How do I convert an image to WebP online for free?

Why should I convert images to WebP?

WebP is 25–35% smaller than JPEG at the same visual quality. Smaller images load faster, use less bandwidth, and improve Google PageSpeed scores. All modern browsers support WebP including Chrome, Firefox, Safari 14+, and Edge.

Can I convert WebP back to JPG?

Yes. Upload your .webp file and select JPG as the output format. Use this for email attachments, print workflows, and platforms that do not support WebP such as older Outlook clients.

Does Safari support WebP?

Yes. Safari has supported WebP since version 14 (September 2020) on macOS Big Sur and iOS 14. All current iOS and macOS devices display WebP correctly.

Can I use WebP for email?

No. Email clients including Gmail, Outlook, and Apple Mail do not reliably render WebP. Always use JPEG for email attachments and inline images.

Is my image uploaded to a server when converting to WebP?

No. All conversion runs in your browser using the Canvas API. Your image never leaves your device. Safe for sensitive images including ID documents and personal photos.

What Is WebP and Why Convert to It?

WebP is a modern image format developed by Google that provides 25–35% smaller file sizes than JPEG at the same visual quality, and 26% smaller than PNG for lossless images. It supports both lossy and lossless compression, transparency (like PNG), and animation (like GIF). All modern browsers support WebP: Chrome, Firefox, Safari (since 14), Edge, and Opera.

This tool converts JPG, PNG, GIF, and HEIC images to WebP — and converts WebP back to JPG or PNG. All conversion runs in your browser with no server upload.

WebP vs JPEG vs PNG — File Size Comparison

These are typical file sizes for the same 1920×1080px photograph at comparable visual quality:

Format	Typical size	vs WebP	Best for
WebP (lossy)	80–180KB	—	Web images, blog photos, hero images
JPEG (quality 80)	120–280KB	~40% larger	Email, legacy CMS, print workflows
PNG (lossless)	1–4MB	10–20× larger	Screenshots, logos, graphics with transparency
WebP (lossless)	300KB–1.5MB	—	Logos, illustrations requiring exact colors
GIF (animated)	500KB–5MB	2–5× larger	Short animations (WebP animated is smaller)

When to Convert Images to WebP

Use WebP for websites

WebP is the best format for web images — 25–35% smaller than JPEG with identical quality. Use it for blog photos, hero images, product images, and background images. Google PageSpeed Insights flags JPEG and PNG as opportunities and recommends WebP.

Use WebP for WordPress

WordPress 5.8+ supports WebP natively. Upload WebP images directly for smaller files without plugins. For older installs, plugins like ShortPixel or Imagify convert on upload. Converting existing media to WebP reduces total site weight significantly.

Use WebP for Next.js / React

Next.js Image component automatically serves WebP to supported browsers. Upload JPEG originals and Next.js converts at runtime. For static exports, pre-convert to WebP and serve directly for maximum performance.

Avoid WebP for email

Email clients (Gmail, Outlook, Apple Mail) do not reliably support WebP. Always use JPEG for email attachments and inline images. WebP in email is displayed as a broken image in many clients including Outlook on Windows.
