About formats

PSD (Photoshop Document) is the native file format of Adobe Photoshop, the industry-standard raster image editor first released on February 19, 1990. PSD files preserve the complete editing state of a Photoshop project: all layers (raster, text, adjustment, shape, and smart object layers) with their positions, blending modes, opacity, and layer effects; layer masks and vector masks; alpha channels; spot color channels; paths; guides; slices; and the full undo history. The format supports images up to 30,000 x 30,000 pixels (PSB, the large document format, extends this to 300,000 x 300,000) in color modes including RGB, CMYK, Lab, Grayscale, Indexed, Duotone, and Multichannel, at 1, 8, 16, or 32 bits per channel. PSD files use a combination of RLE compression for individual layer data and store composite (flattened) preview images for quick display by applications that cannot parse the full layer structure. The format has become a de facto standard for professional creative workflows far beyond Photoshop itself — photographers, graphic designers, web developers, and video post-production artists exchange PSD files as the working format that preserves creative flexibility. One advantage is the non-destructive editing model: PSD preserves every layer, mask, adjustment, and effect as independently editable elements, allowing creative decisions to be revised at any point without starting over. The format's role as the interchange standard for the creative industry provides another core strength — PSD files can be opened by Adobe Illustrator, InDesign, After Effects, Premiere Pro, as well as Affinity Photo, GIMP, Sketch, Figma, and Photopea, making it the lingua franca of visual design.

JBG is a file extension for images compressed using the JBIG (Joint Bi-level Image experts Group) standard, formally ITU-T Recommendation T.82, completed in 1993 as a successor to the Group 3 and Group 4 fax compression standards. JBIG compression is designed for bi-level (black and white) images but can also handle grayscale and limited-color images by encoding each bit plane separately. The algorithm uses a form of arithmetic coding guided by an adaptive context model: for each pixel, the encoder examines a template of surrounding already-coded pixels to build a probability estimate, then feeds this estimate to a QM-coder (a variant of the Q-coder arithmetic coder) that produces a highly efficient binary output. JBIG achieves 20-40% better compression than Group 4 on typical document images, with the improvement being even larger on halftoned photographs and images with gradual density transitions where Group 4's simple run-length approach is less effective. The standard supports progressive encoding, where a low-resolution version of the image is transmitted first and progressively refined — useful for fax-like applications where the receiver can begin displaying the image before the full-resolution data arrives. One advantage is superior compression of documents containing halftone images: newspapers, magazines, and marketing materials that mix text with photographic halftones compress dramatically better with JBIG than with Group 3/4. The standard's ITU-T backing ensures it is implemented in document imaging hardware and software worldwide. JBG files are supported by ImageMagick and various document imaging tools.

Frequently Asked Questions

Why convert PSD to JBG?

JBG is useful when you need your Photoshop design in a specific format for specialized tools, legacy systems, or particular workflows.

What opens JBG files?

document imaging and fax systems handle the JBG format for viewing and processing.

Does conversion flatten PSD layers?

Yes — JBG is a flat format. All Photoshop layers merge into a single image during the conversion process.

Is the output quality good?

Your PSD artwork is rendered at high quality before encoding into the JBG format for maximum fidelity.

Is PSD to JBG conversion free?

Standard conversions are free on Convertio. Premium plans offer batch processing and faster speeds.
