What is a blurred frame?

A blurred frame keeps your full photo sharp in the center and fills the leftover canvas with a blurred, zoomed copy of the same picture. This page is for any output shape, not only a square. Use a blurred frame when a vertical phone photo must sit on a 16:9 YouTube thumbnail, a landscape photo must fill a 9:16 Story, or you want a soft photo frame without black bars or cropping. The blur frame, photo size, and background zoom update in the preview before you download PNG, JPG, or WebP.

Blurred frame features

Any aspect ratio, not only 1:1

The blurred frame can be 16:9, 9:16, 4:3, 3:4, square, original, or a custom width-to-height ratio. That is the job this page adds beyond the square-only blur on the homepage.

Three live frame controls

Blur sets how soft the edges are. Photo size makes the sharp picture smaller for a thicker frame. Background zoom pushes the blurred copy in so the side blur looks more like color wash than a second copy of the photo.

Keeps the whole photo

The tool contains the original image. Faces, products, and text stay visible. If you want to cut a square out of the picture instead, use the homepage crop mode.

Private browser export

The blurred frame is drawn in your browser. You can process a private photo, download PNG, JPG, or WebP, and close the tab. There is no signup and no watermark.

What is side blur?

Side blur is the same idea as a blurred frame, aimed at the empty left and right (or top and bottom) of a mismatched aspect ratio. TV news, YouTube uploads, and Instagram posts use it when a vertical clip or still has to live on a landscape canvas. Because the fill comes from your own photo, colors match and the edges look intentional instead of padded with black or white bars. This tool builds that side blur photo online: pick 16:9 for landscape, 9:16 for Stories, or Original if you only want a soft border around the current shape.

Why use this blur frame tool

One download instead of a desktop editor

You do not need Photoshop, Canva, or a blur frame generator plugin. Upload, pick a ratio, and download a blur frame photo in the browser.

No black bars and no surprise crop

Platforms often crop or letterbox mismatched photos. A blurred frame lets you choose the canvas first so Instagram, YouTube, or a Story sees the shape you intended.

Colors always come from your image

The fill is a blurred copy of the same photo, so a blur frame PNG or JPG matches the scene instead of dropping in a generic stock border.

Works next to the square tools you already have

Need a strict 1:1 square with no extra frame controls? Use Make Image Square Without Cropping. This page stays focused on side blur and any-ratio frames.

Blurred frame settings and limits

Start Photo size near 80%

A photo size of 75–85% usually shows a clear blurred frame on all sides. Push past 100% only when you want a thin edge.

Raise Background zoom if you see a double image

If the blurred copy looks like a ghost of the sharp photo, increase Background zoom so the side blur becomes broader color, not a second subject.

Match the platform before you export

Use 16:9 for YouTube and presentations, 9:16 for Stories and TikTok covers, and 1:1 for a square post. Custom ratio is for odd print or banner sizes.

This page does not edit video

You can add a blurred frame to a video still or thumbnail. It will not encode a moving side-blur video file.

Best uses for a blurred frame

YouTube thumbnail or 16:9 slide

Drop a vertical still on 16:9, add side blur, and export 1920 or 1280 on the long side so the thumbnail does not show black bars.

Instagram, Reels, and Stories

Use 1:1 for a feed post or 9:16 for a Story. The blurred frame keeps a landscape photo visible instead of forcing a tight crop.

Product and brand photos

A soft blur frame gives a product shot a consistent canvas for a shop grid or ad without stretching the item.

Profile or poster frames

Choose Original or 4:5 custom when you only want a blurred border around the current photo, then download a PNG for a clean edge.
