it rank first. Focusing on the processing effect, the sharpening effect can indeed be clearly seen with the adjustment of the sharpening amount. However, since the uploaded photo itself is a bit blurry, the sharpening only adds more graininess.

2. PicWish

PicWish is the most perfect of the three free online sharpeners. After uploading the image, you will enter a very simple page. The image processing speed is fast and the result is effective. Unlike Sharpen Image and Pixelied, PicWish can directly sharpen and repair blurred images and save processed pictures without a watermark. Among the top three pages, this is the most recommended one to try.

3. Pixelied

The effect of Pixelied is similar to that of Sharpen Image, and it is completely free of sharpening, but there is also no enhancement function for those relatively blurred pictures. In its AI Image Tools section, there is an Image Sharpener tool that can sharpen images to fix blurred pictures. However, it is not free and users need to purchase it firstly. Overall, the tool's interface is clear and ad-free, and it can be considered a relatively comprehensive image editor. However, for people who want to sharpen blurred images online for free, this free online sharpener is not enough to meet their needs.

Conclusion of Three Online Free Sharpener

Price: The sharpening features of all three tools are completely free. The AI Image Sharpener tool of Pixelied is charged.

Results: Sharpen Image and Pixelied both only sharpen images singularly and do not enhance them. PicWish can sharpen and fix blurry images

Interface: Apart from Sharpen Image which is full of ads on its homepage, the other two are clean and user-friendly.
