What is this tool
The Image Multi-Size Export tool generates multiple resolutions from a single upload. Pick one PNG, JPEG, WebP, GIF, BMP or SVG file, check the preset sizes (e.g. 16×16, 32×32, 256×256) or add custom width×height rows, then generate only the sizes you selected. Output formats include PNG, JPEG, WebP, SVG, and a combined favicon.ico with several square sizes inside one file. Processing runs entirely in your browser — images are never uploaded. Download files individually or as a ZIP archive.
Use Cases
- 1.Website favicons：Upload a logo, check 16, 32, 48, 256 and export favicon.ico or separate PNGs.
- 2.App & mini-program icons：Produce 512×512, 1024×1024 and other specs from one brand asset.
- 3.Front-end assets：Prepare multiple thumbnails for responsive layouts without repeating export steps in design software.
- 4.SVG scaling：Vector SVG inputs stay vector at each checked size.
- 5.Marketing crops：Export several fixed sizes from one banner for different channels.
Why does this tool exist
Teams routinely need the same artwork at many pixel sizes: favicons, PWA icons, store listings and social crops. Desktop tools mean duplicate artboards or repeated Export As flows — slow and error-prone. Built-in OS utilities resize one file at a time and rarely emit ICO. Many web converters upload files to the cloud. This tool targets the one-image-many-sizes workflow: check the sizes you need, generate once, optionally bundle ICO for browsers, and keep everything local with no install. It cuts icon and asset prep time for developers, designers and site owners.
