Choose 16×16 or 256×256? How to pick the right size for ICO icons

When creating icons for websites or apps, many people struggle to choose the right size, as icon requirements vary greatly across different scenarios. For example, a 16×16 pixel size is enough for small icons in browser address bars, while a 256×256 or even 512×512 size is needed for app launch page main icons to avoid blurriness. Many people don’t know that online tools let you select these sizes directly, so you don’t have to adjust sizes yourself using Photoshop, saving a lot of effort.

Besides these two extreme sizes, there are intermediate options: 32×32, 48×48, 64×64, and 128×128, which cover all common sizes from browser bookmarks, mobile home screens to app store display images. You don’t have to crop images repeatedly; just select the corresponding size and click, which is much more user-friendly for beginners, eliminating the need to worry about pixel conversion.

Upload PNG, JPG or GIF? Choose the right image format to avoid wasted effort

Many people, when using an ICO generator for the first time, upload any image randomly, only to either upload an unsupported format or an image that doesn’t meet requirements, wasting effort. In fact, this online tool only accepts three formats: PNG, JPG, and GIF, which are the most commonly used image formats in daily life, so you will hardly encounter format issues. No need to convert formats in advance; just drag and drop the file.

If you want to create ICO icons with transparent backgrounds, the original PNG format image works best, as PNG supports alpha transparency. After uploading, you don’t need to do extra matting; once you select the size, the generated icon will have a transparent effect, with no white borders when used on websites or apps. JPG images, though not supporting transparency, have the advantage of small file size, making them suitable for small icons that don’t need transparency, such as desktop shortcut icons. GIF images can be used occasionally, for example, if you want a small animated icon, but static formats are more practical for most scenarios.

Round corners first then generate? Two options to optimise icon effects

Before generating ICO icons, there’s a small detail that affects the final effect – whether to add transparent rounded corners first. This tool has a built-in online transparent rounded corner tool, adding an extra optimisation option, so you don’t need to go to another website to handle rounded corners. If using this tool, after uploading the image, you can click the rounded corner tool to adjust parameters, such as the corner radius, generate a transparent image with rounded corners, then convert to ICO. The resulting icon will be more refined than converting directly, suitable for websites or apps that require high attention to detail.

If you’re in a hurry, you can just select the size and click generate; the tool will automatically convert the image to standard ICO format, with the default saved filename being favicon.ico. No need to change the name yourself; just upload it to the website root directory and it’s ready to use. This default naming is industry-standard, so there won’t be issues with icons not displaying due to incorrect filenames, saving a lot of trouble for beginners.

For beginners or designers? The suitable scenarios for this tool

Some people ask, is this tool for beginners or designers? Actually, it works for both. Beginners don’t need to understand complex image processing; just upload, select size, and click generate – three steps to finish. There are no complicated operation buttons, and the interface is clean. Designers can also use it for quick format conversion, no need to open Photoshop for simple conversions, saving time. Moreover, it supports all sizes, so you don’t have to adjust canvas size yourself, making it suitable for when you’re rushing a project.

Whether you’re a student just making a website or a designer working on an app, this tool’s features cover all common needs, so you don’t have to look for other tools to convert formats back and forth. After all, many online tools either support few formats or have incomplete sizes, but this tool covers all commonly used ones, and the operation is barrier-free – you can start using it without spending time learning.
