Common Image Resizing Needs

📸 Resize Image for Passport Photo

Need to resize images for passport photos? Standard passport photo sizes are 2x2 inches (600x600 pixels) for US passports. Simply upload your photo, select "By Pixels" mode, and enter 600x600 with aspect ratio maintained. Download your passport-ready photo instantly.

📱 Resize Image for Instagram

Instagram has specific image dimensions for best results. Feed posts: 1080x1080px (square), 1080x1350px (portrait), or 1080x608px (landscape). Stories: 1080x1920px. Use our tool to resize images to these exact dimensions for optimal Instagram display.

📧 Resize Image for Email Attachment

Email attachments typically have size limits (10-25MB). Reduce image dimensions by 50-70% to make them email-friendly. Our percentage slider makes it easy—start at 50% and adjust quality to balance file size and visual clarity.

🌐 Resize Image for Website

Website images should be optimized for fast loading. Header images: 1920x1080px, blog featured images: 1200x630px, thumbnails: 300x300px. Resize to these dimensions and set quality to 80-85% for the best performance.

🎨 Resize Image to Specific Pixels

Need exact dimensions? Common sizes include: Profile pictures (200x200px), thumbnails (150x150px), banners (728x90px), and social media covers. Use "By Pixels" mode to enter exact width and height values for pixel-perfect results.

📐 Resize Image to 300x300

The 300x300px size is perfect for avatars, profile pictures, and product thumbnails. Enable "Maintain aspect ratio" if you want the image to fit within 300x300 without distortion, or disable it for an exact square crop.

How to Resize Images Online (Step-by-Step)

  2. Choose Resize Method: Select "By Percentage" for proportional scaling or "By Pixels" for exact dimensions.
  3. Set Dimensions: Adjust the percentage slider (10-200%) or enter specific width/height in pixels.
