Are my images uploaded to any server?

No. Unlike most online tools, Image Tool Bot uses client-side JavaScript to process your images entirely in your browser memory. Your files never leave your device ? no uploads, no servers, 100% private.

Is the service completely free?

Yes! All 20+ tools on Image Tool Bot are completely free with no hidden subscriptions, no registration required, and no watermarks added to your images. We believe powerful tools should be accessible to everyone.

Which image formats are supported?

We support all major web image formats including JPG, PNG, WebP, GIF, BMP, SVG, and ICO. You can convert between these formats seamlessly. Format availability may vary slightly by tool.

Does compression reduce the visible image quality?

Our compressor uses an adjustable quality slider, so you stay in full control. At 80% quality (the default), most users cannot see any visual difference while achieving 60?80% file size reduction. You can preview changes in real-time before downloading.

Does it work on mobile devices?

Absolutely! Image Tool Bot is fully responsive and works great across all modern mobile browsers on both iOS and Android. No app download required ? just open your browser and start editing immediately.

What is WebP? The Modern Image Format for Faster Websites

By Image Tool Bot Team Updated: May 12, 2026 5 min read

If you care about your website's speed and SEO, you need to know about WebP. Developed by Google, WebP is a modern image format that provides superior lossy and lossless compression for images on the web. Using WebP, webmasters and developers can create smaller, richer images that make the web faster.

Why Switch to WebP?

Smaller File Sizes: WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images.
Supports Transparency: Unlike JPEG, WebP supports transparent backgrounds, making it a great replacement for PNG.
Animation Support: WebP can also handle animated images, often with much smaller file sizes than traditional GIFs.
