Mark image areas. Apply one clear effect per area.

The image frame is the coordinate frame

Every area is stored with visible whole-pixel X, Y, width, and height values. Move it, scale it from a corner, or use the numeric fields before you create the result.

Three distinct ways to hide selected detail

The effect belongs to each marked rectangle. A later overlapping rectangle is applied last, so the visible result remains predictable.

From marked area to returned image

The editor keeps the selection state separate from the final processing step so you can review coordinates and effect settings first.

1. 1. Place one source image

   Select a JPEG, PNG, or WebP file within the stated byte and pixel limits.

2. 2. Build the marked-area list

   Drag to create a rectangle, select it, then set its effect and values. Repeat for each relevant area.

3. 3. Check the returned result

   Create the image, read its returned dimensions and format, then inspect the downloaded file where it will be used.

Bounded input and processing checks

The server validates the declared MIME type, matching filename extension, container signature, decoded raster format, pixels, each area, and returned bytes before a result is returned.

• 25 MB — maximum input bytes
• 25 MP — maximum decoded input pixels
• 20 — maximum rectangular areas
• 50 MB — maximum returned output bytes

Review is part of the workflow

Blur and pixelation are visual effects, not a statement about whether content can be reconstructed or accepted for a particular purpose. Check the generated file in its intended setting.

• Compare the returned image with the source
• Confirm every relevant area and selected effect
• Inspect the downloaded file before sharing or publishing
