Use the browser tools first
Every tool on this site runs entirely inside your browser. We cannot process images sent via email, chat, or any other channel. If you need to convert, compress, resize, crop, or rotate an image, the correct workflow is to open the tool page, load the file, adjust the settings, and download the result. Email is only for feedback, bug reports, and partnership questions. Sending image attachments to our support address will not result in processed files, and large attachments may be blocked by our mail provider.
Check the guides
Most format and compression questions are already answered in the guides section. If you are unsure which format to choose, how to balance quality against file size, or why an exported image looks different from the original, the relevant guide likely covers it. Reading the guide first often resolves the question faster than waiting for an email reply, and it gives you the background to make better decisions next time.
Describe your environment
When reporting a bug, include the browser name and version, your operating system, the exact tool name, and the steps that led to the problem. For example, "Chrome 126 on Windows 11, WebP to PNG converter, the download button does nothing after loading a 4 MB image" is far more useful than "it does not work." Specific details let us reproduce the issue quickly and ship a fix or workaround without a long back-and-forth.
