Why are my screenshots blurry?

This is part of the answers hub. A blurry capture is rarely the capture tool's fault. It is resolution being lost somewhere between the screen and the saved file, and there are four places that happens.

1. Browser zoom below 100%

If the page is zoomed out, the browser renders fewer pixels and the capture inherits that lower detail. Text that looked fine on screen captures soft.

Fix: press Ctrl/Cmd + 0 to reset zoom to 100%, then capture. For dense UI you can zoom in before capturing to get more pixels per element.

2. A small crop scaled up

Cropping keeps only the pixels inside the rectangle. If you then view or embed that crop at a larger size, each source pixel gets stretched. That is the pixelated look. Cropping from a shrunk preview rather than the full-resolution frame makes it worse, because the preview already threw pixels away.

Fix: capture at full resolution and crop from the original frame. A good capture tool keeps the full-res image and applies your crop to that, not to the on-screen preview.

3. The wrong file format, or a re-save

Saving a screenshot as JPEG introduces compression artifacts (faint blocky halos around text and sharp edges) because JPEG is tuned for photographs, not UI. PNG is lossless and keeps text crisp. The same thing happens invisibly when a chat or messaging app recompresses the image on the way to someone else, which is why a screenshot often looks worse to the person receiving it than it did to you.

Fix: save screenshots as PNG, and send the original file rather than a pasted or forwarded copy. The full tradeoff is in the image-format reference.

4. On Windows, the app was blurry before you captured it

This one is not a capture problem at all, and it is the cause most guides miss. Windows renders applications that are not DPI aware at a fixed 96 DPI, then stretches the result to fill a display running above 100% scaling. Microsoft's own developer documentation is blunt about the result: "Windows will stretch the application bitmap to the expected physical size. This results in the application appearing blurry." The same happens to apps that handle only one scale factor when you drag them to a second monitor with a different one.

Your screenshot then records that stretched image accurately. The picture is soft because the window was soft.

Fix: look at the app on screen before you blame the capture. If the window itself is fuzzy, set that display to 100% scaling, keep the app on the monitor it was launched on, or use a version of the app that handles per-monitor scaling.

Does screenshotting reduce quality?

No. A screenshot copies the pixels already on screen, so nothing is compressed or resampled at the moment of capture. What confuses people is screenshotting a photo: the capture records the photo at the size it is being displayed, which is often much smaller than the original image file. Nothing was degraded, you simply captured a smaller version. Open the original at full size before capturing if you need the detail.

A sharp capture your agent can still read

Sharpness matters for humans. But if you are handing the image to a coding agent, legibility and format both matter. A crisp PNG that the agent cannot ingest is still a dead end. See why your agent can't read your screenshot.

Frequently asked questions

Why are my screenshots blurry?

Something scaled the pixels. The four usual causes are browser zoom below 100%, a small crop displayed at a larger size, saving or re-saving as JPEG, and, on Windows, capturing an app that Windows itself is stretching because the app is not DPI aware. The capture step adds no blur of its own.

Why do screenshots come out blurry?

The capture is pixel exact, so a soft result means the pixels were already scaled somewhere. Reset browser zoom to 100% with Ctrl/Cmd+0, capture at full resolution rather than cropping from a shrunk preview, and keep the PNG original instead of a JPEG copy. On Windows, also check whether the app looked soft on screen before you captured it.

Does screenshotting reduce quality?

No. A screenshot copies the exact pixels being displayed, with no compression of its own. Screenshotting a photo captures it at the size it is shown, which can be smaller than the original file, but the capture itself adds no loss.

Do screenshots lose quality?

Not when they are taken. They lose quality afterwards: saving as JPEG, scaling the image up or down, or a messaging app recompressing it on the way to someone else. Keep the PNG original and share that file.

How do I fix blurry screenshots?

Reset zoom to 100% and recapture, capture at full resolution and crop from the original frame rather than a preview, save as PNG rather than JPEG, and share the original file rather than a pasted or forwarded copy.

Why are my screenshots blurry on Windows?

Often because the app was already blurry on screen. Windows renders apps that are not DPI aware at 96 DPI and stretches the result to fit a display scaled above 100%, which Microsoft documents as making the application appear blurry. The screenshot captures that stretched image faithfully. Setting the display back to 100% scaling, or using an app that handles scaling, is what fixes it.

Should I use PNG or JPEG for a screenshot?

PNG. Screenshots are mostly flat color, sharp text, and UI edges, exactly what PNG's lossless compression keeps crisp. JPEG is built for photographs and leaves blocky artifacts around text. See the image-format reference for the full comparison.

Why is my screenshot pixelated after I crop it?

Cropping keeps fewer pixels, so showing that crop at a larger size stretches each one. Capture at full resolution and apply the crop to the original frame, not to the shrunk preview on screen, which has already thrown pixels away.
