Important note
Instagram may still apply its own compression after upload. This tool prepares images in Instagram-friendly dimensions, but final display can vary based on Instagram app behavior, account settings, device and upload quality.
Your original image remains unchanged. Always review the preview before posting, especially when using cover mode because it may crop edges to fill the selected frame.
