A printed flyer often contains more information than a Status viewer can read comfortably. A full address, several logos, long terms, and small contact details may all look clear in a large design window but become tiny on a phone. Decide what the viewer must understand immediately, then simplify the source design before compressing it.
This page exports our 1080×1920 pixel vertical JPEG. A source with another shape will be cropped to fill it, so do not drop a wide flyer into the tool and assume every word will remain. Make a vertical version in your design application if the full layout matters. The compressor does not rearrange text, move logos, or add the empty background needed to preserve a differently shaped poster.
Keep the main message and any necessary action away from the top and bottom boundaries. WhatsApp's interface can occupy parts of the screen, and actual framing should be checked in the app. The export size is a preparation choice, not a guarantee of an unobstructed area. Inspect the Status preview before sharing, especially when a date, location, or price sits near an edge.
