Blur Image Online
Blur JPG, PNG and WebP images locally in your browser. Apply full-image blur, keep dimensions and format, and download individual files or a ZIP without uploading images.
What this tool does
NexKit Blur Image applies a full-image blur to supported JPG, PNG, and static WebP files directly in your browser. One blur intensity is applied to the current image batch.
The output keeps the original browser-decoded width and height. JPEG stays JPEG, PNG stays PNG, and WebP stays WebP when the browser supports Canvas encoding for that format.
How to blur images
Open the Blur Image page, choose one or more supported images, then set the blur intensity. Run the tool to create real blurred image pixels, not just a CSS preview.
After processing, download each successful blurred image individually or package successful outputs as a ZIP file generated locally in the browser.
Supported formats and scope
This release accepts JPEG, PNG, and static WebP images. GIF, SVG, HEIC, HEIF, AVIF, TIFF, BMP, animated image workflows, and unknown formats are rejected.
This MVP blurs the entire image. Brush blur, rectangular blur, face detection, background blur, portrait segmentation, motion blur, and AI blur are not part of this release.
Privacy and local processing
Images are blurred locally in your browser for this tool. NexKit does not upload selected images, generated image blobs, source filenames, or image contents to a server for this workflow.
Canvas re-encoding usually removes original EXIF, GPS, ICC, and other metadata. Transparent PNG and WebP files keep alpha where the browser supports alpha output; blur can naturally create semi-transparent pixels near opaque edges.
Frequently Asked Questions
Are my images uploaded?
No. Blur Image processes supported images locally in your browser. The selected files and generated outputs are not uploaded to NexKit servers by this tool.
Which image formats are supported?
This MVP supports JPEG, PNG, and static WebP images. GIF, SVG, HEIC, AVIF, TIFF, BMP, animated formats, and unknown formats are rejected.
Does blurring change image dimensions?
No. Blur Image keeps the browser-decoded width and height unchanged. It does not resize, crop, stretch, pad, or rotate images.
Can I blur multiple images?
Yes. One shared blur intensity is applied to all selected images, and successful outputs can be downloaded one by one or together as a ZIP.
Does the output keep the original format?
Yes. JPEG stays JPEG, PNG stays PNG, and WebP stays WebP when the browser supports Canvas encoding for that format.
Is PNG transparency preserved?
Yes. PNG and WebP alpha is preserved through the browser Canvas workflow. Blur can naturally create semi-transparent pixels around opaque edges.
Can I blur faces or only part of an image?
No. This MVP applies one full-image blur. Brush blur, face detection, background blur, and AI blur are reserved for future work.
Does this preserve EXIF metadata?
No. Canvas re-encoding usually removes original EXIF, GPS, ICC, and other metadata. The output is a newly encoded blurred image.
