Can I blur only part of an image?

Yes. Switch to area mode and drag a rectangle over the region to blur.

Does blur change dimensions?

No. Output width and height match the original image.

Is processing private?

Yes. Blur runs on a canvas in your browser with no uploads.

Is this image tool free to use?

Yes. You can use this tool directly in your browser for free, without account creation or hidden upload limits.

Do my files leave my device?

No. Processing happens locally in your browser, so your image files stay on your device and are not uploaded to PictureConvert. Website analytics (not image contents) are described in our privacy policy.

Will the output match the preview?

Yes. The preview is scaled for display, but exports use the original image resolution and the same processing settings you chose.

What this tool does

Apply a controllable Gaussian-style blur to the whole image or a rectangular selection. Preview updates as you adjust strength, and exports keep original dimensions.

Trust and privacy are built into the workflow. Nothing leaves your device during processing, and there is no account setup. That makes it suitable for personal photos, client assets, product shots, and everyday creative work.

How to use Blur Image

Upload or drag your image into the tool above.
Adjust the editing controls until the live preview looks right.
Choose an output format (and quality when relevant).
Download the edited image — processing stays on your device.

Tip: preview at a comfortable zoom, then export once you are happy — repeating lossy saves can add compression artifacts.

Key benefits

Start with a low blur strength and increase gradually
Use area blur to hide faces or text while keeping context
PNG preserves transparency around soft edges
Large images may take a moment to re-blur after each change

Privacy note: no files leave your device. All edit steps run locally in your browser.

Common use cases

Use this to soften backgrounds, redact details, or create frosted effects. Combine with Crop Image when you only need part of a photo.

After you finish, continue with related PictureConvert tools if you need another conversion, compression pass, crop, or metadata step — all without leaving the browser.
