About image conversion
Convert between JPG, PNG, and WebP without uploading. Choose the format that fits the job — photos, graphics with transparency, or modern web delivery.
When to use JPG
Best for photographs and everyday images where small file size matters more than perfect fidelity. JPG does not keep transparency.
When to use PNG
Choose PNG for logos, screenshots, and graphics that need crisp edges or a transparent background. PNG is lossless.
When to use WebP
WebP often beats JPG and PNG on size while still supporting transparency, making it a strong default for the web.
Privacy first
Dockzio converts images entirely in your browser with the Canvas API. Your files are never uploaded to a server.
