Bring back crisp detail
Sharpening makes edges more defined: eyelashes, text, leaves and the texture of fabric look crisper. It cannot fix a photo that is badly out of focus or blurred by movement, but it does help pictures that are just a little soft, for example after resizing, after a phone's noise reduction or when a photo was taken through glass.
This page opens the editor with the Sharpen slider selected. The Clarity slider in the same panel is useful too, because it strengthens larger textures rather than the finest edges.
How to sharpen a photo
Load the photo
Start with the sharpest copy you have, not a screenshot of it.
Zoom in
Look at an area with fine detail, such as eyes or text, at 100% zoom. Sharpening is hard to judge on a small preview.
Raise Sharpen gradually
Stop as soon as the detail looks crisp. If bright outlines appear along edges, go back a little.
Export
Save the result. If you also pick an Instagram size, the sharpening scales with the photo, so the download looks like the preview.
Sharpen, clarity or contrast?
Sharpen
Fine edges, a few pixels wide. Best for eyes, hair, text, product details.
Clarity
Medium-sized textures. Best for clouds, rocks, buildings and anything that should look gritty.
Contrast
The whole image from dark to light. Makes a picture punchier but not more detailed; see the contrast tool.
Signs of over-sharpening
- Halos. Light outlines around dark objects, especially against the sky.
- Crunchy skin. Pores and small wrinkles become loud. For portraits, keep Sharpen low and do not add Clarity.
- Stronger noise. Sharpening also sharpens grain. On a noisy night shot, sharpen less.
- Jagged lines. Thin diagonal lines start to look like steps.
Instagram compresses and may resize uploads, which softens them slightly. A small amount of sharpening on a picture that is already 1080 pixels wide survives that step best; the Instagram image resizer gets your photo to that size first.
Sharpening questions
Can sharpening fix a blurry photo?
Only slightly soft photos improve noticeably. Strong motion blur or a missed focus cannot be undone by sharpening; the detail was never recorded.
Should I sharpen before or after resizing?
In most programs, after: resizing down softens edges a bit, so sharpening at the final size gives the most control. In this editor you do not have to plan the order, because sharpening is scaled to the size you export.
Why does my photo look sharp on my phone but soft on Instagram?
Instagram scales photos wider than 1080 pixels down and recompresses them. Resize to 1080 pixels wide yourself and add a small amount of sharpening before uploading.
Can I sharpen just the face?
The Sharpen slider works on the whole photo. Keep it moderate so the background and skin stay smooth.
The opposite effect
For a softer picture, use the blur tool. Sharpening and the other finishing steps are grouped under photo editor tools.
