PHOTOSHOP Document to G3 conversion is the process of exporting or translating a layered PSD (Photoshop Document) into the G3 raster format, commonly used for facsimile and certain legacy imaging workflows. This converts Photoshop pixel and flattened preview data into the G3 compression scheme (often Group 3 fax), producing a monochrome or bilevel raster image suitable for faxing or systems that require CCITT Group 3 encoding.

Drag your .PSD file from your computer or use the browse function.
Confirm .g3 as the selected destination format.
Click "Convert" and download your converted .G3 file once ready.
PSD files use the MIME type image/vnd.adobe.photoshop and store layered raster graphics primarily for editing purposes. G3 files use the MIME type image/g3fax and employ Group 3 fax compression, designed for monochrome image transmission over telephone lines. G3 is widely used in fax machines and document scanning systems that support TIFF or similar wrappers.
The G3 (.G3) format is commonly used for other. Understanding its characteristics can be helpful when converting to or from other formats like PHOTOSHOP Document.
While specific technical details aren't available here, G3 files generally serve the purpose of storing other effectively within their domain.

PHOTOSHOP Document (PSD) files support complex layered images with rich color depth, ideal for detailed graphic design work. In contrast, G3 files are optimized for monochrome images, commonly used in fax transmissions and simple document storage. While PSD offers extensive editing capabilities, G3 focuses on efficient compression and wide device compatibility for scanned images.
Keep final file sizes small: G3 is a bilevel/compressed format—reduce color layers and flatten PSDs before conversion to minimize size.
Preserve clarity: convert to grayscale and apply appropriate dithering (Floyd–Steinberg for photos, thresholding for line art) to retain detail when moving from continuous-tone PSD to bilevel G3.
Batch conversion: process multiple PSD files by automating flattening, resizing to target dpi (200–300 dpi), and applying consistent threshold/dither settings to ensure uniform output.
Limitations: G3 is a bilevel (black-and-white) compression standard—color, alpha channels, and layer information are lost during conversion.
This converter made switching from PSD to G3 incredibly simple and fast.

Optimal sizes: for best balance between quality and compatibility, export at 200–300 dpi and under 1 MB for typical single-page fax-ready images; very large PSDs may need downscaling or conversion to TIFF+G3.
