Frequently Asked Questions

What image formats can I transform between?

Our WebAssembly-powered tool supports JPG/JPEG, PNG, WebP, AVIF, BMP, TIFF, ICO, and more. You can transform from any supported format to any other supported format instantly -no server upload required.

Is there a file size limit for processing?

Since all processing happens locally in your browser using WebAssembly, the only limit is your device's available memory. Most modern devices can easily handle images up to 50MB or more.No account limits or processing queues.

Will transforming my image reduce its quality?

It depends on the formats. Transforming between lossless formats (like PNG to BMP) preserves quality perfectly. Converting to lossy formats (like JPG) may reduce quality slightly, but our advanced algorithms optimize for the best possible output quality.

Can I process multiple images at once?

Yes! Our bulk processing feature allows you to transform multiple images simultaneously. Just select all the images you want to process, choose your output format, and handle them all at once.No limits on batch size.

Why should I use WebP or AVIF formats?

WebP and AVIF are modern image formats that offer superior compression compared to traditional formats. They can reduce file sizes by 25-50% while maintaining the same visual quality, making your websites load faster and improving Core Web Vitals scores.
