Privacy — ConvertFern

Image processing happens in your browser

The five converters read selected files into temporary browser memory. JavaScript and the bundled HEIC decoder process the images locally. Original and converted image contents are not uploaded to a server, conversion API, third-party storage or database. The conversion pages block script-based network connections through a Content Security Policy. Site assets still need to be downloaded when you load a page or tool.

Temporary memory and cleanup

Images, PDFs and ZIP archives remain in this tab’s memory while you use them. We do not write image contents to cookies, local storage, IndexedDB or other persistent browser storage. Processing workers are terminated after a batch or cancellation. Clearing or replacing results releases application references; retired download URLs have a short grace period of up to two minutes so an in-progress download is not interrupted. Browser memory cleanup is managed by the browser. Closing the tab ends this temporary workspace.

Downloads stay on your device

Download buttons save locally generated results through your browser. A blob: address identifies temporary browser data, not a server upload. Original files and downloads already saved to your device are not deleted by Clear all or closing the tab.

Contact messages

When you submit our contact form, we process the name, email address, subject and message you enter to respond to your enquiry. The form sends the message from our website server to our Hostinger email service over an encrypted SMTP connection, where it may be retained in the contact mailbox until deleted. If you contact us using your own email app, your email provider and ours also process the information you send. We do not accept image attachments through the form. Please avoid sending passwords, private images or other sensitive information.

To prevent automated abuse, our form uses a hidden anti-spam field and temporarily stores a pseudonymous value derived from the request IP address for rate limiting, normally for up to 15 minutes; normal hosting and email-provider logs may be retained separately under their own policies. Contact-form information is separate from image conversion: images selected in our converters remain in your browser and are not attached to contact messages.

Hosting, analytics and advertising

The host receives ordinary website requests and may log IP addresses, browser information, paths and timestamps. Those requests do not include files selected in the converters. This site currently includes no analytics or advertising scripts and no conversion database. If analytics or advertising is added later, the relevant data handling and consent controls must be documented before it is activated.
