epspdf – Converter for PostScript, EPS and PDF

Ep­spdf[tk] is a TeXlua script which con­verts be­tween PostScript or EPS and PDF. It has both a com­mand-line and a GUI in­ter­face.
Us­ing pdftops (from the xpdf com­mand-line util­i­ties) for round-trip­ping opens up sev­eral new pos­si­bil­i­ties com­pared to older sim­i­larly-named util­i­ties.
