А я для таких целей пользуюсь Advanced Batch Converter.
А вот что она ещё умеет делать:
Advanced Batch Converter does exactly what its title suggests, allowing you to easily convert multiple graphics files at the click of a button. More than that, you can also edit images directly in Advanced Batch Converter, to produce a variety of effects (resize, rotate, flip, mirror, crop, filters, morphing effects, color enhancements etc). Along with the ability to batch convert you can, of course, carry out single conversions.
The program supports 22 files formats to which you can convert: bmp, dib, rle, jpg, jpeg, jpe, gif, png, pcx, tga, pcc, tif, tiff, ico, jng, wbmp, pbm, ps, eps, pdf, wmf and emf.
The original file can be in practically any current file format, as Advanced Batch Converter has support for over 90 file types: bmp, jpg, gif, giff, png, tif, jpeg, rle, dib, pcd, icb, ico, wmf, tiff, tga, pcx, scr, emf, jif, vda, jfif, rgb, afi, vst, win, cel, jpe, rgba, pic, pcc, cut, ppm, pgm, pbm, sgi, rla, rpf, psd, pdd, psp, cur, targa, bw, tar, jfi, eps (preview), int, inta, fax, jng, mng, 411, wbmp, wbm, ani, pix, thm, g3f, g3n, jp2, j2k, jpc, jpx, j2c, j, rl4, rl8, sys, tim, g3, tpi, tpic, pnm, pxm, iri, iris, rppm, rpgm, rpbm, rpxm, rpnm, rpp, rpg, rpb, rpx, rpn, bpx, avi, wap.
