How to Convert Image Formats
SmarterSources's format converter lets you switch between all major image formats instantly. Whether you need to convert PNG to JPG for smaller file sizes, JPG to PNG for transparency support, or any image to WebP for optimal web performance, this tool handles it all in your browser.
PNG to JPG
Converting PNG to JPG typically reduces file size significantly since JPEG uses lossy compression. This is ideal for photographs and complex images where the visual quality loss is imperceptible. Note that transparency will be converted to a white background.
JPG to PNG
Converting JPG to PNG is useful when you need lossless quality for editing or when working with graphics that require transparency. While the file size will typically increase, no additional quality is lost in the conversion.
WebP Conversion
WebP is a modern format developed by Google that provides superior compression for both lossy and lossless images. Converting to WebP can reduce file sizes by 25-35% compared to JPEG while maintaining equivalent visual quality, making it ideal for web use.
Frequently Asked Questions
Does converting between formats reduce quality?
Converting to a lossy format (JPG, WebP) will involve some quality reduction controlled by the quality slider. Converting to a lossless format (PNG, BMP) preserves all image data. Converting from lossy to lossless won't restore already-lost quality but won't reduce it further.
What happens to transparency when converting?
PNG and WebP support transparency. JPG and BMP do not. When converting a transparent image to JPG or BMP, transparent areas will be filled with a white background.
Which format should I use for my website?
WebP is the best choice for most web images — it offers the smallest file sizes with great quality. If you need broad compatibility with older browsers, use JPEG for photos and PNG for graphics with transparency or text.
Can I convert multiple images at once?
Yes! Drag and drop multiple files or select them with the file picker. All images will be converted to your chosen format and you can download them individually or all at once.
