[Qgis-user] Amal Kar - India - Batch Convert of pixel resolution of satellite images

Dear Sir,
I have a set of >250 MODIS image data files of one scene at 500 m pixel
resolution (precisely: 0.00417  x  0.00417 arc degrees; 2985 col x 1671
row).
I need to convert all these files to a pixel resolution of 1000 m
(precisely: 0.00833333  x 0.00833333 arc degrees; 1493 col x 836 row), to
match with a different set of images at the same size of 1493 col x 836 row
(0.00833333  x 0.00833333 arc degrees, or 1 km pixel resolution).
I wanted to convert my images through raster processing under Batch
Convert, but did not find any clickable module that allows inputting the
pixel resolution or the arc degrees.
One can do the changes only by opening an image file, going to
"Export">"Save as", and then changing the "horizontal" and "vertical"
resolutions.
Doing this for each individual image separately takes enormous time.
I shall be highly obliged if you kindly provide me with a "Batch Convert"
link or method that can be used to process all my images to the size of
1493 col x 836 row at 1 km resolution (0.00833333  x 0.00833333 arc
degrees).
With kind regards,
amal kar.
