How to Resize Images for Email
Upload your image
Drag and drop or click to select an image from your computer. JPG format is recommended for email photos, while PNG works better for logos and graphics with text.
Choose a preset or custom size
Select from our email-specific presets: Header (600×200), Banner (600×150), Inline (480×320), or Thumbnail (150×150). Email content should never exceed 600px width for reliable display.
Resize and preview
Click Resize and see your image at the target dimensions. The preview shows exactly how it will appear in your email template.
Download
Download the resized image. For optimal email delivery, compress the resized image using our Image Compressor to keep file sizes under 100KB per image.
Why Email Image Size Matters
Email image sizing is critical for deliverability and user experience. Images wider than 600px may be clipped or scaled down by email clients, leading to broken layouts and slow load times. Different email clients (Gmail, Outlook, Apple Mail, Yahoo) render images differently, so using standardized dimensions ensures consistent appearance across platforms. Large images also increase email file size, which can trigger spam filters or delay loading. By resizing your images to appropriate email dimensions before sending, you ensure fast loading, consistent rendering, and better engagement from your recipients.
