Blur or Pixelate an Image
Mark only the detail to hide, then blur or pixelate it entirely on your device.
- Runs in your browser — files never leave your device
- Instant — no waiting, no queue
- Fewer clicks, keyboard friendly
Drop an image, click to choose, or paste
JPG, PNG, WebP, GIF, BMP, AVIF, and other browser-readable images
The image is processed in this browser. It is never uploaded.
How to use
- Drop, choose, or paste an image.
- Drag across each face, name, plate, or detail to hide.
- Choose Blur or Pixelate and increase Strength until the detail is no longer readable.
- Select a region to fine-tune its X, Y, width, and height with the keyboard if needed.
- Download the newly rendered image.
Blur and pixelation solve different jobs
Blur softens a selected area and usually blends better into a photo. Pixelation replaces detail with enlarged blocks, making the edit obvious and often better suited to names, account numbers, and number plates. For sensitive text, use a large pixel size, download the result, and inspect the saved file before sharing; a light blur can leave characters distinguishable.
The selection is stored as image-relative coordinates
Each box is saved as a percentage of the image width and height, not as a screen position. That keeps it aligned when the editor scales a portrait, landscape, or high-resolution image to fit the page. You can draw with a mouse or touch, then use the X, Y, Width, and Height fields for a precise keyboard adjustment.
A new file is rendered on your device
The editor uses a reduced preview to stay responsive, then renders the download at the source pixel dimensions. The browser creates a new PNG, JPG, or WebP file without sending the original to Betterbit or a processing server. PNG is lossless; JPG and WebP use a quality setting to trade file size for image detail. Keep the original separately because a newly rendered file does not retain its original metadata.
Frequently asked questions
Does this tool upload my image?
No. Image decoding, blur or pixelation, preview rendering, and download all happen in the browser tab, so the original image is not uploaded to Betterbit.
Which is safer for hiding text: blur or pixelate?
For small or highly sensitive text, strong pixelation is usually easier to verify because it replaces the region with blocks. Increase the value, inspect the saved result, and keep the box slightly larger than the text so edge pixels are covered too.
Can I blur more than one part of a photo?
Yes. Draw a separate rectangle for every area, or use Add region and set its X, Y, width, and height. Undo removes the most recently added area, and Clear regions restores the unedited preview without replacing the source file.
Will the downloaded image keep its original size?
Yes. The effect is rendered at the source image’s pixel width and height; the preview may look smaller only because it is scaled to fit the page.
