WebP vs JPEG vs PNG: Which Format Should You Use?

Image Format Compression Transparency Best For
WebP (Recommended) Lossy & lossless Yes Websites, blog images, photos, graphics
JPEG / JPG Lossy No Photos and images without transparency
PNG Lossless Yes Logos, screenshots, graphics, transparency

For most website images, WebP is a practical choice because it supports efficient compression, transparency, and broad modern browser support. However, the best format depends on the image and how it is used. JPEG remains useful for photos, while PNG is a good choice when lossless quality or transparency is important.

Frequently Asked Questions

What is WebP?
WebP is a modern image format developed by Google for the web. It supports both lossy and lossless compression, as well as transparency, helping reduce image file sizes while maintaining good visual quality.
Are my images uploaded to any remote server?
No. Images are processed locally in your browser and are not uploaded to a conversion server. Your files stay on your device while you resize, optimize, and convert them.
Can I use these WebP images on WordPress, Shopify, or Webflow?
Yes. WebP is widely supported by modern web browsers and can be used on platforms such as Blogger, WordPress, Shopify, Webflow, Wix, Squarespace, and custom websites. Some platforms may process or manage uploaded images differently.
What image width should I choose for my website?
It depends on where the image will be displayed. As a practical starting point, 1200px works well for many featured images and banners, while 800px is suitable for many article images. Use 400px for smaller thumbnails, or keep the original dimensions when resizing is not needed.
Will converting JPG or PNG to WebP reduce image quality?
WebP supports lossy compression, so higher compression can reduce image quality. Start with 80% quality for a good balance between file size and visual quality, then use the preview to adjust the setting if needed.
What happens to transparency when converting PNG to WebP?
Yes. WebP supports transparency. When converting a PNG with a transparent background, the converter can preserve that transparency in the WebP output.
