JPG vs WebP
JPG (also called JPEG) is the most widely supported photo format on the planet. It uses lossy compression to keep files small, which makes it perfect for photos — but it does not support transparency.
WebP is a modern format created by Google. It supports lossy and lossless compression plus transparency, and is typically 25–35% smaller than JPG or PNG at similar visual quality. Some older apps and upload forms still refuse it.
Frequently asked questions
Is it safe to convert JPG to WebP here?
Yes. Conversion happens entirely inside your browser, so your images are never uploaded to a server and nobody else can see them.
Will converting JPG to WebP reduce quality?
WebP uses lossy compression. At the default quality setting (90) the difference is practically invisible. Lower the slider for smaller files, or raise it to 100 for maximum quality.
What happens to transparency?
WebP supports transparency, so transparent areas are preserved.
Can I process many images at once?
Yes. The free version handles up to 20 images per batch, and you can download them all as a single ZIP file. ToolSmith Pro removes the limit.
Does it work on my phone?
Yes. It works in any modern browser on Windows, macOS, Linux, iPhone, iPad and Android — there is no app to install.
