Why Garmin screenshots are BMP files
Understand BMP source files and why PNG or JPG is usually better for publishing.
Local converter
Upload Garmin .BMP screenshots and export smaller JPG or JPEG files locally in your browser. Files stay on this device. Need PNG instead?
No upload. No account required.
Browser converter
Use this browser tool for quick Garmin BMP to JPG conversion. It also supports the bmp to png Garmin search intent: a real Garmin .BMP screenshot goes in, and a clean JPG file comes out locally in the browser.
Use JiaKe.app for macOS when the screenshot needs the full publishing workflow: importing Garmin screenshots, applying device frames, previewing layouts, and exporting finished assets.
Format choice
JPG is useful for lightweight sharing, but it is lossy. For Garmin screenshots with small numbers, icons, and UI text, PNG remains the better publishing format. Use JPG when size matters more than perfect pixel detail.
Garmin workflow
Garmin screenshots often need context after conversion: a device frame, consistent canvas size, background, padding, export preset, and a repeatable way to prepare multiple app screenshots.
That is why this page connects generic BMP conversion terms with the Garmin-specific JiaKe.app workflow.

FAQ
Yes. Garmin BMP screenshots can be exported as JPG or JPEG directly on this page, with an adjustable quality slider.
Use PNG for Connect IQ Store assets when possible. JPG is better for quick previews and smaller files, but it can blur small text or icons.
JPG does not support transparency. When a BMP image needs a JPG output, transparent or empty areas should be flattened onto a solid background.
