FAQ

Frequently Asked Questions

Is this image converter really free?
Yes, our image converter is completely free to use. There are no hidden fees, no registration required, and no limits on the number of conversions.
Are my images uploaded to a server?
No, all conversions happen locally in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
We support all major image formats including JPG, PNG, WebP, GIF, BMP, AVIF, HEIC, TIFF, and SVG. You can convert between any of these formats, including iPhone HEIC photos.
Can I convert multiple images at once?
Yes, you can upload and convert multiple images simultaneously. You can also download all converted images as a single ZIP file.
Will the converted images have watermarks?
No, converted images do not have any watermarks. You get clean, professional-quality output files.
Is there a file size limit?
There is no strict file size limit. However, very large files may take longer to process depending on your device's capabilities.
Can I reduce an image to 2 colors?
Yes. Open Advanced Color & Compression, choose Black & white for a threshold effect, or Reduce colors and set max colors to 2. Dithering helps keep smooth gradients when using few colors.
How do I remove transparency (4 bytes to 3 bytes per pixel)?
Set Pixel format to RGB — no transparency. This removes the alpha channel so each pixel uses 3 bytes instead of 4. JPG output also removes transparency automatically.
What's the difference between quality and color count?
Quality controls lossy compression for JPG, WebP, and AVIF. Color count controls how many distinct colors remain in the image before saving — useful for icons, logos, and black-and-white output.
