Export and Save

Downloading your card

HEU-keep provides three download methods:

Save HD Image (recommended)

The main green button. Uses html2canvas to render the preview card at your chosen width and downloads it as a PNG. The file is named "keep[Month][Day]Running.png".

Preview

Opens the rendered card in a new browser tab at full resolution. From there you can right-click and select "Save Image As". Useful as a fallback if the direct download is blocked by your browser.

Backup

An alternative download method using Object URLs. Try this if the other two methods do not work.

Configuring export width

The Width field under Output Size controls the exported image width in pixels. The height is calculated automatically to maintain the correct Keep card aspect ratio (1080:2157). Leave the width field empty to use the default preview size.

Saving your configuration

Click Save Config at the bottom of the control panel to persist your settings to the browser's IndexedDB storage. This saves:

Username and workout title
Distance and pace ranges
Background and track style selections
Color change settings
Export width
Your uploaded portrait photo
Your uploaded custom background image

When you reopen the page, all saved settings are restored automatically. The save is tied to your browser — switching browsers or clearing site data will lose the saved configuration.

Resetting

Click Reset to clear all saved data from IndexedDB. The page returns to its default state.

Note on browser storage

The page requests persistent storage from the browser. This means your data is less likely to be automatically cleared when the browser is under storage pressure. However, manually clearing browser data or using private/incognito mode will still remove everything.
