Recently I have not been able to access Any2DjVu, the free online site that allowed one to encode various formats, such as PDF, PBM and JPEG, as DjVu documents. Has the site been removed? I could not find any information here about this topic. The site provided results similar to the commercial DjVu encoder. I think I used the site as recently as a few months ago. Thank you.

Hi. In my experience, the largest PDF I could upload to any2djvu was about 30 MB. Above that, the conversion was still running more than 1 hour later. Have you tried to upload your PDF to pdf2djvu.com? I have not tried sending a big PDF to that site, just a suggestion.

Hi. Has anyone tried this site? pdf2djvu.com It seems to be close to any2djvu in terms of efficiency. It is a very bare site. The PDF to DjVu conversion is basically upload and download. But the quality is very good and it uses a shared dictionary! It uses DjVu Version 24, whereas any2djvu uses Version 21. The site is also available in Korean. Example: 파일을 선택 클릭 또는 여기를 드래그 Thanks.

Many screenshots in the more recent versions of video players are now being preferentially saved as lossless PNGs. Would it be worth it to add a PNG to DjVu option to the c44 section of DjVuLibre, as this section already offers JPEG to DjVu conversion, along with PGM and PPM? PNG also offers a truer rendering of characters found within images than JPEG does. This would make for better starting material, imagewise, for rendering a subsequent DjVu. The freeware program MiniDjVu Plus 1.3 offers a PNG...

Hi. Thanks, guys, for your interesting input. It looks like the MKV container system is quite extensible. I can see how any DjVu video that is based on I-frames only would be comparatively big. But it would be a cool project to somehow get a few seconds of DjVu images to play with audio in an MKV. DjVu is a format with so much still unrealized potential. The IFF Form and Chunk Registry has a number of other untested (for DjVu) forms and chunks that could be added to DjVu files. That might be another...

Hi. I recently took a video, created a sequence of thousands of jpg images from it, and then converted them to DjVu images. I then tried to put hundreds of these sequential DjVu images through an IrfanView slideshow at high speed, and IrfanView generated a slideshow that looked like a decent video! Is it possible to create a DjVu video with a new program, or would that be really difficult? Considering that one can store video as lossless pngs, and that DjVu offers more efficient compression than...
