Blur Photo Online

1. Open the image

   Press "Choose image", drag the file onto the page or paste it with Ctrl+V. With "Try a sample photo" you can test the effect without digging through your phone.

2. Set the Blur

   The slider runs from 0 to 30 px and starts at 6: low values just soften the scene, while beyond 15 px the image turns almost abstract. The preview reacts in real time.

3. Download when the effect feels right

   "Undo" removes the blur in one click if you want a clean slate; "Download" exports the blurred version, free and with no watermark.

The smartest use of blur isn't hiding things — it's preparing them. A photo blurred between 8 and 15 px becomes the perfect backdrop for titles, quotes, presentation slides and website hero sections: the colors and mood of the original remain, but no detail competes with the text in front.

The typical flow takes two moves: blur the image here, then head to the add text to photo tool and drop in your message with the font and color of your choice. It also works for elegant phone wallpapers: a personal photo blurred at 10–12 px sits in the background without distracting from the icons. Try several strengths — text legibility improves noticeably just going from 6 to 10 px.

A light blur is great for pushing distractions into the background: the clutter behind a hastily photographed product, a recognizable poster on the wall, a glowing screen in the corner. The eye slides past them and the subject wins the attention.

It's a different story if you need to censor sensitive information — license plates, documents, addresses, strangers' faces. There, blur isn't the safest choice: if it's light, reconstruction techniques can recover part of it. For true anonymization, use the photo pixelation tool with large blocks, which destroys the information far more radically. Rule of thumb: blur for aesthetics, pixelate for content privacy.

With as little as a 2–4 px radius you get the classic dreamlike look: outlines still readable, but wrapped in the softness of a memory or a dream. It's a device cinema has always used for flashbacks, and on a portrait it instantly creates a romantic mood. A few ideas to start from:

• Music cover art: a photo blurred at 10 px makes a perfect abstract base.
• Memory effect: 3 px on a family photo, for a nostalgic tone.
• Textures for websites and invitations: 20–30 px turn any shot into washes of color.

To steer the eye even further, pair it with a vignette around the edges: blur plus darkened corners is the duo that pulls attention to the center.

The blur applied here is Gaussian: each pixel is replaced by a weighted average of the pixels around it, with weights that follow the famous bell curve — close neighbors count more, distant ones less and less. The pixel radius you set with the slider defines how wide that bell is, and therefore how much the image softens.

One practical implication: the radius is absolute, so 10 px on a 4000-pixel-wide photo is far less noticeable than on the same photo scaled down to 800. Always judge the effect at the final display size. The entire computation stays confined to your browser tab — the photo is never uploaded anywhere — and the Canvas export also strips the EXIF metadata, including the date and location of the shot: one more detail working in your favor.

• Start from the preset 6 px and adjust by eye.
• Always keep a copy of the original.
• Judge the effect at the size you'll actually use the image.
