Hi, I don't know if it's a solution for you to have a jpg instead a pdf. Jpg are easy to compress in the writer directly or using "RasterResampler" transformer.

Hi @hoanghung90​ ,

Would you be able to expand on your workspace inputs/outputs a bit? We have a number of transformers that can help with file size issues. For example, the RasterResampler jr2 mentioned would work great if you are writing raster-based PDF's. If you are writing vector-based PDF's, perhaps the Generalizer to reduce the number of vertices?

The PDF writer also has a Compress Streams option that should be enabled by default. This parameter is used to "determine whether streams in the output file will be compressed." Could you ensure this is enabled to see if that helps?

If you could expand on the details of the workspace and let us know what you are expecting in terms of file size on the output that would help us provide additional recommendations

hi @jr2​ , @chrisatsafe​ 

Thank you for your help.

It works very well with rasterresampler !
