Free Tool
Image Converter & Compressor
Drop in a JPG or PNG and get back a compressed WebP or AVIF file, right in your browser upload. Nothing is stored on the server. Built for the exact problem that tanks WordPress and Shopify page speed scores: oversized, uncompressed hero and product images.
How It Works
Three Steps, Done
01
Upload your image
Drag a JPG or PNG onto the dropzone, or click to choose a file.
02
Pick format & quality
Choose WebP or AVIF and set a quality level with the slider.
03
Download the result
See the size saved instantly, then download the converted file.
Why It Matters
More Than Just Convenient
- Smaller images directly improve Largest Contentful Paint (LCP), one of Google's three Core Web Vitals.
- WebP/AVIF typically cut file size 25-60% over JPG/PNG with no visible quality loss.
- No plugin install needed to test conversion quality before you commit to a bulk image-optimization plugin.
FAQ
Common Questions
No, this is for one-off conversions and testing quality/savings. For bulk optimizing your whole media library automatically, you still want a plugin like ShortPixel or Smush.
AVIF usually compresses smaller, but not every server can encode it and some older browsers render it inconsistently. WebP is the safer default; AVIF is worth testing for hero images.
No. The file is converted in memory on the server for the request and immediately deleted after it's sent back to you.
