Is this blur and pixelate tool really free?

Yes. Blurring or pixelating your images is completely free, with no watermark, sign-up, or file limit beyond the batch size shown in the tool.

What's the difference between blurring the whole image and selective regions?

Whole-image mode applies one blur or pixelate effect across the entire photo. Selective mode lets you draw one or more rectangle or ellipse regions — like a face or a license plate — and blur or pixelate only those areas, leaving the rest of the photo untouched.

Can I redact multiple faces or objects in one photo?

Yes. Draw as many regions as you need in selective mode, each with its own shape, effect type, and strength, then clear or delete individual regions at any time before downloading.

Can a blurred face be recovered?

It depends on the strength. A light blur can still leave enough detail behind that a face or plate is recoverable, especially with modern image-restoration techniques, so it is not a safe redaction on its own. This tool ties strength to a percentage of the photo's shorter side rather than a fixed pixel count, so you can push it high on any image size — for genuine redaction, use a strength well above the default and check the result closely before sharing.

Why is the strength shown as a percentage instead of pixels?

A fixed pixel amount looks strong on a small preview but can become weak once applied to a large, full-resolution photo. Using a percentage of the image's shorter side keeps the effect consistently strong regardless of the original photo's dimensions.

Should I blur or pixelate for redaction?

Pixelating tends to look more obviously and completely obscured at a given strength, which can make it a safer default for redaction, while blur can look more natural for stylistic use. If you specifically want a strong, uniform mosaic effect across an entire image, the dedicated image-mosaic tool is built exactly for that.
