Frequently asked questions

Is Image Converter free?
Yes. Convert images on TheToolss for free with no signup.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser using canvas — files never leave your device.
What happens to transparency when converting to JPEG?
JPEG has no transparency, so transparent areas are filled with the background color you choose before converting.
Which format should I pick?
Use JPEG for photos, PNG when you need transparency or lossless quality, and WebP for the smallest web-friendly files.
Can I convert multiple images at once?
Yes. Upload up to 20 images and download them together as a ZIP.
