Image Converter

The Image Converter supports all major web image formats including JPEG/JPG, PNG, WebP, BMP, and GIF files as input. You can convert between any of these formats, with output options for JPEG, PNG, WebP, and BMP formats.

The tool uses HTML5 Canvas API to process images entirely in your browser. Simply upload an image, select your desired output format, adjust quality settings if applicable, and download the converted file. No data is sent to external servers, ensuring complete privacy and security.

JPEG is ideal for photographs with good compression but no transparency support. PNG offers lossless compression with transparency support, perfect for graphics and logos. WebP provides superior compression with both lossy and lossless modes plus transparency support. BMP is uncompressed with maximum quality but large file sizes.

Convert PNG to JPEG when you need smaller file sizes for photographs or images without transparency. JPEG compression is excellent for photos with many colors and gradients, often reducing file sizes significantly compared to PNG while maintaining good visual quality.

Convert JPEG to PNG when you need transparency support, lossless quality, or have images with sharp edges and few colors like logos, graphics, or screenshots. PNG also prevents quality degradation from repeated editing that can occur with JPEG files.

WebP is a modern image format developed by Google that provides 25-35% smaller file sizes compared to JPEG at equivalent quality levels. It supports both lossy and lossless compression, transparency, and animation. It's ideal for web use as it reduces loading times while maintaining high quality.

Quality settings apply to lossy formats like JPEG and WebP. Higher quality (90-100%) preserves more detail but creates larger files. Lower quality (10-50%) creates smaller files but may introduce compression artifacts. For web use, 80-85% quality typically provides an excellent balance between quality and file size.

Yes, your images are completely secure. All conversion processing happens locally in your browser using HTML5 Canvas technology. No images are uploaded to servers or stored anywhere. Your original files and converted images remain entirely on your device throughout the process.

Currently, the tool processes one image at a time to ensure optimal performance and allow individual quality settings for each conversion. For multiple images, you can repeat the process for each file, customizing settings as needed for different image types and intended uses.

Quality impact depends on the conversion type. Converting from lossy to lossless formats (JPEG to PNG) won't improve quality but prevents further degradation. Converting to lossy formats may reduce quality slightly, especially at lower quality settings. Converting between lossless formats (PNG to BMP) maintains perfect quality.

File size changes vary significantly by image content and format. Converting PNG to JPEG typically reduces size by 50-80%. Converting JPEG to WebP often reduces size by 25-35%. Converting to PNG or BMP usually increases file size but maintains or improves quality. The tool shows size comparison after conversion.

Choose JPEG for photographs and complex images where small file size is important. Choose PNG for graphics, logos, or when you need transparency. Choose WebP for modern web applications requiring the smallest possible file sizes. Choose BMP only when you need uncompressed, maximum quality images for specialized applications.

The tool can handle images up to 10MB in size. However, very large images may require more processing time and could impact browser performance. For optimal performance and user experience, we recommend converting images under 5MB whenever possible.

While the tool processes one image at a time, it's perfect for optimizing images for web use. You can convert each image to WebP format for modern browsers or JPEG for broader compatibility, adjusting quality settings to balance file size and visual quality for faster website loading times.
