The conversion process

WebPTools converts images in four simple steps — all of them happen locally on your device:

• Add your images — drag & drop, browse or paste (Ctrl + V). Your files are read straight from disk and displayed as thumbnails.
• Choose your settings — pick the output format, adjust the quality slider and optionally set maximum dimensions.
• Convert — your browser draws each image onto an HTML5 Canvas and re-encodes it in the target format using its built-in image encoder.
• Download — save images one by one, or grab everything at once as a ZIP archive.

What is WebP?

WebP is a modern image format developed by Google in 2010. It uses smarter compression techniques than JPG and PNG, producing files that are:

• 25–34% smaller than comparable JPGs in lossy mode
• about 26% smaller than PNG in lossless mode
• fully supportive of transparency (alpha channel), like PNG
• capable of animation, like GIF

Today roughly 97% of browsers in use support WebP — including Chrome, Edge, Firefox and Safari 14+. For the small remaining audience, websites typically serve a JPG fallback using the HTML <picture> tag (snippet below).

Recommended quality settings

The quality slider trades file size for visual quality. These starting points work well for most websites:

JPG vs PNG vs WebP

For web developers: serve WebP with a fallback

If you run a website, upload both versions and let the browser pick WebP automatically:

<picture>
  <source srcset="hero.webp" type="image/webp">
  <img src="hero.jpg" alt="Describe the image" width="800" height="600">
</picture>

A privacy bonus: metadata is stripped

Every time an image is re-encoded, EXIF metadata — including camera details and GPS location — is removed automatically. The files you download from WebPTools contain clean pixel data only, which is perfect for publishing images online.

Our mission

Most online converters ask you to upload private photos, screenshots and client work to unknown servers. WebPTools was built to prove there is a better way: modern browsers already contain everything needed to convert and compress images — so your files can stay on your device, always.

How it works

Every conversion runs inside your browser using the HTML5 Canvas API. When you drop an image into the tool, it is decoded in memory, re-encoded in the WebP (or JPG/PNG) format and handed straight back to you as a download. No server ever sees a single pixel.

What we believe

Who it's for

Bloggers speeding up their pages, developers optimizing assets, students preparing assignments, shop owners compressing product photos — anyone who wants smaller images without giving up their files.

Found a bug or have an idea for a new tool? We'd love to hear from you — visit the contact page.

1. The short version

WebPTools is a browser-based tool. Your images are converted locally on your device and are never uploaded to any server. We do not require an account and we do not store your files.

2. Image files

All conversion happens inside your browser using standard web APIs. Images you add to the tool remain in your device's memory only until you close or refresh the page. As a bonus, converted files do not contain EXIF metadata (such as camera model or GPS location).

3. Local storage

We save your preferences — chosen format, quality and theme — in your browser's local storage so the tool remembers them next time. You can clear this at any time via your browser settings. This data never leaves your device.

4. Cookies and advertising

WebPTools currently does not use tracking cookies and does not display ads. If advertising is added in the future (for example via Google AdSense), third-party vendors may use cookies to serve ads based on your prior visits to this and other websites. We will update this policy before that happens, and you will be able to opt out via your browser settings or Google Ads Settings.
