No, there are no limits on usage. You can use our tools as many times as you want, process as many images as you need, and come back as often as you like. There are no daily limits, no file count limits, and no time restrictions.

No, absolutely not. All processing is done locally in your browser using JavaScript and HTML5 Canvas. Your images never leave your device. We never see, store, or have access to your images. This is our core privacy promise.

No, we do not store or share your images. Since all processing happens locally in your browser, we never receive your images. There's nothing to store or share. Your privacy is completely protected.

Yes, it's completely safe. Since your images never leave your device, you can safely use our tools for sensitive documents, personal photos, or confidential images. There's zero risk of data breaches or unauthorized access.

We support three major image formats: JPG/JPEG (best for photographs), PNG (best for images with transparency), and WebP (Google's modern format with excellent compression). You can upload and convert between these formats using our tools.

The maximum file size is 10MB per image for single processing tools. For batch processing, each image must be under 5MB. This ensures smooth processing in your browser without performance issues.

Our compression algorithms reduce file size by optimizing image data while maintaining visual quality. For JPEG and WebP, we use lossy compression that removes some data to reduce size. For PNG, we use lossless compression that preserves all data. You control the balance between file size and quality using our slider or target KB presets.

Yes, our Batch Image Tools allow you to process up to 10 images at once. You can compress, resize, convert, flip, or rotate multiple images with a single click. Each image in the batch must be under 5MB.

Yes, all our tools are fully responsive and work on all devices including smartphones, tablets, and desktops. The interface adapts to your screen size for the best experience.

WebP is the best format for web images. It offers 30% better compression than JPEG at the same quality, resulting in faster loading websites. However, JPEG is still widely supported and great for photographs. PNG is best for images with transparency or text.

It depends on the compression settings. Higher compression (smaller files) will reduce quality more. You can control this balance with our quality slider. For PNG compression, there's no quality loss (lossless compression). For JPEG and WebP, you can choose the quality level that works best for you.

There's no difference. JPG and JPEG are the same format. JPEG stands for "Joint Photographic Experts Group" and JPG is simply a shortened version of the file extension. Both refer to the same image format.

Some images, especially those with complex details or large dimensions, may not compress to very small sizes while maintaining quality. Try adjusting the quality slider, or consider resizing the image first. For very small targets (like 50KB), you may need to accept lower quality or smaller dimensions.

Make sure your image is in a supported format (JPG, PNG, or WebP) and under the size limit (10MB for single tools, 5MB for batch). Also, check that your browser is up to date and you have a stable internet connection (though the tools work offline once loaded).

Our tools work best on modern browsers like Chrome, Firefox, Safari, and Edge. Make sure your browser is updated to the latest version. Also, check that JavaScript is enabled. If issues persist, try clearing your browser cache or using a different browser.
