How to Use This Image Converter
Convert images between popular formats directly in your browser. All conversion happens locally -- your images are never uploaded to any server.
- Upload an image in any format by dragging and dropping or clicking the upload area
- Select your desired output format (PNG, JPG, WebP, or BMP)
- Adjust the quality slider for lossy formats (JPG, WebP) to control file size
- Click "Convert" to process the image
- Download the converted image
Tip: JPG and WebP are best for photographs. PNG is ideal for graphics with transparency. BMP is uncompressed and produces large files.
FAQ
What happens to transparency when converting to JPG?
JPEG does not support transparency. Any transparent areas will be filled with a white background during conversion. Use PNG or WebP to preserve transparency.
Is my image sent to a server for conversion?
No. All image processing is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
What is the difference between lossy and lossless formats?
Lossy formats (JPG, WebP) discard some data to achieve smaller files. Lossless formats (PNG, BMP) preserve all image data but result in larger files. The quality slider controls how much data is discarded in lossy formats.
Why is my BMP file so large?
BMP is an uncompressed format that stores every pixel individually. This results in very large files. Consider using PNG for lossless compression or WebP for the best compression.
