What is WebP
WebP is an image format announced by Google in 2010. Based on the VP8 video codec technology, it achieves significantly smaller file sizes compared to traditional JPEG and PNG. With lossy compression, WebP is 25-35% smaller than JPEG. With lossless compression, it's 26% smaller than PNG. It also supports transparency (alpha channel) and animation.
Compared to JPEG & PNG
JPEG: Ideal for photographs. Achieves high compression ratios, but quality degrades with each re-compression (lossy). Does not support transparency. PNG: Ideal for illustrations and screenshots. Lossless compression preserves quality perfectly, and supports transparency. However, file sizes are larger than JPEG. WebP: Combines JPEG's high compression with PNG's transparency support. 25-35% smaller than JPEG at the same quality, and 26% smaller than PNG with lossless compression.
How to Convert
Simply drag and drop your JPEG or PNG images to convert them to WebP. Adjust quality with the slider and batch download multiple files as a ZIP archive. All processing happens in your browser — images are never uploaded to any server.

FAQ
- What is WebP?
- WebP is an image format developed by Google. It achieves 25-35% smaller file sizes than JPEG and PNG at equivalent quality. It supports both lossy and lossless compression, as well as transparency (alpha channel).
- Which browsers support WebP?
- As of 2026, over 99% of major browsers support WebP, including Chrome, Firefox, Safari, and Edge. Only legacy Internet Explorer cannot display WebP images.
- WebP vs JPEG — which is better?
- WebP is superior in file size (25-35% smaller at the same quality). However, JPEG is safer for print use or maximum compatibility. For web and blog images, WebP is recommended.
- How do I convert WebP back to JPEG or PNG?
- This DevPick tool currently supports JPEG/PNG → WebP only. For reverse conversion, use online tools like Squoosh or iloveimg, or open the WebP file with macOS Preview / Windows Paint and save as JPEG/PNG.
- How do I use WebP with WordPress?
- WordPress 5.8+ supports WebP uploads natively. For bulk conversion of existing JPEG/PNG images, plugins like EWWW Image Optimizer, Imagify, or ShortPixel work well. For manual workflow, use this tool to convert before upload.
- Does WebP improve SEO and Core Web Vitals?
- Yes. Smaller files improve LCP (Largest Contentful Paint), a Core Web Vitals metric used by Google for ranking. PageSpeed Insights recommends WebP as 'next-generation image format'.
- How much quality is lost when converting to WebP?
- Quality 80 (recommended) produces files 25-35% smaller than JPEG with visually identical quality. Quality 100 enables lossless compression with zero quality loss but smaller file size reduction. Web use typically benefits from quality 75-85.
- What image formats are supported? Are there size or count limits?
- JPEG and PNG inputs. Up to 20 files at once, max 50MB per file. All processing happens in your browser — images never leave your device.
