Free online batch generator for multi-size App icons and Favicons.

Tool Guide

Tool Overview

The online multi-size icon/image batch generator can batch-generate images of various size specifications from a single large original image, supporting custom sizes, export formats, and automatic scaling, completing multi-size image generation in one click.

When publishing apps or applications, you usually need to upload images/icons of the same picture in different sizes. Making them one by one in Photoshop is too tedious; with this tool, you can generate the various needed sizes in one click - convenient and fast.

By default this tool provides many sizes: 1024, 512, 256, 192, 180, 167, 155, 152, 144, 128, 120, 114, 108, 100, 96, 90, 87, 80, 76, 72, 64, 60, 58, 57, 50, 48, 40, 36, 32, 29, 28, 20, 16, which you can check based on your actual needs.

The final image size result is the sum of the custom sizes and the default sizes; check the default sizes you need, and add custom ones for any not in the defaults.

How to Use

Click to upload or drag an image onto the page; you can also press Ctrl+V after a screenshot to quickly paste and upload an image. Select the sizes to generate, and if a size is not among the defaults, add your needed size in the custom sizes, separated by English commas.

Choose the image format to export, such as JPG or PNG. By default, images are not automatically upscaled; for example, if your original image is 800 pixels, a 1024-wide image will not be auto-generated. If you need to force upscaling, choose force-upscale; upscaled images may be distorted or blurry, so we recommend using a high-definition large image to generate.

The tool supports square or rectangular images. All chosen specifications are widths; the tool automatically calculates the corresponding height based on the actual image ratio, so you only need to set the widths to generate with no height needed. Please check whether your original image's dimensions meet the requirements before generating.

After setup, click the generate button, and the tool automatically generates the chosen sizes and packages them into an archive; click the download button to download all images locally.

This tool is purely front-end browser processing, and your images are never sent to any network server, so you can use it with confidence. It may be incompatible with some older browsers; please use the latest browser version for a better experience.
