<p>Depending on which version of QGIS you have (3.22, 3.24 - you
can select the "translate" command in the processing toolbox
(you'll find that under gdal -> raster conversion) and either
right click the tool and run as batch process or in 3.24 you can
select the batch button from the translate menu. <br>
</p>
<p>You can grab all the imagery from a directory and convert it. I
will admit that batch processing does throw me off just a bit -
BUT - work with it and it should do what you want. <br>

<div class="gmail_default" style="font-family:"times new roman",serif">Recently i downloaded a set of MODIS Terra
surface reflectance Daily data for a fixed rectangular area of
my interest (118 daily files for each of the bands 1-4 and for
years 2000-2020), using the AppEEARS tool (NASA-USGS-LP DAAC)
in geotiff format (WGS 84; LatLong). </div>
<div class="gmail_default" style="font-family:"times new roman",serif">I wanted to convert the original data in 500 m
spatial resolution</div>
<div class="gmail_default" style="font-family:"times new roman",serif">(0.0041667 arc deg; 2985 col x 1671 row for each
scene) to 1 km resolution (0.00833333 arc deg; 1493 col x 836
row), so that i am able to create Max.value (& Min. value)
Composites (MVCs) for consecutive 8-Day periods at 1 km
resolution and then analyse the data sets for matching with
other 8-Day data series available at 1 km resolution from
Modis Terra sites. </div>
<div class="gmail_default" style="font-family:"times new roman",serif">No downloaded data from AppEEARS is automatically
'imported" to my Idrisi software (neither geotiff, nor netCDF;
same is the case with my GlobalMapper 8.0 software also; the
same formats from other sites get converted easily). The file
format could be read in my QGIS Desktop software (ver. 3.18.2;
Zurich), and then exported either in geotiff or other formats
(incl. idrisi) in whatever resolution, etc., i chose. </div>
<div class="gmail_default" style="font-family:"times new roman",serif">Although i am doing it file by file, this is a
huge back-breaking pre-processing task. </div>
<div class="gmail_default" style="font-family:"times new roman",serif">I was thinking if there is any tool in QGIS for
automatic batch processing of the data (say, 50 or 100 at one
time, once i select the "Raster datasets" and "add" them in
the given Box under "Data Source Manager"). Presently, after
adding the datafiles, i have to select one raster image at a
time and "Export" it with the desired resolution/ file format,
etc. It helps if i am able to select all the files together,
give one output resolution value and one desired file format
for all the files to be processed). It also helps if the
output data file uses the same name as given for the input
file, but allows the user to provide a short prefix to each of
them (say 4-6 letters, either replacing the first 4-6 ones, or
adding to the given names). </div>
<div class="gmail_default" style="font-family:"times new roman",serif">Once i am able to pre-process the data quickly, i
am thinking of trying my QGIS for cloud removal (by providing
a zero, No Data value to the cloud pixels) and then try it for
getting MVCs for consecutive 8-day periods.</div>
