How to Strip EXIF Metadata & Geolocation Coordinates from Photos

export async function sanitizeImagePixels(file: File, quality = 0.92): Promise<Blob> {
  return new Promise((resolve, reject) => {
    const img = new Image();
    img.onload = () => {
      const canvas = document.createElement('canvas');
      canvas.width = img.naturalWidth;
      canvas.height = img.naturalHeight;
      const ctx = canvas.getContext('2d');
      if (!ctx) return reject(new Error('Canvas context unavailable'));

      // Draw purely raw RGBA pixels - discards all EXIF / GPS APP1 blocks
      ctx.drawImage(img, 0, 0);

      // Re-encode sanitized pixels into a clean WebP/JPEG blob
      canvas.toBlob((blob) => {
        if (blob) resolve(blob);
        else reject(new Error('Blob conversion failed'));
      }, 'image/webp', quality);
    };
    img.src = URL.createObjectURL(file);
  });
