SVGZ to PSD Converter

The SVGZ format is strictly a GZIP-compressed version of a standard Scalable Vector Graphics (SVG) file. It utilizes the Deflate compression algorithm (RFC 1951) to reduce the file size of the verbose XML text data typically found in standard SVGs, often achieving size reductions of 50-80%. While functionally identical to SVG in terms of graphical rendering capabilities and DOM structure, the binary compression prevents the file from being readable in standard text editors without prior decompression.

Most modern web browsers (Chrome, Firefox, Safari) render SVGZ files natively, provided the web server serves them with the correct Content-Encoding: gzip header. For offline editing, vector graphics tools like Adobe Illustrator and Inkscape automatically handle the decompression and display the graphic. If manual inspection is required, the file can be renamed with a .gz extension and decompressed using utilities like 7-Zip or GNU Gzip.

The Photoshop Document (PSD) is the proprietary file format of Adobe Photoshop, capable of storing an image with support for all available imaging options including layers, adjustment layers, layer masks, alpha channels, paths, and vector text. It utilizes Run-Length Encoding (RLE) for compression and allows for a maximum file size of 2 GB and dimensions up to 30,000 pixels. The format maintains the editing history and non-destructive elements of a project, unlike flattened raster formats. The internal structure is divided into five parts: File Header, Color Mode Data, Image Resources, Layer and Mask Information, and Image Data.

Adobe Photoshop is the primary software for full PSD support. However, several other programs offer varying degrees of compatibility. GIMP (GNU Image Manipulation Program) and Paint.NET (with a plugin) can open PSD files but may not render complex layer styles or adjustment layers correctly. CorelDRAW and Affinity Photo also provide robust support. For simple viewing without editing, standard image viewers like XnView or IrfanView can often display the flattened composite preview embedded within the file.
