Frequently Asked Questions

Is K-Img Converter really 100% free?

Yes! K-Img is a completely free online image converter. We do not require registration, credit cards, or email sign-ups. You can convert unlimited images without any hidden costs.

Is it safe? Do you store my photos?

Your privacy is our top priority. Unlike other converters, K-Img processes images locally in your browser. Your files are never uploaded to a server, ensuring 100% data privacy and security.

Can I convert multiple photos at once?

Currently, K-Img Converter is optimized for high-precision, single-image conversion to ensure the highest quality. However, we are working on a Batch Conversion update that will allow you to upload multiple photos and download them all as a single ZIP file. Stay tuned!

Can I convert iPhone HEIC photos to JPG?

Absolutely. K-Img specializes in converting Apple's HEIC format to JPG or PNG instantly. This makes your iPhone photos compatible with Windows, Android, and all web browsers.

Why should I convert images to WEBP?

WEBP is a modern image format recommended by Google. It reduces file size by up to 35% compared to JPG/PNG without losing quality. Using WEBP improves your website's loading speed and Core Web Vitals score.

Will converting my image reduce its quality?

K-Img uses advanced compression algorithms to balance size and quality. You can control the output using our Quality Slider. For maximum quality, select PNG (Lossless) or keep the JPG quality above 90%.

Does this work on Mobile (Android & iOS)?

Yes, K-Img is fully responsive and optimized for mobile devices. You can convert images directly from your gallery on any Android phone, iPhone, iPad, or Tablet without installing an app.

What is the difference between JPG and PNG?

JPG is best for photographs and realistic images with many colors. PNG is best for graphics, logos, and images requiring transparent backgrounds. Use K-Img to switch between them easily.

Why is K-Img faster than other tools?

Because we use Client-Side Processing. Traditional tools upload your file to a server (slow) then download it back. We convert the file instantly on your device, saving you time and data.

Is there a file size limit?

Since processing happens on your device, we support much larger files than standard converters. However, performance depends on your device's available RAM. Files under 50MB process almost instantly.

Can I use converted images for commercial projects?

Yes. You retain full copyright and ownership of your images. K-Img claims no rights over your files, making it safe for professional photographers, designers, and business use.

In the modern web landscape, page speed and image SEO are critical for ranking on top of search engines. K-Img Converter provides a professional-grade, browser-based solution to optimize your visual content without compromising on quality.
