Convert images to WebP - the modern format with dramatically smaller file sizes. Cut your page weight by 30-50% while keeping visual quality, improving load speed and Google's Core Web Vitals scores.

Use cases

1. Use case: Optimize web images Convert JPG/PNG images to WebP to cut file size by 25-35% and improve load speed.

2. Use case: Prepare CMS uploads Convert images to WebP before uploading to WordPress or Shopify for smaller media library files.

Practical tips

WebP typically lands 25 to 35 percent smaller than JPEG at comparable quality, but keep your originals — conversion is lossy and one-way. The quality setting is not linear: values in the 75–85 range usually balance size and artifacts, while pushing to 95 doubles file size for little visible gain. Transparency survives the conversion, which is why WebP replaced both JPEG and PNG in many pipelines. Check browser support requirements for older targets before committing a whole library. Like every tool on this site, the Image To Webp runs entirely in your browser: the data you enter never leaves your device, nothing is uploaded to a server, and the tool keeps working if your connection drops.

Common mistakes

Conversion is lossy, so process discipline matters:

  • Discarding originals — conversion is one-way, so always keep the source file.
  • Pushing quality to 95 and above expecting better images: file size roughly doubles for gains the eye barely registers; 75–85 is the practical sweet spot.
  • Converting images that still need cropping or resizing — resize first, then convert, so you do not encode pixels you will throw away.
  • Ignoring the target audience's browser support when older systems are still in play.

Frequently asked questions

Does the Image To Webp send my data anywhere?

No. It runs entirely in your browser — your input is processed on your device and never uploaded. Refresh the page and it still works offline.

How much smaller is WebP than JPEG?
Typically 25 to 35 percent at comparable visual quality, and often more against PNG for flat-color graphics. Actual savings depend on the image: photos compress well, screenshots with fine text less so — compare a few samples before batch-converting a library.
Does WebP keep transparency and animation?
Yes to both: WebP supports an alpha channel (covering PNG's transparency role) and animated WebP (a far smaller alternative to GIF). Transparency survives the conversion, which is one of the format's main advantages.
Why should I use WebP?
WebP is typically 25-35% smaller than JPEG at the same visual quality and supports transparency like PNG. Smaller images load faster and improve Core Web Vitals - Google recommends it for web images.
Which quality should I choose?
Start at 80% - most photos look nearly identical while shrinking significantly. Compare the file sizes before downloading. For screenshots with text, 85-90% keeps edges crisp.
Is WebP supported everywhere?
WebP is supported by all modern browsers (Chrome, Edge, Firefox, Safari 14+) and most CMS/CDN platforms. For legacy clients, keep a JPEG fallback via the picture element.
