Free online GTP to PDF converter

The .gtp extension identifies two unrelated file types: Guitar Pro tablature and Gerber top-paste data. This page handles both, allowing a music score or PCB layer to be rendered as a PDF for printing, sharing, inspection, or archiving.

How to tell which GTP file you have

• Guitar Pro GTP: created by early Guitar Pro releases for guitar tablature and standard notation. It can contain tracks, tuning, rhythm, tempo, lyrics, chord diagrams, effects, repeats, and playback data. It is a proprietary binary file; a text editor normally displays unreadable characters. Guitar Pro or TuxGuitar can usually identify and open it.
• Gerber GTP: a PCB manufacturing file for the top solder-paste layer. It is normally an ASCII Gerber RS-274X file generated by KiCad, Altium Designer, Autodesk EAGLE, and other PCB CAD tools. A text editor commonly shows commands such as %FSL, %MOM, G04, aperture definitions, and coordinate records beginning with X or Y.

A file such as board.gtp containing readable Gerber commands is a PCB layer, not a song. A binary file associated with a score, tab, or rehearsal project is the Guitar Pro variant. The extension alone is not sufficient identification, particularly when files have been renamed.

PDF as the output format

PDF stores rendered pages with fixed layout, page dimensions, text, vector graphics, and images. It preserves the visible notation or PCB artwork for distribution and printing, but does not retain the editable musical structure, playback data, PCB layers, apertures, netlist, or CAD project settings.

Guitar Pro tablature to PDF

A Guitar Pro GTP file stores structured musical data rather than a finished page image. The conversion engine or desktop application interprets that data and lays out the selected tracks, standard notation, tablature, measures, lyrics, chord diagrams, and other supported elements on PDF pages.

Using this page: select Guitar tab (Guitar Pro), upload the .gtp file, start the conversion, and download the generated .pdf. Keep the original GTP file for editing and playback.

For local conversion, open the file in a compatible Guitar Pro release with File → Open, check the imported tracks and notation, then use File → Export → PDF. If direct export is unavailable, use File → Print and select the operating system's Print to PDF printer. TuxGuitar can open many Guitar Pro files and print the displayed score, but it may interpret older formats and advanced effects differently from Guitar Pro.

Check tuning, tempo, repeats, tuplets, bends, slides, harmonics, articulations, lyrics, chord diagrams, track visibility, page breaks, and clipped measures before distributing the PDF. Differences between Guitar Pro versions, fonts, margins, and notation support can change the engraving even when the notes import correctly.

Gerber top-paste layer to PDF

A Gerber GTP file describes the openings in the stencil for a PCB's top solder-paste layer. It contains drawing commands, aperture definitions, units, coordinate precision, and polarity; it does not contain the complete board design. The PDF renders only the supplied top-paste layer.

Using this page: select Circuit board (Gerber), upload the .gtp file, start the conversion, and download the PDF. The conversion is available on 101convert.com without installing software.

For local verification, open the file in KiCad Gerber Viewer or gerbv, confirm the units, polarity, mirroring, and aperture rendering, then use the viewer's print or PDF export function. Choose 100% or actual size when physical dimensions matter; use fit-to-page only for a visual reference.

Confirm a known board dimension or scale after conversion and again when printing. Gerber units and coordinate formats can be interpreted incorrectly, and a PDF that looks correct on screen can still be printed at the wrong size. A converted GTP does not reconstruct copper, solder-mask, silkscreen, drill, component-placement, or other Gerber layers; document those separately or export a composite view from a PCB tool.

Conversion limits

PDF export preserves appearance, not source structure. For Guitar Pro files, retain the original GTP alongside the PDF; for PCB work, retain the Gerber set and source CAD project. Inspect the downloaded PDF at its intended page size before printing, especially when small tablature symbols or PCB dimensions are significant.
