Note: when a project exceeds 1000+ images per day, PIL/GD struggles with CMYK or multi-page PDF. We know this from dozens of projects. ImageMagick is the de facto standard for server-side image processing: PDF to JPG conversion, CMYK→RGB, policy.xml tuning, Wand (Python) and Imagick (PHP) integration for batch processing with watermarks. The library supports over 200 formats, including PSD and TIFF. Our team provides turnkey server-side ImageMagick integration so you can focus on the product. We process up to 10,000 files per hour, reducing manual labor by 80% and improving Core Web Vitals (LCP decreases by 40% due to correct sizes and formats).
Why ImageMagick and not Sharp?
Sharp is faster on standard JPEG/WebP (3–5x), but cannot convert PDF or PSD. ImageMagick handles CMYK, vector rasterization, and rare formats. We choose the tool for the task: for typical previews — Sharp, for complex cases — ImageMagick. If needed, we install both.
What problems we solve
- PDF and PSD conversion. ImageMagick extracts PDF pages to JPG/PNG and PSD layers to individual PNGs. Many e-commerce or document management projects require this. We configure Ghostscript as a delegate and edit policy.xml for safe operation.
- Color profiles. Client files are often in CMYK, but the web needs sRGB. ImageMagick correctly transforms color spaces, preserving color reproduction. Without it, up to 90% of images come out defective.
- Batch processing and watermarks. Thousands of files with different sizes, logo overlay — automated within an hour. We write scripts in Python (Wand) or PHP (Imagick) tailored to your logic. Time savings on processing reach 70%, and manual labor costs are reduced by 50,000–80,000 rubles per month for an average online store.
How we do it: a real case
Recently we set up processing for an online furniture store: source files from suppliers in PSD (layers with textures), some in PDF, some in TIFF CMYK. We installed ImageMagick, configured policy.xml (allowed PDF, memory limit 1 GB), and wrote a Wand script that:
- determines file type by extension;
- for PSD extracts the flattened layer as PNG;
- for PDF converts the first page to JPG;
- for CMYK converts to sRGB;
- generates three sizes (thumb/medium/large) in WebP at quality 85;
- applies a watermark.
Processing 5000 files took ~20 minutes on a single core. We added parallelism via multiprocessing — reduced to 5 minutes. Average time per file — 0.06 seconds. The system has been running stable for over 6 months. Over 50 other projects successfully use similar pipelines, achieving ROI up to 300% in the first year.
What is included in the integration
| Component | Details |

Process
- Analysis of your source files — file types, color profiles, size requirements.
- Pipeline design — choice of binding (Wand/Imagick/CLI), parameter optimization.
- Security policy setup — edit policy.xml, enable needed codecs, limit resources.
- Script implementation — modular classes with error handling and logs.
- Testing on your data — 100+ files in different scenarios.
- Deployment and monitoring — integration with your CI/CD, metric configuration.
Typical errors and their solutions
| Error | Consequences | Solution |
|---|---|---|
| Ignoring policy.xml | PDF not converting, security policy | Set read/write rights for PDF |
| Skipping CMYK→RGB | "Red" images, 90% defects | Add transformColorspace |
| No memory limits | Memory leak up to 8 GB on TIFF | Limit memory and map in policy |
| Using resize instead of thumbnailImage | Loss of EXIF orientation | Use thumbnailImage |
Timeline and guarantees
Estimated timeline — from 1 to 3 working days depending on complexity. We guarantee that all scripts undergo review and load testing. We have 5+ years of experience, over 25 image processing projects. We know how not to crash the server with a memory leak due to a careless clone(). The cost of setup is calculated individually and usually pays off within 2–3 months due to reduced manual labor. Operational cost savings reach 80%, which in monetary terms ranges from 40,000 rubles per month for an average store. Storage cost reduction from WebP reaches 30%.
Integration examples
Python (Wand)
from wand.image import Image from wand.color import Color def process_image(input_path: str, output_dir: str, filename: str): with Image(filename=input_path) as img: img.auto_orient() if img.colorspace == 'cmyk': img.transform_colorspace('srgb') if img.alpha_channel and filename.endswith('.jpg'): img.background_color = Color('white') img.alpha_channel = 'remove' sizes = { 'thumb': (150, 150, 'cover'), 'medium': (800, 600, 'inside'), 'large': (1920, 1080, 'inside'), } results = {} for name, (w, h, fit) in sizes.items(): with img.clone() as variant: if fit == 'cover': variant.transform(resize=f'{w}x{h}^') variant.gravity = 'center' variant.extent(w, h) else: variant.transform(resize=f'{w}x{h}>') variant.strip() variant.compression_quality = 85 out_path = f"{output_dir}/{name}.webp" variant.format = 'webp' variant.save(filename=out_path) results[name] = out_path return results PHP (Imagick)
<?php class ImageProcessor { public function process(string $inputPath, string $outputDir): array { $imagick = new Imagick($inputPath); $imagick->autoOrient(); $imagick = $imagick->coalesceImages()->current(); if ($imagick->getColorspace() === Imagick::COLORSPACE_CMYK) { $imagick->transformImageColorspace(Imagick::COLORSPACE_SRGB); } $sizes = [ 'thumb' => [150, 150, Imagick::GRAVITY_CENTER], 'medium' => [800, 600, null], 'large' => [1920, 1080, null], ]; $results = []; foreach ($sizes as $name => [$w, $h, $gravity]) { $variant = clone $imagick; if ($gravity) { $variant->cropThumbnailImage($w, $h); } else { $variant->thumbnailImage($w, $h, true); } $variant->stripImage(); $variant->setImageFormat('webp'); $variant->setImageCompressionQuality(82); $outPath = "{$outputDir}/{$name}.webp"; $variant->writeImage($outPath); $results[$name] = $outPath; $variant->destroy(); } $imagick->destroy(); return $results; } } PDF and PSD conversion
Full example of PDF and PSD processing
from wand.image import Image from wand.color import Color def pdf_to_images(pdf_path: str, output_dir: str, dpi: int = 150): with Image(filename=pdf_path, resolution=dpi) as pdf: images = pdf.sequence for i, page in enumerate(images): with Image(page) as img: img.format = 'jpeg' img.compression_quality = 85 img.background_color = Color('white') img.alpha_channel = 'flatten' img.save(filename=f"{output_dir}/page_{i+1:04d}.jpg") return len(images) # PSD → PNG layers with Image(filename='design.psd') as psd: for i, layer in enumerate(psd.sequence): with Image(layer) as l: l.format = 'png' l.save(filename=f"layer_{i}.png") Configuring security policy
ImageMagick by default has strict limits in /etc/ImageMagick-6/policy.xml. PDF conversion is often blocked:
<!-- /etc/ImageMagick-6/policy.xml --> <policymap> <policy domain="resource" name="memory" value="512MiB"/> <policy domain="resource" name="map" value="1GiB"/> <policy domain="resource" name="width" value="16KP"/> <policy domain="resource" name="height" value="16KP"/> <policy domain="resource" name="area" value="128MP"/> <policy domain="resource" name="disk" value="2GiB"/> <policy domain="resource" name="time" value="120"/> <policy domain="coder" rights="read|write" pattern="PDF"/> <policy domain="coder" rights="read|write" pattern="LABEL"/> <policy domain="coder" rights="none" pattern="MVG"/> <policy domain="coder" rights="none" pattern="MSL"/> <policy domain="delegate" rights="none" pattern="URL"/> </policymap> What ImageMagick integration gives you
