Tips & Tricks
Modern Efficiency
WebP combines the advantages of JPEG and PNG: small files like JPEG with the transparency support of PNG. At similar visual quality it is usually smaller than JPEG.
When to Use WebP
Choose WebP for modern websites and applications where both quality and performance matter. It is the preferred format for Google-optimized pages.
WebP Best Practices
Use WebP as a primary format on modern sites, with a JPEG or PNG fallback. WebP as a format supports both lossy and lossless compression, but this tool writes lossy files — choose PNG output when every pixel must be preserved.

Frequently Asked Questions
Are my images uploaded to a server?
No. All processing runs entirely in your browser via the Canvas API. Your images never leave your device.
What about browser compatibility for WebP?
WebP is supported by every current version of Chrome, Firefox, Edge, Safari and Opera, so an image exported here opens in any up-to-date browser. For older software, serve a JPEG or PNG fallback through the
Is there a file size limit?
Yes, each file must be under 50 MB. There is no fixed limit on how many files you can add, but very large batches take a while because everything runs in your browser tab.
What quality setting should I use for WebP?
Use a high setting (80–95) for photographs you want to keep, and a lower one (40–70) for thumbnails, previews and images that will be displayed small. This tool always writes lossy WebP through your browser's encoder; if you need every pixel preserved exactly, convert to PNG instead.
Can I convert multiple images at once?
Yes. Add as many images as you need — there is no fixed batch limit — then download each file individually or grab them all as a ZIP archive.
Does WebP support animation?
WebP itself supports animation, but this tool converts through the browser's image canvas, so an animated source only yields its first frame. For animated output use a dedicated animation converter; here, treat the input as a still image.
