Is it possible to set your output file for the Clip Raster by Mask Layer tool as a jpg and not a tiff? Are there extra parameters or commands I can use to do this?

I can export as tiff and convert to jpg with another program but I am doing this for a large amount of features and it's extremely inefficient.

  • OT: Some image-editing software, like xn-view, offer batch operations, e.g. when it comes to conversion.

  • Thanks Erik I have been using Adobe Bridge for batch conversion but It still takes five times as long to convert them as it does to produce them with the Clip Raster by Mask function. I'm working with a large number of images so it's essential that I clip straight to jpeg. If there is some extra parameters to do this, it would change everything. Thank you though Commented Jan 17, 2019 at 17:10
  • Maybe I can find some python code to add in the console. Commented Jan 17, 2019 at 17:17

You can save the output image using Clip raster by mask layer tool as JPG if you want. Just select from the dropdown menu of Files of type the JPG format instead of TIFF format, as you can see below:

Although the JPG format is listed in the output file formats, it looks like it is not supported as a valid raster format for clip image. I also tried using the Clip tool located in the main toolbar from Raster -> Extraction -> Clipper and I chose .jpg as output raster file format, and I received the following error:

Output driver `JPEG' not recognised or does not support direct output file creation.

And it shows which file formats are supported:

The following format drivers are configured and support direct output:
VRT: Virtual Raster
GTiff: GeoTIFF
NITF: National Imagery Transmission Format
HFA: Erdas Imagine Images (.img)
MEM: In Memory Raster

To answer your question, you need to choose any format from the formats listed above and it should work. JPG format is not supported as direct output.

  • Thank you so much for your reply, sorry I've been busy. I have tried this many times but it gives me no output. It will only create a tif file in the folder I choose, other file types will just run but output no image.?? any ideas? Commented Feb 6, 2019 at 18:16
  • In the console log I can see this "Output driver 'JPEG' not recognised or does not support direct output file creation. Anyway to change this?? Commented Feb 6, 2019 at 20:25
  • @MikeWalters I have updated my answer. JPG format is not supported as direct output although it is listed in output file formats.

  • @ ahmadhanb Thanks again for the answer. I also noticed that. If I really wanted to create a jpg do you know where if anywhere in qgis I can find the source code for "Output driver"?? Commented Feb 7, 2019 at 23:22
  • @MikeWalters I think the clip tool relies on gdalwarp: gdal.org/gdalwarp.html where you can define the cutline and the -of: gdal.org/formats_list.html. However, based on the format list defined in gdal library, you cannot create .jpg format, but you can copy and do georeferencing. I think this is the answer to your question. You cannot create a JPEG file.
