Blur Image Online

    Blur sensitive areas directly in your browser with circle, rectangle, or freehand pen blur.

    Privacy-first blur editor

    Blur images online with a modern browser-based privacy workflow

    PngExport lets you selectively blur an image in your browser. Use the brush for freehand marks, a circle for rounded details, or a rectangle for text and document fields. The editor exports a PNG from a canvas preview that is capped at 1100 × 720 pixels, so larger source images are downscaled. Blur is a visual mask—not secure redaction for passwords, financial data, or other high-risk secrets.

    Interactive blur preview

    Blur sensitive details fast

    Hide faces, addresses, IDs, plates, chat screenshots, and personal information in seconds before you share an image.

    Choose the right blur style

    Use circle blur for faces, rectangle blur for documents or text, and pen blur for custom areas that need manual control.

    Edit locally in your browser

    The selected image is drawn to a browser canvas for editing instead of being sent to a conversion server by the blur workflow.

    Download a PNG copy

    Prepare your edited canvas as a PNG, review the result, and download it without creating an account.

    What can you blur in an image?

    Search intent for a blur image tool often comes from specific privacy needs. These are some of the most common image elements people want to hide before they post, send, or publish a file.

    Faces and identity details

    Blur faces in street photography, event images, classroom photos, or screenshots before posting online.

    Documents and IDs

    Cover passport numbers, driver license details, invoices, receipts, and account information with a clean rectangle blur.

    Addresses and locations

    Hide home addresses, map pins, street numbers, and delivery labels before sending screenshots or listing images.

    License plates and vehicles

    Blur car plates and identifying details in traffic photos, parking images, real-estate listings, or incident documentation.

    Chat screenshots and UI captures

    Mask profile pictures, names, emails, phone numbers, and private messages before sharing support or product screenshots.

    Mobile-ready content prep

    Quickly blur private information from phone screenshots and social content on desktop or mobile without opening heavy software.

    Three blur methods for different editing jobs

    Different images need different blur behavior. PngExport gives you multiple ways to blur part of an image so you can work faster without forcing one selection style on every task.

    Circle blur

    Best for faces, profile photos, and rounded objects

    Circle blur is ideal when you want a soft, natural-looking mask over a person’s face or another rounded subject. It feels fast and tidy for social content, event photos, and privacy edits.

    Rectangle blur

    Best for IDs, receipts, license plates, and text blocks

    Rectangle blur works well when the content sits inside a structured area. Use it for screenshots, forms, labels, invoices, address blocks, and any detail that needs a straight, controlled blur region.

    Pen blur

    Best for custom shapes and uneven areas

    Pen blur gives you freehand flexibility for irregular shapes. It is useful when the private area is not perfectly circular or rectangular and you want more manual control over the exact blur path.

    Simple workflow

    How to blur an image online with PngExport

    01

    Upload your image

    Open a screenshot, photo, receipt, label, or document image directly in the browser.

    02

    Why it stands out

    Focused editing UI

    The interface is built around quick blur work, so it stays easier to scan than a full design suite.

    Fast privacy prep

    Useful when you need to clean up screenshots and photos before posting to Slack, LinkedIn, X, Instagram, or a support ticket.

    Selective instead of full-image blur

    Only blur the exact area that matters so the rest of the image keeps its context and visual quality.

    Modern browser convenience

    Open, edit, undo, and export from one page without bouncing between tools or installing software.

    How PNG export works

    How PngExport blurs an image in your browser

    Your browser reads the chosen image and draws it onto a local canvas. The blur editor creates a softened canvas copy, then applies it only inside the brush stroke, circle, or rectangle you select. The final canvas is encoded as a PNG for download.

    The image-editing workflow does not send the selected image to a conversion server. The browser canvas is fitted to a maximum of 1100 × 720 pixels; larger source images are downscaled before you edit and export. Keep the original if you need full-resolution output.

    Local image-to-PNG workflow

    1. Read the image

    The selected file is decoded in the browser for the editor preview.

    2. Select a region

    Choose brush, circle, or rectangle and mark the detail to soften.

    3. Apply the blur

    Canvas blends the blurred image into the selected region only.

    4. Export a PNG

    Prepare a PNG from the edited working canvas, then download it.

    Privacy note: local processing describes the image edit itself; it is not a guarantee about normal site hosting, analytics, or network requests.

    Popular image tools to use with blur editing

    Many users blur images as part of a larger workflow. These tools pair naturally with the blur editor for cleaner, lighter, and more polished final assets.

    Best practices

    Tips for better blur image results

    Use circle blur for rounded details, rectangle blur for IDs and text blocks, and the pen for uneven edges.

    Include the full detail and a small margin around it; partial letters or digits can still reveal context.

    Review the exported PNG at full size and check that every intended area was covered before sharing.

    This editor downsizes sources larger than 1100 × 720 pixels. Keep the original for print or full-resolution work.
