ICO

Icon File

The .ICO filename extension refers to the ICON image file format originally developed by Microsoft. The extension is used to represent computer icon images of varying sizes designed for the operating system Microsoft Windows. Its use today has extended to developing icons for programs designed using the Microsoft developer's suite Visual Studio and other applications. Similar to other device independent bitmap file formats, the ICON file format is also in the raster graphics class of image formats where each individual pixel is part of an orthogonal dot matrix data structure with support for a limited palette of color information. As a resource file, the .ico file format has its strength in contextual use. This allows for multiple icon images of different color depth or size to be stored within the resource file and used when appropriate.
HEIC

High Efficiency Image Container

HEIC (High-Efficiency Image Container) file format stores images and image sequences. This file format was developed by the Moving Picture Experts Group (MPEG) and it uses High-Efficiency Video Coding (HEVC) compression. HEIC files are known for storing high-quality images with a smaller file size as compared to other image formats, for example, JPEG.

Trusted conversion quality

FreeFileConvert uses tuned encoding for ICO to HEIC conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.

Seamless workflow

Upload ICO files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized HEIC results on any device you rely on.

Batch support for teams

Process up to 5 files sized 600 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent HEIC audio with dependable progress tracking.
