Why Resize WebP Images?
WebP is rapidly becoming the standard for web images. Resizing your WebP files helps you:
- Maximise web performance — WebP files are already smaller than JPG, and resizing to display dimensions reduces them further.
- Optimise for mobile — Smaller images mean faster loads on mobile networks, improving user experience and reducing bounce rates.
- Maintain transparency — Unlike JPG, WebP supports alpha transparency, making it ideal for overlays and UI elements.
- Reduce CDN costs — Smaller assets mean lower bandwidth bills, especially at scale.

Frequently Asked Questions
- What is WebP and why should I use it?
- WebP is a modern image format developed by Google. It produces files 25–35% smaller than JPG at comparable quality, and supports both lossy and lossless compression plus transparency. It's supported by all modern browsers.
- Can I resize WebP images without losing quality?
- Yes. When using lossless WebP or setting the quality slider to 90%+, the visual difference from the original is imperceptible. For best results, start from the highest-quality source available.
- Do all browsers support WebP?
- Yes — Chrome, Firefox, Safari, Edge, and Opera all support WebP. The only exceptions are very old browser versions (Safari before 14, IE11). For maximum compatibility, you can also resize as JPG or PNG.
- Is WebP better than JPG?
- For web use, generally yes. WebP achieves 25–35% smaller file sizes at equivalent visual quality, supports transparency, and supports both lossy and lossless modes. JPG has slightly broader compatibility outside of browsers (e.g., older photo editors).
- Can I resize multiple WebP files at once?
- Yes. Drop all your WebP files at once and resize them in a single batch. Use our image resizer for ZIP download of large batches.
