PS to G4 conversion is the process of transforming a file in the PostScript (PS) page description format into a Group 4 (G4) compressed bi-level image format, typically used for fax and monochrome scanned images. This conversion rasterizes the vector/text instructions in PS into a black-and-white bitmap and then applies CCITT Group 4 (G4) lossless compression for efficient storage and transmission.

CSV and XLSX both move spreadsheet data, but they solve different problems. CSV is small, plain text, and ideal for databases, APIs, automation, and clean tabular exchange. XLSX is richer, supporting formulas, multiple sheets, charts, styles, validation, and business-ready workbooks. This guide compares spreadsheet formats, explains conversion workflows, and helps you choose the right format for data sharing, analysis, and long-term use.

PS files use the MIME type application/postscript and are often used in professional printing workflows. G4 files, defined by the TIFF Group 4 Fax standard, use MIME type image/tiff and are optimized for fax transmission. The G4 format employs CCITT Group 4 compression codec, which efficiently compresses monochrome images.
The G4 (.G4) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like PS.
While specific technical details aren't available here, G4 files generally serve the purpose of storing other effectively within their domain.
Our online PS to G4 converter offers a seamless way to convert your PS files to the G4 format without any software installation. Designed for efficiency and ease of use, this tool supports fast conversions while maintaining file quality.
PS files are typically used for print-ready documents with high-quality vector information, while G4 is a compressed format primarily used for faxing and scanned images. G4 offers better compression and smaller file sizes compared to PS, making it ideal for document transmission. However, PS maintains more detailed image and layout information.
Keep raster resolution between 200–300 DPI for documents and 300–400 DPI for small-font or fine-line artwork to preserve legibility while limiting file size.
Preserve quality by embedding fonts in the PS or flattening text to outlines before conversion to avoid substitution and layout shifts.
For photographic or grayscale content, remember G4 is bi-level; convert photos to grayscale or use a different format (e.g., TIFF LZW or JPEG) if you need continuous tones.
Batch convert multiple PS files by consolidating pages into a single multi-page PS or using a tool that supports queueing; monitor memory usage for large batches.

Limitations: G4 is intended for bilevel (black-and-white) images only, so color and grayscale detail will be lost; transparency and complex vector effects are rasterized.
