How It Works
This tool converts images between JPG, PNG, and WebP formats using the browser's Canvas API, handling transparency correctly when converting to or from formats that support it.
Why format choice matters
JPG is best for photos (smaller files, no transparency support). PNG is lossless and supports transparency — best for graphics, logos, and screenshots where sharp edges and transparent backgrounds matter. WebP offers strong compression with optional transparency support and is increasingly used for web images due to smaller file sizes than JPG or PNG at comparable quality.
What happens to transparency
Converting a transparent PNG to JPG fills the transparent areas with white, since JPG has no concept of transparency at all — this is an important thing to check before converting a logo or graphic that relies on a transparent background.
Examples
Converting a screenshot for smaller file size
Converting a PNG screenshot to JPG for a use case where transparency isn't needed and smaller file size matters (e.g. attaching to an email).
Preparing a logo for a website
Keeping a logo in PNG or converting to WebP (rather than JPG) to preserve its transparent background when placing it over a colored page background.
Common Use Cases
- Converting screenshots or photos between formats for compatibility with a specific platform or tool
- Preserving transparency by choosing PNG or WebP instead of JPG for logos and graphics
- Adopting WebP for smaller website image file sizes without a major quality tradeoff
Tips
- If your image has a transparent background you need to keep, avoid converting to JPG — use PNG or WebP instead, both of which preserve transparency correctly.
- WebP typically produces smaller files than JPG or PNG at similar visual quality, but double-check that wherever you're using the image (some older software or platforms) actually supports WebP before relying on it exclusively.
