What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Why Choose Our Converter?

Accurate, fast conversion from PCD (Kodak Photo CD) to PGM for photography and legacy image workflows

Fast Legacy Image Decode

Efficiently decode Kodak PCD images into raw PGM pixels for quick inspection or batch processing.

Native Grayscale Output

Produce clean PGM grayscale files derived from PCD's RGB or YCC channels with minimal resampling.

Batch Conversion Ready

Process large directories of PCD frames into PGM in grouped jobs to streamline archival workflows.

Wide Toolchain Friendly

PGM outputs integrate with scientific, printing, and image-processing tools that accept Netpbm formats.

Simple Technical Controls

Adjust bit-depth target and optional luminance conversion to tune output for analysis or print prep.

Client-Side Processing Option

ConvertXLab can offer local, in-browser processing to avoid uploading sensitive archival images when possible.

Source vs Target Format

Key technical differences between formats

Feature	Source Format	Target Format
Compression	Kodak proprietary packing	Uncompressed or binary PGM
File Size	Compact on-disc archives	Typically larger raw raster
Quality	Color-rich Kodak scans	Grayscale luminance, lossless
Transparency	No standard alpha, possible masks	Not supported (flattened)
Metadata	Proprietary tags and indexing	No EXIF container in PGM
Primary Use	Photographic archiving and previews	Processing pipelines, analysis, printing

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your PCD files or disc image; choose specific resolution level if present.

Adjust Settings

Pick grayscale method (luminance from RGB or YCC), and choose 8- or 16-bit PGM output.

Convert

Run conversion; decoder extracts pixels from PCD and writes PGM without embedding EXIF or ICC.

Download Result

Save single PGM files or a ZIP bundle; separately download metadata exports if needed.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare PCD Source Scans

Select highest PCD resolution layer before decoding to avoid upscaling artifacts
Identify whether PCD stores YCC; choose matching luminance conversion for best tonal fidelity
If PCD index contains multiple images, extract each to its own PGM file to preserve sequence order
Verify PCD disc image integrity to prevent corrupted pixel blocks in exported PGM
Document original PCD filenames and timestamps since PGM will not carry PCD index metadata

Target PGM Encoding Choices

Choose 16-bit PGM when source exposes full precision and downstream tools accept it
Prefer binary P5 PGM for compactness within Netpbm consumers instead of ASCII P2
Output 8-bit PGM when storage is constrained or target printers require 8-bit channels
If retaining color is essential, convert PCD to TIFF instead and avoid PGM for color workflows
Compress resulting PGMs into ZIP archives to mitigate file-size expansion from PCD

Workflow Integration

Use ImageMagick or Netpbm tools to batch-verify histograms of PGMs post-conversion
Script automated extraction: map PCD indices to output PGM filenames for traceability
Convert representative PCD samples first to tune luminance formula before full batches
Chain conversion: PCD -> PGM -> TIFF if you need later color restoration in editors
Integrate metadata export tasks to accompany PGMs so camera and capture details remain accessible

Verification and Performance

Compare pixel histograms pre- and post-conversion to detect clipping or gamma shifts
Process batches in groups of 20–50 PCDs to balance memory use and CPU throughput
Keep originals locally until you confirm visual and statistical fidelity of PGMs
When using in-browser conversion, close heavy tabs to ensure reliable memory for large PCDs
Validate a few critical images at 100% zoom to ensure no decoding artifacts were introduced

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
