Image to WebP Converter

How to use

1. Upload image — Drop a JPG, PNG, or any browser-readable image
2. Pick quality — 80% is the sweet spot. Toggle 'maximum quality' for lossless when source is PNG.
3. Convert & download — Save the new WebP file

What Is WebP?

WebP is a modern image format developed by Google that uses more efficient compression than JPG or PNG. At the same visual quality, a WebP file is typically 25–35% smaller than the equivalent JPG and up to 50% smaller than the equivalent PNG. WebP also supports both lossy and lossless modes plus transparency, which means a single format can replace both JPG and PNG in most situations. Every major browser — Chrome, Firefox, Safari, Edge — supports WebP.

Why WebP Matters for SEO and Speed

Image weight is the single largest contributor to slow page loads on most websites. Google uses Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift, Interaction to Next Paint) as a ranking factor. Switching from JPG/PNG to WebP often shaves 1–3 seconds off Largest Contentful Paint with no visible quality difference, which directly improves both search ranking and user experience.

Lossy vs Lossless WebP

• Lossy WebP: The default. Adjustable quality slider — 80% is the sweet spot for photos and most web images.
• Lossless WebP: Preserves every pixel exactly. Useful when converting from PNG and quality is paramount. Files are larger than lossy WebP but still smaller than PNG.

When NOT to Use WebP

If your audience includes a meaningful number of users on Internet Explorer or Safari versions older than 14, you may need to keep a JPG/PNG fallback. For email images, some older email clients still don't render WebP — use JPG for email-embedded images. For print, your printer's RIP software may not accept WebP either; export to PNG or TIFF in that case.

Privacy

The conversion runs entirely in your browser. Your image is decoded, redrawn to a canvas, and re-encoded as WebP using your browser's built-in encoder — no file is uploaded, no tracking pixel fires, and nothing is stored after the page closes.

Frequently asked questions

Why convert to WebP?

WebP is 25–35% smaller than JPG at the same visual quality and up to 50% smaller than PNG, while still supporting transparency. Using WebP on a website is one of the biggest single wins for Core Web Vitals.

Do all browsers support WebP?

Yes. Chrome, Firefox, Safari (14+), and Edge have supported WebP since 2020. Older versions of Safari and Internet Explorer do not, but their combined share is tiny.

Will WebP keep transparency?

Yes. Unlike JPG, WebP supports an alpha channel — transparency from a source PNG is preserved.

What does 'maximum quality' do?

It tells the browser to encode the WebP at quality 1.0, which is visually identical to the source. File sizes are still smaller than the equivalent PNG, but larger than lossy WebP.

Is the image uploaded?

No. Conversion happens in your browser using the Canvas API. The file never leaves your device.
