Convert images to and from WebP format
WebP delivers 25–35 % smaller files than JPEG and PNG at comparable quality — making it the go-to format for fast-loading web pages. Convert to WebP for your site, or convert WebP files back to JPEG/PNG when you need universal compatibility.
Use this tool freeFeatures
Two-way conversion
Convert JPEG or PNG to WebP to shrink file sizes for the web, or convert WebP back to JPEG/PNG when you need a format that every app and device supports.
Lossy and lossless modes
Choose lossy compression for photographs (smaller files, slight quality trade-off) or lossless compression for graphics and screenshots (pixel-perfect, larger files).
Quality and effort controls
Fine-tune output quality from 1 to 100 and set the compression effort level from 0 (fast) to 6 (smallest file). Defaults of quality 80 and effort 4 balance speed and size.
Batch processing
Convert up to 25 images in a single session. Results download individually or as a consolidated ZIP archive.
How to use
Choose conversion direction
Select whether you want to convert to WebP or from WebP to JPEG/PNG using the toggle at the top of the tool.
Upload images

Adjust settings
Pick lossy or lossless mode, set the quality slider, and choose the compression effort level.
Convert and download
Click Convert, review the file-size savings in the results panel, and download your new files.

Common questions
Do all browsers support WebP?
+
As of 2024, WebP is supported by Chrome, Firefox, Safari, Edge, and Opera — covering over 97 % of global web traffic. Internet Explorer does not support WebP, but its usage share is below 0.5 %.
How much smaller is WebP compared to JPEG?
+
Google's studies show WebP lossy images are 25–34 % smaller than JPEG at equivalent visual quality, and WebP lossless images are 26 % smaller than PNG.
Should I use lossy or lossless WebP?
+
Use lossy for photographs where a slight quality trade-off is acceptable in exchange for much smaller files. Use lossless for UI elements, screenshots, and any image where pixel-perfect accuracy matters.
Boost quality after conversion
Converting formats does not improve the underlying image. Run your WebP or JPEG through AI Enhance to sharpen details, correct exposure, and bring photos to life.
