Frequently Asked Questions
Absolutely. Your privacy is our top priority. This tool processes all your images directly in your web browser using JavaScript. Your files are never sent to or stored on any external server. What happens on your computer, stays on your computer.
Resizing images is crucial for two main reasons: Page Speed and SEO. Large images dramatically slow down your website’s loading time, which frustrates visitors. Search engines like Google also penalize slow websites, ranking them lower in search results. By making your images smaller, you create a faster, better experience for your users and improve your site’s visibility.
- JPEG: Best for photographs. It uses “lossy” compression, which means it reduces file size significantly but can lose some quality. Our tool lets you control the quality level.
- PNG: Best for graphics with sharp lines, text, or transparent backgrounds (like logos). It uses “lossless” compression, preserving all quality but resulting in larger files than JPEG.
- WEBP: A modern format developed by Google. It offers the best of both worlds—excellent compression (even smaller files than JPEG) and support for transparency (like PNG). It’s the recommended choice for web use today.
There are no hard limits set by the tool itself. However, because all processing is done by your computer’s browser, performance depends on your device’s memory (RAM) and processing power. For best results, we recommend processing images in batches of 20-30 at a time, especially if they are very high-resolution files.
Not at all! This tool is completely free to use, with no hidden costs, watermarks, or sign-up requirements. Our goal is to provide a simple and effective utility to help you manage your images more efficiently.
