Convert your images
The free Vivlab image converter turns your files into WebP, PNG or JPEG, right in your browser. Your images never leave your computer.
Load an image, pick the output format, then download the result or copy its base64 data-URI.
Choosing the right image format
PNG, JPEG or WebP?
PNG keeps transparency and stays lossless, which makes it perfect for logos and crisp graphics. JPEG compresses photos heavily and suits images packed with colour. WebP blends the best of both: efficient compression, with or without transparency.
When to use each one?
Go with PNG for a logo or a screenshot, JPEG for a photo headed for everyday use, and WebP to lighten your web pages without giving up quality. Converting a file lets you fit it to each purpose.
The base64 data-URI
A data-URI encodes your image straight into text (base64). Pasted into HTML or CSS, it embeds the image with no separate file: handy for small icons or an email, best avoided for large visuals that would bloat your code.
The Vivlab tip
Before exporting, compare the "before / after" file size: for a photo, WebP at roughly quality 80 often strikes the best balance between a light file and a sharp look. Keep PNG for images that genuinely need transparency.
