No re-upload neededThese tools accept .JPG - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Blurring an image blends each pixel with its neighbours, taking back fine detail and hard edges. This tool uses an even box blur whose strength is chosen automatically from the image size, so the effect is clearly visible yet not overdone on small thumbnails and large photos alike.
A soft blur is useful to push a background back, make sensitive detail less prominent before sharing, create a gentle bokeh look, or provide a calm area for text placed on top. The output keeps your original format and dimensions - a PNG stays a PNG (with transparency), a JPEG stays a JPEG.
Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. Honestly framed: blurring is a visual effect, not secure redaction; a blurred area can sometimes be partly reconstructed with effort, so for true redaction remove the content entirely. Animated images are flattened to a single frame.

Limitations: Blurs an image with an even box blur; the strength is derived automatically from the image (about a hundred-and-tenth of the shorter side). The original format and dimensions are preserved (PNG keeps transparency; JPEG flattens onto white). Animated inputs are reduced to a single frame. It is a visual effect, not secure redaction.
No. The effect runs entirely locally in the browser on a canvas - even offline. Your image never leaves your device.
No. It is a visual effect and can be partly reversible with effort. To truly remove sensitive content, delete it from the image rather than only blurring it.
The strength is chosen automatically from the image (about a hundred-and-tenth of the shorter side), so the softness is visible yet balanced at any size.
Yes. A PNG stays a PNG (with transparency), a JPEG stays a JPEG, and the dimensions are unchanged.
