Frequently asked questions

How do I convert with Image to ICO?
Select one or more image files, wait for the conversion preview, then download the output. Conversion happens locally in your browser.
What is the difference between this and the Favicon Generator?
This tool downloads a single .ico file. The Favicon Generator creates a full ZIP kit with PNGs, manifest, and multiple web assets.
Which ICO sizes should I use?
The standard 16, 32, and 48 px preset works for most Windows and browser favicon use cases.
Are my images uploaded to your servers?
No. Image tools run entirely in your browser. Your photos stay on your device and are not sent to our servers for processing.
Do I need an account or subscription?
No account is required. Online Tool Hub image tools are free to use with no signup and no usage limits.
