How to Batch Convert a Folder of PSD Files to JPEG, PNG, or PDF in .NET

Batch conversion saves hours for designers, developers, and teams managing large PSD archives. Aspose.PSD for .NET makes it simple to convert entire folders of PSD files to JPEG, PNG, or PDF with just a few lines of code.

Real-World Problem

Converting PSD files one by one is tedious and error-prone. Automation lets you process hundreds or thousands of PSDs in seconds.

Solution Overview

Loop over your folder, load each PSD, and export in your desired format. Catch and log errors for full traceability.

Prerequisites

  1. Visual Studio 2019 or later
  2. .NET 6.0 or later (or .NET Framework 4.6.2+)
  3. Aspose.PSD for .NET from NuGet
  4. Input/output folder structure with PSD files
PM> Install-Package Aspose.PSD

Step-by-Step Implementation

Step 1: Prepare Batch Folders and File Pattern 

using Aspose.PSD;
using Aspose.PSD.FileFormats.Psd;
using Aspose.PSD.ImageOptions;

string inputDir = "./input_psd";
string outputDir = "./output_jpeg";
Directory.CreateDirectory(outputDir);

var files = Directory.GetFiles(inputDir, "*.psd");

Step 2: Batch Convert to JPEG 

foreach (var file in files)
{
    try
    {
        using (var image = (PsdImage)Image.Load(file, new PsdLoadOptions() { LoadEffectsResource = true }))
        {
            string outPath = Path.Combine(outputDir, Path.GetFileNameWithoutExtension(file) + ".jpg");
            var jpegOptions = new JpegOptions() { Quality = 85 };
            image.Save(outPath, jpegOptions);
        }
    }
    catch (Exception ex)
    {
        // Log or handle error
        Console.WriteLine($"Failed to convert {file}: {ex.Message}");
    }
}

Step 3: (Optional) Convert to PNG or PDF Instead 

// PNG:
// var pngOptions = new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha };
// image.Save(outPath, pngOptions);

// PDF:
// var pdfOptions = new PdfOptions();
// image.Save(outPath, pdfOptions);

Use Cases and Applications

  • Process large design libraries for web, print, or archive
  • Automate asset production for ecommerce, branding, or digital platforms
  • Convert PSDs to lightweight formats for sharing

Common Challenges and Solutions

Unexpected errors or failed files: Always log issues for review and possible re-processing.

Output folder clutter: Use subfolders per format or project for clarity.

Best Practices

  • Preview sample outputs before large batch jobs
  • Backup originals and use non-destructive scripts
  • Automate for full scalability

FAQ

Q: Can I change the file pattern for PSB, TIFF, or other formats? A: Yes—update your Directory.GetFiles pattern as needed.

Q: How do I add more output formats? A: Use other Aspose.PSD ImageOptions for TIFF, GIF, BMP, etc.
