Frequently asked questions
What is AnyToolsKit?
AnyToolsKit is a free collection of browser-based file tools. Right now it includes ICO and favicon tools (icon editor, image to ICO, favicon generator, ICO viewer) and PDF tools (PDF to JPG, PNG and WebP). More sections will follow.
Are my files uploaded anywhere?
No. All processing happens in your browser on your own device. The website only delivers the tool code; your files are never sent to a server.
Is it really free?
Yes. There are no accounts, limits or watermarks. The site is funded by advertising.
Does it work on phones?
Yes. All tools work in modern mobile browsers. Very large PDFs or high DPI settings need more memory, so phones automatically use a lower safety limit.
Which languages are supported?
Every page and guide is available in English and Korean. Use the language switch in the header.
