Blur Background
Blur the background while keeping a central subject area sharper. A segmentation model can replace this browser fallback later.
How to use it
- Upload a photo with a clear main subject.
- Set blur intensity.

When background blur works best
Blur Background is useful for portraits, product photos, profile images, thumbnails, and quick social graphics where the subject should stand out. The current browser fallback keeps a central subject area sharper and blurs the surrounding image, which works best when the subject is near the middle of the frame.
Use a lower blur for natural depth and a higher blur when the background is cluttered. If the subject is off-center, crop or reposition the photo first with the Image Cropper. For a completely different scene, use Change Photo Background instead.
Review edges carefully
Because this version uses a simple mask rather than full segmentation, hair, shoulders, hands, and transparent objects may not separate perfectly. Check the preview at normal size and look for blur crossing into the subject. If the image needs precise portrait separation, save this as a draft and finish in a specialist editor.
Background blur can also hide distracting private details in a room, but it is not a secure redaction method. For readable text, faces, addresses, or license plates, use Pixelate Image so the sensitive area is intentionally obscured.
Blur a photo background without Photoshop
Upload a portrait or centered photo, set the blur intensity, and preview the result in your browser. The tool applies a central oval mask that keeps the subject sharper while softening the surrounding area, which is the most common background-blur workflow for profile photos, thumbnails, and product shots.
Photoshop and similar editors provide layers, masks, subject selection, and lens-blur filters that produce more precise separation around hair, glasses, and transparent edges. This browser tool does not perform AI subject detection, does not offer selective focus or bokeh simulation, and cannot export layered files. Use it for a quick local preview before committing to a desktop editor, or for images where a soft oval mask is acceptable.
For a completely different background, try Change Photo Background. For pixel-level redaction of text or faces, use Pixelate Image instead of blur.
Blur a PNG image background
Upload a PNG or any browser-readable image, set the blur intensity, and download a blurred-background PNG. The tool preserves the output format as PNG so transparency and crisp edges are retained. Use this for portrait backgrounds, product photos, social graphics, and privacy-safe sharing.
For precise subject isolation, the oval mask works best with centered subjects. For complex edges or multiple subjects, use the Background Remover for a transparent cutout, then add a blurred version behind it. Read the background removal guide for more on edge quality and workflow options.
Blur a face in a photo
To blur a face for privacy, upload the photo to the blur tool above, set a high blur intensity, and position the oval subject mask over the face area. The mask applies heavy Gaussian blur to everything outside the oval, keeping the face region relatively sharp.
For face-specific blurring, use the blur tool with maximum intensity and move the subject mask to cover only the face. Download the result as PNG. This approach works for profile photos, screenshots, and social media posts where facial privacy is needed. Related tools: Background Remover, Change Background, Add Watermark.
