FAQ

Frequently Asked Questions

Is my image uploaded to your servers when I pixelate it?

No, never. Image Studio uses advanced client-side technology to process your images directly inside your browser. Your files never touch our servers, ensuring 100% privacy and security.

Can I pixelate only a specific part of an image, like a face or a logo?

Yes! You can use our manual brush tool to paint over specific zones like eyes or documents, or use rigid rectangular and elliptical selection tools to cleanly pixelate targeted areas.

What does the pixel aspect ratio setting do?

While standard pixelation uses perfect squares, the aspect ratio option allows you to stretch the pixel blocks horizontally or vertically. This is ideal for creating unique stylistic textures or matching specific design layouts.

Are there any limits on image size or the number of files I can process?

No. Unlike other online tools that restrict file sizes, require paid subscriptions, or throttle your speed, Image Studio is completely free, supports high-resolution files, and has no daily usage limits.

How to pixelate images step by step

Censor sensitive information or stylize your photos directly in your browser. This tool provides precise block sizing, aspect ratio flexibility, and shape-restricted pixelation without sending your images to external servers.

1Open the pixelate tool

Start by navigating to the Pixelate Image workspace. The tool operates locally on your machine, using high-performance rendering pipelines to process block-style censorship and stylized effects without compromising file privacy.

2Upload your target image

Click the file picker to select and load your image into the workspace. The tool supports standard image formats, automatically preparing the pixels for downscaling and block-rendering operations.

3Adjust block dimensions and aspect

Define the block width and height to control how abstract or recognizable the pixelated blocks will be. By default, the aspect ratio is locked to produce perfectly square blocks, but you can unlock it to stretch blocks horizontally or vertically for specialized artistic styling.

4Isolate pixelation with rigid shapes

Instead of pixelating the entire image, select a Rectangle or Ellipse shape to focus the effect. Use the coordinate fields to place and size the selection window, cleanly confining the pixelation grid inside the defined boundaries.
