An ICO converter transforms PNG or JPEG images into ICO format -- the icon format used for website favicons and Windows application icons. An ICO file can contain multiple image sizes (16×16 to 256×256) in a single file, allowing the operating system to display the appropriate size. This tool generates multi-resolution ICO files using the Canvas API, entirely in your browser.

Memahami Format ICO

What is an ICO file and why use it?

The ICO format is a special image container used for favicons (the small icon displayed in browser tabs) and Windows application icons. Unlike PNG or JPEG, an ICO file can contain multiple images at different sizes and color depths within a single file. This allows the operating system or browser to select the most appropriate size for the display context -- a 16×16 version for the browser tab, a 32×32 version for the desktop shortcut, and a 256×256 version for the file explorer.

For modern websites, the HTML tag can reference either an ICO file or a PNG file. Using a PNG favicon is simpler (single size, 32×32 or 192×192) and is supported by all modern browsers. However, ICO files are still recommended for maximum compatibility -- older browsers (IE, old Safari) only support ICO favicons. ICO files are also required for Windows desktop applications and UWP (Universal Windows Platform) apps.

The ICO file format has a simple structure: a header specifying the number of images, followed by a directory of image entries (each with size, width, height, color depth, and offset), followed by the actual image data (which can be in BMP or PNG format). Modern ICO files typically use PNG-encoded image data for sizes above 64×64 (better compression) and BMP-encoded data for smaller sizes (better compatibility). Our tool generates ICO files with PNG-encoded images at multiple sizes.

Favicon best practices

Create a favicon that works at all sizes -- from 16×16 (browser tab) to 256×256 (Windows shortcut). Start with a simple, bold design: a single letter, a simple shape, or a simplified version of your logo. Avoid thin lines, small text, and intricate details that will disappear at 16×16. Test your favicon at 16×16 in a browser tab -- if it's not recognizable, simplify the design. Use high contrast colors that stand out against both light and dark browser tab backgrounds.

For comprehensive favicon support, include: an ICO file with 16×16, 32×32, and 48×48 sizes for legacy browsers; a 180×180 PNG for Apple Touch Icon (iOS home screen); a 192×192 and 512×512 PNG for PWA manifest icons; and a 32×32 PNG as the default favicon. Use the HTML link tags: , , and . Our tool generates the ICO file with multiple sizes from a single source image.

Pertanyaan yang sering diajukan

Mengapa unduhan hanya berisi satu file?
Itulah perilaku yang diharapkan dari format ICO! Anggap file `.ico` seperti file ZIP untuk gambar. Ini berisi beberapa lapisan. Saat Anda memilih 16px, 32px, dan 48px, alat kami menghasilkan ketiga gambar tersebut dan mengemasnya ke dalam satu file `.ico` itu. Browser akan secara otomatis memilih ukuran yang tepat.
Format input apa yang Anda dukung?
Kami mendukung **PNG, JPG, JPEG, WEBP, dan BMP**. Untuk favicon kualitas terbaik, kami sangat menyarankan menggunakan **PNG dengan latar belakang transparan**. Jika Anda menggunakan JPG (yang tidak mendukung transparansi), ikon Anda akan memiliki kotak berwarna solid di sekelilingnya.
Bagaimana cara menginstal favicon?
1. Ganti nama file menjadi `favicon.ico`. 2. Unggah ke direktori root situs web Anda. 3. Tambahkan `<link rel='icon' href='/favicon.ico' sizes='any' />` ke `<head>` HTML Anda.
Ukuran apa yang harus saya sertakan dalam favicon saya?
For standard web compatibility, we recommend including 16x16, 32x32, and 48x48 pixels. The 16x16 size is used for browser tabs on standard-DPI displays. The 32x32 size is used for browser tabs on high-DPI (Retina) displays and for Windows taskbar icons. The 48x48 size is used for desktop shortcuts and Windows Explorer thumbnails. If you need a favicon for older Internet Explorer versions, include 16x16 and 32x32. For maximum compatibility across all platforms (including iOS and Android home screen icons), consider also generating a 180x180 Apple Touch Icon and a 192x192 Android icon using our App Icon Generator tool.
Mengapa favicon saya terlihat buram?
Favicon yang buram biasanya disebabkan oleh salah satu dari tiga masalah. Pertama, gambar sumber mungkin terlalu kecil — jika sumber Anda hanya 16×16 piksel, tidak dapat menghasilkan favicon 32×32 atau 48×48 yang tajam. Kedua, gambar sumber mungkin bukan persegi — ICO mengharapkan gambar persegi. Ketiga, browser mungkin menampilkan favicon dalam konteks yang lebih besar dari yang dimaksudkan.
Bisakah saya membuat favicon animasi?
The ICO format does not support animation. However, you can create an animated favicon using a GIF file and referencing it with `<link rel='icon' href='favicon.gif' type='image/gif' />`. Note that animated favicons are generally discouraged because they can be distracting to users and may impact browser performance, especially when multiple tabs are open. If you want a dynamic favicon, consider using a static favicon that changes based on page state (e.g., showing a notification badge when there are unread messages) by dynamically updating the `<link>` element with JavaScript.
Apakah ada batasan ukuran file?
There is no artificial file size limit. Since the tool processes your image locally using the HTML5 Canvas API and a client-side ICO encoder, the practical limit depends on your device's available memory. Source images up to 4096x4096 pixels are handled without issues on most modern devices. The output ICO file size depends on the number of sizes you select and the complexity of the image — a typical 3-size favicon (16, 32, 48) from a simple logo is 5-15 KB. Very detailed source images may produce larger ICO files due to PNG compression within the ICO container.
Bisakah saya menggunakan alat ini untuk ikon aplikasi Windows?
Yes, but with limitations. Windows application icons (.ico) can contain sizes up to 256x256 with PNG compression for the largest sizes. Our tool supports the standard web favicon sizes (16, 32, 48) and can also generate 64x64 and 256x256 sizes. However, for full Windows application icon support (including multiple color depths and Vista/7/10/11 format specifications), you may need a dedicated icon editor like IcoFX or Axialis IconWorkshop. For web favicons, our tool produces files that are fully compatible with all modern browsers and platforms.
