What Formats Are Supported?

NioTools Image Converter supports all the popular formats in the industry. It instantly converts the HEIC (HEIF) format—which is the default on Apple devices (iPhone/iPad) and often cannot be opened on Windows computers—into standard JPG or PNG formats. You can also perform two-way conversions into the WEBP format, which offers next-generation speed optimization for modern websites.

When Should You Use It? (Use Cases)

  • Transferring iPhone Photos to PC: Convert Apple photos with the .heic extension that you cannot open on your Windows PC into a universal JPG file with a single click.
  • Website Optimization (SEO): Convert your heavy PNG or JPG files to Google's recommended WEBP format to make your site load faster (PageSpeed).
  • Transparent Backgrounds (Logos/Icons): Transfer your design files with white backgrounds into the PNG format that supports an alpha channel for use on your website.
  • Official Forms and Government Uploads: Instantly adapt your document photos to the strictly required JPG format for official institutions that do not accept other extensions.

Frequently Asked Questions

Can I convert iPhone (HEIC) photos? ▾

Yes, HEIC photos from Apple devices are fully supported. They are converted directly to the universal JPG format locally on your device without being sent to a server.

How is my privacy protected during conversion? ▾

NioTools works 100% 'Client-Side'. Your photos never leave your device, and they are never uploaded to or saved on any remote server or database.

Will the image quality drop during conversion? ▾

No, our tool performs high-quality lossless conversion, preserving the original resolution and quality of your images.

If I convert my PNG to JPG, what color will the background be? ▾

Since the standard JPG format does not support transparency (Alpha channel), the transparent areas will automatically be filled with a solid white (#FFFFFF) background when saved.

Is there a file size limit or daily usage quota? ▾

No, because the entire process happens directly in your device's RAM, there are no premium fees, hourly quotas, or file size limits.

Will the converter work if my internet connection drops? ▾

Yes! Once our website has loaded in your browser, the conversion will successfully complete even if your internet connection suddenly drops, because the files are not sent to a remote server.
