About formats

CDT (CorelDRAW Template) is a template file format used by CorelDRAW, Corel Corporation's vector graphics editor available since January 1989. A CDT file is structurally identical to a standard CDR document — sharing the same RIFF-based container, vector object types, color definitions, and page layout capabilities — but is designated as a reusable starting point for new designs rather than a finished artwork file. When opened in CorelDRAW, a CDT creates a new untitled document pre-populated with the template's content, leaving the original template unchanged for repeated use. This workflow mirrors the template model found in office productivity suites, adapted for graphic design. CDT files commonly contain pre-built layouts for business cards, brochures, letterheads, certificates, posters, and other standardized print materials, complete with placeholder text, guide lines, bleed areas, and properly configured color spaces for print output. One advantage is workflow consistency — design teams can distribute branded templates ensuring every new document starts with correct dimensions, margins, fonts, and color palettes aligned to corporate identity standards. The format also saves significant setup time: rather than configuring document properties and recreating layout elements from scratch, designers begin with a production-ready foundation. Corel ships hundreds of CDT templates with CorelDRAW installations, and the format is supported across CorelDRAW versions with the same compatibility considerations as CDR.

PLT is a vector file format associated with HP-GL (Hewlett-Packard Graphics Language), a plotter control language introduced by Hewlett-Packard in 1977 with the HP-9872 pen plotter. PLT files contain a sequence of two-letter ASCII commands that instruct a pen plotter to move, draw lines, select pens, and render text — commands like PU (pen up), PD (pen down), PA (plot absolute), and SP (select pen) form a straightforward instruction set that directly controls physical drawing motion. The language operates on a coordinate grid measured in plotter units (typically 0.025 mm per unit), and the resulting files read almost like machine code for a drawing device. HP-GL became the dominant standard for computer-aided design output, adopted by virtually every CAD application and supported by plotters from all manufacturers throughout the 1980s and 1990s. One advantage is universal CAD compatibility — PLT files generated by AutoCAD, SolidWorks, or any engineering software can be sent directly to plotters and cutting machines without driver translation. The text-based, human-readable command structure is another strength: engineers can inspect, edit, and hand-write PLT files to troubleshoot output or generate simple drawings programmatically. HP-GL/2, an enhanced version introduced with the HP LaserJet III in 1990, added polygon fills, Bezier curves, and raster support. PLT remains actively used in engineering, architecture, and manufacturing for large-format output.

Frequently Asked Questions

Why convert CDT to PLT?

PLT is the standard format for pen plotters and cutting machines. Converting CDT to PLT sends your template graphics to hardware output.

What opens PLT files?

PLT files work with plotter control software, AutoCAD, CorelDRAW, and various CAD applications that handle HPGL data.

Is the vector data preserved as PLT?

PLT stores vector paths as pen movements, so line-based artwork from your CDT template translates directly to plotter instructions.

Can I convert multiple CDT files to PLT?

Yes — upload several CDT files at once and Convertio will batch-convert them all to PLT.

Is CDT to PLT free to use?

Basic conversions are free. Paid plans provide increased limits for high-volume production work.

Does my device matter for speed?

No. Conversion runs on Convertio servers — any device with a browser gets the same fast results.
