Frequently asked questions
What is WebP and why use it?
WebP is a modern image format from Google that typically produces smaller files than PNG or JPG at similar quality. Smaller images load faster and improve Core Web Vitals on websites.
Which files can I convert?
You can convert PNG and JPG (JPEG) images to WebP. Drop a single file or a whole batch and convert them all in one go.
Does WebP keep transparency?
Yes. WebP supports transparency, so a transparent PNG converted to WebP keeps its transparent areas. JPG sources have no transparency to preserve.
How do I choose the right quality?
Higher quality keeps more detail at a larger size; lower quality saves more space. For most web images a quality of 75-85% gives an excellent size-to-quality trade-off.
Is my data private?
Completely. Conversion runs entirely in your browser, so images are never uploaded. The tool works offline and nothing is logged or transmitted.
