Why your profile picture looks blurry
Often the photo was sharp once. Somewhere between the camera and the profile it lost detail. Here is where that happens, and what to do.
It lost detail on the way
- It was sent through a chat. Chat apps make photos smaller and compress them to save data. The copy you received is not the photo that was taken. Ask for the original as a file, or use the one in your own camera roll.
- It is a screenshot. A screenshot holds only the pixels of your screen, often fewer than the photo had. Save the photo itself instead.
- It was saved from a website. Sites shrink and compress photos for speed. The version on a site is rarely the best one.
- It was cropped from a small part. A face cut out of a group photo, then enlarged, has few pixels to show. Take a photo of just you instead.
It was never quite sharp
- The focus was on the background. Tap your face on the screen before you take the photo.
- Something moved. In low light a phone keeps its shutter open longer, and a little movement smears it. Find more light, hold the phone with both hands, or rest it on something.
- The lens was smudged. A fingerprint gives a soft haze over the whole photo, with glowing edges around lights. Wipe it.
- Digital zoom. Zooming past the phone's own lenses only enlarges pixels. Step closer instead, or use the 2× or 3× lens if your phone has one.
How to tell which one it is
The check measures how much real fine detail a photo has: it makes the photo half as big and back again, and sees how much changes. A photo that was enlarged before, or is soft all over, hardly changes. It also notices when a photo is compressed heavily for its size, which is what chats do. It is the same measurement Dewshot itself makes before a retouch. If the background is soft but your face is sharp, it looks at your face alone: a blurred background is fine.
Our rule: a photo under 900 pixels on its long side is too small to look good when someone opens it. A face under 200 pixels wide holds little detail.
Can blur be fixed afterwards?
A little. Sharpening makes edges crisper, and an AI tool can invent plausible detail, but invented detail is not your face. The honest fix is the original file, or a new photo.
Questions
My photo looks sharp on my phone but blurry on my profile. Why?
Your phone shows you the full photo. The profile shows a copy the app made smaller and compressed. Upload a larger original, cropped square, so the app has more to work with.
Is HEIC better than JPEG?
HEIC keeps the same detail in a smaller file. Some apps and browsers cannot open it yet; a JPEG works everywhere. Either is fine as long as it is the original.
