FAQ

• Q: Does resizing lower the image quality?
  A: Our tool uses advanced bicubic interpolation to maintain the highest possible clarity when downscaling. When upscaling, we preserve edges to minimize blurring.
• Q: What units can I use?
  A: You can resize using pixels (px), percentages (%), or real-world units like inches (in) and centimeters (cm) with customizable DPI settings.
• Q: How does aspect ratio locking work?
  A: When the lock icon is active, changing the width will automatically calculate the height (and vice versa) to prevent any stretching or squashing of the image.
• Q: Are social presets updated?
  A: Yes! We monitor all major social platforms weekly to ensure our presets match the latest recommended upload dimensions for 2025.
• Q: Which formats are supported?
  A: We support JPG, PNG, WEBP, and even GIF (static frame resizing). We prioritize browser-native formats for the fastest processing speeds.
• Q: Is there a file size limit?
  A: Since processing happens on your own computer, we can handle files up to 50MB comfortably. For extremely large files, ensure your device has sufficient RAM.
