About Image Format Converter
The Image Format Converter switches between PNG, JPEG, and WebP directly in your browser with adjustable quality controls and instant file-size comparison. See exactly how much space you save before downloading.
WebP typically offers the best compression (30–50% smaller than JPEG at equivalent quality), making it ideal for web performance. PNG is perfect for images requiring transparency or lossless quality. JPEG remains the most widely compatible format across devices and platforms.
All conversion runs locally using the Canvas API. Your images are never uploaded to any server — safe for converting screenshots, product photos, and proprietary design assets without privacy concerns.
Frequently Asked Questions
Will converting to JPEG lose transparency?
Yes. JPEG does not support transparency. Transparent areas are filled with white. Use PNG or WebP to preserve transparency.
Are my images uploaded to a server?
No. All conversion happens entirely in your browser. Your images never leave your device.
What quality setting should I use?
80–85% is a good balance between file size and visual quality for most use cases. Use 90%+ for high-fidelity output or 60–70% for maximum compression.
Does it preserve EXIF metadata?
No. The Canvas API does not preserve EXIF data (location, camera info, etc.) during conversion. This is actually a privacy benefit.
Can I convert multiple images at once?
Currently the tool processes one image at a time. Upload, convert, download, then repeat for additional files.
