About Image Format Conversion
Convert between JPG, PNG and WebP. JPEG suits photos, PNG suits images with transparency, and WebP gives the smallest size. Conversion runs locally in your browser — images are never uploaded to a server. To reduce file size, use the image compressor.
Format Conversion Use Cases
Web performance: converting PNG to WebP cuts size by 25–35% while keeping quality; Compatibility: some older systems don't support WebP, convert back to JPEG/PNG; Transparency: converting a transparent PNG to JPEG automatically fills the background white; Batch conversion: upload and convert repeatedly to suit different scenarios.
FAQ
What are the differences between JPEG, PNG and WebP?
JPEG uses lossy compression and suits photos and images with rich gradients; PNG is lossless and supports an alpha channel, suiting icons and screenshots; WebP balances small size and high quality and is the recommended format for modern web pages.
Are converted images uploaded to a server?
No. Conversion is done locally in your browser via the Canvas API; your image data never leaves your device.
Will the image dimensions change after conversion?
The width and height stay the same — only the file format and encoding change. To change dimensions, use the image resizer.
What happens to a transparent background when converting PNG to JPEG?
JPEG does not support an alpha channel, so transparent areas are filled with a white background. To keep transparency, convert to PNG or WebP instead.
