Blur images online free. Gaussian blur with adjustable strength. Works with JPG, PNG, WebP. Instant results.
Sellers sometimes need to obscure a face, house number, packaging barcode, or on-screen chat before posting a product video still or support screenshot. Phone apps bury blur behind subscriptions; desktop editors are slow for a one-off task. Image Blur applies a full-frame Gaussian-style blur controlled by a single slider (1–25px), previewed live, then saved as PNG — all in the browser. It does not include brush-based selective blur or object detection; for partial blur, crop first or use a dedicated editor. Use it when privacy matters more than keeping the background sharp.
Privacy: Processing is designed to run in your browser. Your images are not uploaded to a FastImageTool account.
Image Blur is a free browser tool that softens an entire image by a chosen intensity. People use it to anonymize screenshots before sharing them with customers or teammates, to mute busy backgrounds for mockups, or to create a soft creative look. You upload a common image format, move the blur slider, watch the preview, and download. There is no account requirement and no claim that images leave your device for server processing.
Not with this tool’s current UI. The slider blurs the whole image. For selective privacy edits, crop the sensitive area separately, use a mobile app with a brush blur, or a desktop editor with masks — then return here if you need a uniform soft effect.
Yes. No signup, no watermark. Strength is limited to the 1–25 range exposed on the page. There is no trial wall, daily limit for ordinary catalog prep, or watermark stamped onto the download. If you are preparing Meesho or Amazon India listings, you can process photos one after another in the same browser tab and keep your master originals on disk. We keep the tool free so sellers without a Photoshop subscription can still meet platform image requirements.
Downloads are PNG after processing so the blurred result preserves detail transitions cleanly. Convert to JPG afterward with our PNG to JPG tool if a marketplace rejects PNG After you download, use Image Compressor or a format converter on this site if the destination marketplace prefers JPEG. Always keep the original capture; conversion and compression should start from the highest-quality master you have, especially for zoom-heavy Amazon India images.
