Frequently Asked Questions
Are my images really 100% private?
Yes. ImgZero processes all images using browser HTML5 Canvas and Web Workers. No image bytes, thumbnails, filenames, or metadata are ever uploaded to any server.
Is there any file size limit or daily conversion quota?
No. Since conversion runs locally on your machine, there are no artificial limits or account requirements. Processing speed depends entirely on your device capabilities.
What output image formats are supported?
You can convert between JPG/JPEG, PNG, WebP, and multi-resolution ICO favicons. Additional WebAssembly-based codecs (such as AVIF) load lazily on demand.
Can I convert multiple images at once?
Yes! Drag and drop a batch of images into the Universal Converter or Batch Tools. ImgZero queues jobs safely without memory spikes.
