About the Image Converter
Convert between the most common image formats instantly in your browser. JPEG is best for photographs; PNG for graphics with transparency; WebP for web-optimised images with smaller file sizes. All conversion uses the HTML5 Canvas API — no files are sent to any server.
Frequently Asked Questions
JPEG uses lossy compression. Converting from PNG to JPEG at high quality (92%) is virtually indistinguishable but the file is smaller. Converting JPEG to PNG is lossless but won't recover already-lost detail.
JPEG does not support transparency. Transparent areas are replaced with a white background. Use PNG or WebP output to preserve transparency.
WebP is recommended for modern websites — it's typically 25–35% smaller than JPEG or PNG with the same visual quality. All modern browsers support WebP. Use JPEG for maximum compatibility with older systems.
