Frequently Asked Questions

What is an image converter?

An image converter is a tool that changes an image from one format to another (e.g., PNG to JPG). This helps make images compatible with different websites, applications, or devices.

Is this image converter free?

Yes! Our image converter is completely free. No registration, no hidden costs, no limits. You can convert as many images as you need.

What image formats are supported?

We support conversion between JPG, JPEG, PNG, WEBP, BMP, and GIF formats. You can convert any of these formats to any other supported format.

Can I resize images while converting?

Absolutely! Our tool includes a resize feature that lets you specify custom width and height. You can resize proportionally or set exact dimensions.

Does JPG conversion reduce quality?

JPG uses lossy compression, so there is some quality reduction. However, you can adjust the quality level (from 10% to 100%) to balance file size and image quality. For most web use, 85% quality provides excellent results.

Is my image data secure?

Yes! All conversion happens directly in your browser. Your images never leave your computer - we don't upload anything to any server. This makes our tool 100% private and secure.

What's the difference between PNG and JPG?

PNG is lossless and supports transparency, making it ideal for logos, graphics, and images with text. JPG/JPEG uses lossy compression for smaller file sizes, making it better for photographs and web images where file size matters.

What is WEBP format?

WEBP is a modern image format developed by Google that provides superior compression for web images. It typically produces files 25-35% smaller than JPG at similar quality, and supports both lossy and lossless compression with transparency.
