Why convert PLT to BMP?
PLT is the usual extension for HPGL plot files, written by CAD, sign-making and cutting-plotter software when a drawing is sent to a plotter or saved for plotting. The plotter's pen movements are replayed by hp2xx to rebuild the drawing's linework, which is placed on a white page and rendered at 144 dpi.
BMP stores every pixel uncompressed, so the image is exact and simple to read by any software that handles Windows bitmaps.
Frequently Asked Questions
How do I convert PLT to BMP?
Drop your PLT file above and press Convert. Our servers replay the PLT's HPGL commands with hp2xx into vector EPS, turn that into a PDF with Ghostscript, and render the page as the image you chose. The result is saved as an uncompressed BMP bitmap, ready to download.
What sort of PLT files turn into a BMP here?
PLT files that hold HPGL plotter commands, as written by CAD programs, sign-making tools and vinyl-cutting software.
What happens to the pen paths in a PLT file when it becomes a BMP?
hp2xx replays the pen-down moves as vector lines, Ghostscript lays them onto a PDF page, and that page is rendered at 144 dpi into the BMP, so plotting and cutting paths appear as clean outlines.
What happens when a PLT file fills several BMP pages?
Each page is rendered at 144 dpi and saved as its own BMP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one BMP file.
What kind of BMP does the PLT converter create?
A standard Windows bitmap with every pixel stored uncompressed, so the image is an exact copy of the rendered result.
Is my .plt file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
