Image Blur Effects

Adding a blur effect to your screenshots can serve multiple purposes, from protecting sensitive information to enhancing the visual focus on specific areas of the image. With adjustable blur radius, you can control the intensity of the effect to meet your requirements.

Need format guidance? See the PNG vs JPEG format guide and the website screenshot API for automation.

Use Add Screenshots blur filters to anonymize data, highlight target content, or prep assets for public sharing—all while routing captures straight to your storage.

Apply Blur for Free or Compare Plans

• Privacy at scale: Mask sensitive UI before distribution without manual editing.
• Automation-ready: Store blur settings in request templates and run via schedules or webhooks.
• Direct delivery: Export blurred images to AWS S3, Azure, Google Cloud, or Cloudflare R2.

Adjusting Blur Radius

The blur radius can be adjusted between 0 and 100 pixels. A higher radius results in a stronger blur effect.

The default blur is 0 pixels, meaning no blur is applied to the screenshot.

Best Practices for Blurring

• Mask selectively: Pair blur with section captures or element hiding to reveal only the context you need.
• Create anonymized archives: Save blurred images to AWS S3 or Azure with dynamic file patterns for compliance teams.
• Combine with color filters: Use blur alongside brightness, contrast, or grayscale adjustments to keep assets brand-ready.
