Integrated Image Editing

Open a photo or start with a blank canvas to use adjustments, drawing, text, shapes, and searchable stickers within one work history. You can change the entire content or canvas size separately and specify the export pixel size. Zoom in with the mouse wheel, drag while pressing Space to move, and use two fingers to zoom and move on mobile.

Area Mosaic / Blur

You can drag areas to obscure in the photo and adjust the effect intensity. The effect applies based on the original photo, so if areas overlap, the last effect is visible. It does not apply to separately drawn lines or text. For sensitive information, a strong mosaic is recommended over a low-intensity blur. Before downloading, zoom in to check the obscured state.

Batch Processing

Add multiple files and clipboard images to apply resizing and watermarks, and bundle them into a ZIP.

Collage and GIF

Provides downscaled previews equal to the actual output calculation, and GIFs may have simplified color changes due to the 256-color limit.

What is the difference between image size and canvas size?

Changing the horizontal and vertical pixels alters the size of the image itself, while changing the canvas size alters the workspace around the photo. Decide first whether you want to send a smaller photo or add margins to fit a specific ratio.

To remove part of the content, use crop; to blur sensitive areas, use region effects; to insert text or a logo, select the corresponding editing tool. After saving, check the resulting image again to ensure it is the desired size and that no parts meant to be hidden or cropped are left.

Examples and Selection Help

Shrinking a 1600px photo to 800px changes the image itself, while adding margins to a square canvas keeps the photo and changes its surroundings. This tool supports cropping and region effects, but it does not automatically crop subjects or remove backgrounds.

Do I have to manually select the areas to be mosaiced?

Manually select the area to obscure and zoom in on the result to verify. If the effect is weak or only part of the text is selected, the content might still be recognizable. Also, check if the same information remains in other parts of the image.
