| File extension | .PLT |
| Category | CAD File |
| Description | Actually, it is not a format, as some people think. PLT (HPLG, Hewlett Packard Graphics Language) is the standard extension, which programs use while printing 2D graphics, particularly line drawings. Associated with AutoCAD, PLT files comprise vector graphic plotter files, which are also supported by OziExplorer, HP Graphics Language and Bentley’s CAD MicroStation. In order to print a PLT files, you should use a plotter, which uses linear drawing method instead of dotting images. |

| Description | The TIFF (Tagged Image File Format) is a widely-used file format for storing digital images, developed by Aldus Corporation (now owned by Adobe Systems). It is a versatile format that supports a wide range of color depths, resolutions, and image types, making it suitable for use in a variety of applications. TIFF files can contain multiple images, each with their own characteristics such as resolution, compression, and color depth. They can also be uncompressed or compressed using a variety of methods, such as LZW, ZIP, and JPEG compression. Additionally, TIFF files can store metadata such as keywords, descriptions, and copyright information. One of the key benefits of the TIFF format is its support for high-quality, lossless image compression. This makes it a popular choice for archiving and sharing images, especially in fields such as graphic design, printing, and photography. TIFF files can also support transparent backgrounds, making them ideal for use in web graphics and other applications where transparency is important. TIFF files can be opened and edited using a wide variety of software programs, including Adobe Photoshop, GIMP, and Microsoft Paint. They are also supported by many operating systems and web browsers. Overall, the TIFF format is a robust and versatile format for storing digital images. Its ability to support multiple images, high-quality compression, and metadata make it a popular choice for a variety of applications, especially those requiring high-quality images. |

PLT files contain HPGL vector drawing commands intended for pen plotters — they are not images you can open in standard photo or document software. Converting PLT to TIFF gives you a high-resolution raster image that any printer, publishing workflow, or archival system can handle without a plotter driver. Drop your .plt file above.
PLT is a plotter file format based on Hewlett-Packard's HPGL (HP Graphics Language). It describes drawings as a sequence of pen-move commands — lines, arcs, and fills — rather than pixel data. CAD applications such as AutoCAD, CorelDRAW, and various GIS tools export PLT for plotters. Outside of that ecosystem, virtually no standard viewer or printer understands the format directly.
TIFF (Tagged Image File Format) is a lossless raster format developed by Aldus and now maintained by Adobe. It supports any bit depth, multiple color spaces (RGB, CMYK, grayscale), optional compression, and multi-page storage. Print shops, scanners, and archival systems treat TIFF as their standard interchange format because it preserves every pixel without quality loss.
