Frequently Asked Questions

Which is the best image converter?

The best converter balances format support with privacy. Our tool excels by offering universal support (JPG, PNG, WebP, BMP, GIF, ICO) without server uploads. Use WebP for website speed optimization, PNG for transparent graphics, and JPG for high-quality photography.

Is it safe to use an online image converter?

Yes, but only if it uses client-side processing like this tool. Because we process your images inside your web browser using HTML5 technology, your files are never uploaded to a remote server. This guarantees absolute data privacy and eliminates the risk of data breaches.

How to convert images to high quality?

Quality depends on your source file and settings. Always start with a high-resolution original. When converting to JPG or WebP, use our quality slider (set to 90% or higher) to minimize compression artifacts. For maximum fidelity, choose lossless formats like PNG or BMP.

How do I export an image without losing quality?

To ensure zero quality loss, select a "lossless" output format such as PNG or BMP. If you must use a compressed format like JPG, ensure the quality slider is set to 100%. Note that converting a low-quality image to a high-quality format will not improve the original resolution.

Is a JPEG or PNG better?

It depends on the content. Choose JPEG for photographs, real-world scenes, and complex gradients to save disk space. Choose PNG for screenshots, logos, images with text, or whenever you require a transparent background.
