Frequently Asked Questions
Will converting from image files to ICO icon format reduce quality?
Conversion preserves the original content as closely as the target format allows. Some format-specific features may render differently since formats have different capabilities.
Is there a file size limit?
Free online converters typically have a reasonable per-file size limit to keep processing fast. Very large files may need to be split or compressed first.
Are my uploaded files stored?
Files are processed for conversion and are not intended for long-term storage — download your result promptly after conversion.
