Image Format Converter
Convert images between JPEG, PNG, WebP, and BMP formats.
Examples
| Input | Result |
|---|---|
| A PNG screenshot converted to JPEG | JPEG file (transparent areas filled with white) |
| A JPEG photo converted to WebP | WebP file (typically 25-35% smaller) |
| A BMP image converted to PNG | Lossless PNG with much smaller file size |
| A WebP image converted to JPEG for email compatibility | JPEG file viewable in all email clients |
About this tool
Different image formats exist because each one makes different tradeoffs. JPEG is great for photographs but cannot handle transparency and degrades text. PNG is lossless and supports transparency but creates large files for photos. WebP offers the best of both worlds with smaller file sizes, transparency support, and decent quality, but older software may not open it. BMP is uncompressed and mostly useful for legacy compatibility.
This converter draws your image onto an HTML Canvas element and re-exports it in the target format. The process is instant and happens locally in your browser. When converting to formats that support quality settings (JPEG, WebP), you can adjust the output quality to control file size.
Frequently asked questions
What happens to transparency when I convert to JPEG?
JPEG does not support transparency. Any transparent areas in your image will be filled with a solid color (usually white) during conversion.
Which format produces the smallest file?
WebP generally produces the smallest files for both photos and graphics. JPEG is good for photos but bad for sharp edges and text. PNG is lossless and best when you need exact pixel accuracy or transparency.
Does converting between formats reduce quality?
Converting to a lossy format like JPEG or WebP will discard some data. Converting to PNG is lossless, so no quality is lost. Converting from one lossy format to another (e.g., JPEG to WebP) can compound quality loss slightly.
