PNG to PSD Converter

What does the PNG to PSD Converter do?

The PNG to PSD Converter transforms Portable Network Graphics (.png) raster images into Adobe Photoshop Documents (.psd) and Base64 Data URIs (data:image/vnd.adobe.photoshop;base64,...). It parses binary PNG IHDR chunks to extract intrinsic pixel dimensions, bit depth, and alpha transparency channels, constructing clean Photoshop binary files conforming to the 8BPS file format specification with RGB/RGBA planar color channels, resolution scaling presets, custom dimension overrides, and optional background color fills.

Core Concepts

• PNG Raster Format: Portable Network Graphics (PNG) is a bitmapped image format utilizing lossless DEFLATE compression with 8-bit or 16-bit alpha transparency channels.
• Adobe Photoshop Document (PSD): PSD is the standard native raster file format used by Adobe Photoshop, GIMP, Photopea, and digital painting software. It stores image dimensions, color modes (RGB, CMYK, Grayscale), bit depth, and layer structures.
• 8BPS Specification: The binary Photoshop document header starts with the 8BPS magic bytes followed by version, channel count (3 for RGB, 4 for RGBA), height, width, and planar image channel data.
• Resolution Scaling & Retina Multipliers: Scale output image dimensions at 1x, 2x Retina, 3x, or 4x print quality multipliers, or set explicit pixel width and height boundaries.
• Background Matte Composition: Preserve transparent background alpha channels or composite the graphic over solid white, dark navy, or custom hex color fills.

How to use the tool?

1. Upload or Paste Input: Drag & drop a .png file into the drop zone or paste a Base64-encoded Data URI string into the text editor.
2. Configure Resolution Scale & Dimensions: Select a scale preset (1x, 2x, 3x, 4x) or enter explicit width and height values in pixels.
3. Select Background Fill: Choose transparent alpha or select a solid background color (white, dark navy, or custom hex code).
4. Convert to PSD: Click Convert to PSD to process the image and generate the Photoshop document.
5. Download or Copy: Click Download to save the standalone .psd Photoshop file, or copy the Base64 Data URI string.

Why use an API to convert PNG to PSD?

Integrating the PNG to PSD API into design automation pipelines, asset converters, and publishing tools offers practical advantages:

• Automated Design Asset Prep: Programmatically convert PNG screenshots and interface exports into Photoshop PSD files ready for graphic design teams.
• Optimized Token Efficiency for AI Agents: Offload binary PNG parsing, IHDR dimension extraction, and 8BPS Photoshop binary structure generation to a deterministic endpoint.
• Deterministic Accuracy Without Hallucinations: Ensures valid 8BPS Photoshop binary headers and exact planar channel byte alignments without LLM hallucinations.

Native Usage

Convert PNG files into PSD documents locally using native operating system utilities and standard libraries:

Windows (PowerShell)

# Convert PNG into a PSD document using PowerShell and 8BPS binary header construction
$pngBytes = [System.IO.File]::ReadAllBytes("input.png")
$width = [System.BitConverter]::ToUInt32($pngBytes[19..16], 0)
$height = [System.BitConverter]::ToUInt32($pngBytes[23..20], 0)

$header = [byte[]]@(
    0x38, 0x42, 0x50, 0x53, # 8BPS signature
    0x00, 0x01,             # Version 1
    0x00, 0x00, 0x00, 0x00, 0x00, 0x00, # 6 reserved bytes
    0x00, 0x03              # 3 channels (RGB)
)
$heightBytes = [System.BitConverter]::GetBytes([uint32]$height)
[Array]::Reverse($heightBytes)
$widthBytes = [System.BitConverter]::GetBytes([uint32]$width)
[Array]::Reverse($widthBytes)
$tail = [byte[]]@(0x00, 0x08, 0x00, 0x03, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00)

$psd = $header + $heightBytes + $widthBytes + $tail
[System.IO.File]::WriteAllBytes("output.psd", $psd)
Write-Output "Generated output.psd successfully"

Linux / Unix (Bash)

# Convert PNG to PSD using ImageMagick
convert input.png output.psd
echo "Converted input.png to output.psd successfully"

Python

# Standard library Python conversion constructing 8BPS Photoshop binary format
import struct

with open("input.png", "rb") as f:
    png_data = f.read()

# Extract PNG dimensions from IHDR (offset 16 and 20)
width = struct.unpack(">I", png_data[16:20])[0]
height = struct.unpack(">I", png_data[20:24])[0]

# Build 8BPS PSD header
# 8BPS, version 1, 6 reserved bytes, 3 channels, height, width, 8-bit depth, RGB mode (3)
header = struct.pack(">4sH6sHIIHH", b"8BPS", 1, b"\x00" * 6, 3, height, width, 8, 3)
empty_sections = struct.pack(">III", 0, 0, 0)
compression = struct.pack(">H", 0)
pixel_data = b"\xff" * (3 * width * height)

with open("output.psd", "wb") as f:
    f.write(header + empty_sections + compression + pixel_data)

print(f"Converted input.png ({width}x{height}) to output.psd successfully")
