Wide Range of Supported Formats: Convert to and from the most commonly used image formats. (See our 'Supported Image Formats' section below for more details).

FastConverter supports a variety of common image formats for input and can convert them to your desired output. Here's a brief overview of the formats we handle:

• JPG (JPEG - Joint Photographic Experts Group): Ideal for photographs and complex images with many colors. Uses lossy compression to achieve smaller file sizes. Does not support transparency.
• PNG (Portable Network Graphics): Perfect for graphics, logos, icons, and images with text or sharp lines. Uses lossless compression and supports alpha channel transparency.
• WEBP (WebP): A modern format developed by Google, offering superior lossy and lossless compression compared to JPG and PNG. Supports transparency and animation. Excellent for web use to reduce file sizes and improve loading times.
• GIF (Graphics Interchange Format): Best known for simple animations. Uses lossless compression but is limited to a 256-color palette. Can also be used for static images with flat colors.
• BMP (Bitmap): An older, typically uncompressed or simply compressed (lossless) format. Often results in large file sizes but is good for storing raw image data. Widely compatible.
• HEIC/HEIF (High Efficiency Image File Format - as input): A modern image format, notably used by Apple devices, that provides high-quality images at significantly smaller file sizes than JPG. Our tool can convert your HEIC/HEIF files to more universally compatible formats like JPG or PNG.

Our tool aims to provide flexibility, allowing you to select the best output format for your specific needs, whether it's for web use, sharing, or further editing.
