What our customers say

People love how great our product works and how we're always there to help

Rated 4.7

"Business pressures now demand almost a 24x7 operation. The difference between choosing one SaaS product or another isn't just down to the technical capabilities of each, but down to their responsiveness when it doesn't quite work. In this case, an issue blocked us from being able to use the platform as intended. Within minutes of using the live chat, the issue was not only reproduced but correctly identified. Within the hour, the hot fix had been coded, tested and applied - unblocking the bottleneck and allowing us to carry on working. This is exceptional and the reason why I can't recommend this company enough - I'm so impressed and very grateful for their hard work. Keep it up!"

"We were looking for tools to help our users create and edit images with templates. We tried options like Canva, but Templated.io turned out to be the perfect choice for our product. It offers an easy API to render images, and its embed editor lets us provide our users with a full editing experience without having to create complex frontend components. It's a really great tool!"

"Brilliant piece of software. Reasonably priced (vs Canva's outrageously expensive API), and despite a few intricacies with the editor, a really fully-featured document generation API. Really great support too from Pedro, the founder!"

"Templated.io is basically a an API-first graphics content designer which makes it super easy to programmatically create document and image assets. It has most basic features and it is robust and "just works". The Make.com app really makes it super simple to incorporate into automation workflows. What sets templated.io apart the most is Pedro and his super fast and service minded, solutions oriented responses."

Blur Image FAQs

Common questions about blurring and pixelating images

Is this blur tool free?

Yes, completely free with no limits. Your images are processed entirely in your browser — nothing is uploaded to any server.

What is the difference between blur and pixelate?

Gaussian blur creates a smooth, out-of-focus effect by averaging nearby pixels. Pixelation creates a mosaic of large colored blocks, making the content unrecognizable in a more obvious way. Both effectively hide sensitive information.

Can I blur only part of an image?

Yes. Select "Draw Regions" mode, then click and drag on the image to draw rectangles around the areas you want to blur or pixelate. You can draw multiple regions and the effect will only apply inside those areas.

Can I undo a region after drawing it?

You can click the "Clear Regions" button to remove all drawn regions and start over. The original image is never modified — the effect is only applied when you click "Apply & Download".

What intensity level should I use?

For hiding text and small details, an intensity of 8-12 is usually sufficient. For faces and larger objects, use 15-25 for a stronger effect. Use the preview to check before downloading.

Are my images uploaded to a server?

No. All processing happens 100% in your browser using the HTML5 Canvas API. Your images never leave your device.

Does this work on mobile devices?

Yes. The tool supports touch events so you can tap and drag to draw blur regions on phones and tablets. Works in all modern mobile browsers.

What image formats are supported?

This tool accepts JPG, PNG, and WebP images up to 50MB. The output is saved in the same format as the original image.
