Many of you would prefer to use a tablet to write your homework on and I have no problem with that.  There are two issues I see with students using a tablet:

1) Make sure it is neat.  Some students have a hard time writing with a stylus so please do practice.  When drawing a line then make sure to use a line tool rather than freehanding it.

2) Next is most tablets create huge files compared to scanning.  It doesn't make sense to me but they do.  Here are some advice from students who uses a tablet and the files are reasonable.  This is not in any particular order:

Advice 1:

Try exporting the pages as jpegs and then compiling them back together. Its very tedious but its one of the only methods that ivr found works. Jpegs are easier to compress than the layers that are often created when marking and drawing on the pdf.

Advice 2:

There are a lot of software programs that allow you to do this but the one I used is a program called drawboard linked directly below.

I use this with a drawing pad.

This particular one you do have to pay for to access all of its features. I personally justified the cost because of the need and use in my other classes that have me turn in assignments the same way as well as it being a great way to save paper.

Advice 3:

I am using a Samsung Galaxy Tab S6 Lite and a PDF markup application called "Squid."

For most students an iPad 7 10.2" and an apple pencil will probably work better. I am partial to Android but iOS is a more intuitive OS for tablets. I believe Squid is available on iPad as well.

Both tablets are the same price at Best Buy. The iPad is $250 on sale right now and the apple stylus is $100. The Samsung is $350 but includes a quality stylus.

Advice 4:

I'm using Good Notes 5 on the 2018 IPad Pro. The file tends to be about 1MB or a little bit above for 7 pages ish. Before I export the file, I turned off the handwriting recognition feature/option and (I've test it out), it reduced about 40 KB in size.
for a file compressing app:

I found that one to be the most useful and it has features modifying the DPI, image quality, and color.
I hope that help,

Advice 5:

I use Notability on my iPad, which is actually supposed to be the worse for storage. Goodnotes or OneNote is supposed to better I heard. However, I save the files as a pdf, use a pdf grayscale converter website, and compress it once or twice (using one of the two websites below). I use to use websites like smallpdf.com, but I used them so much that they wanted me to pay for the service or limited me on how many times I can use it. I only found two free, good and safe(ish) looking at pdf compressor websites that will allow me to use them as much as I want.

Grayscale: https://www.sejda.com/grayscale-pdfLinks to an external site. --- This one has a compressor too but, it doesn't work well
PDFCompressor: https://pdfcompressor.com/Links to an external site. --- If compressing twice, I use this one first
ILovePDFCompressor: https://www.ilovepdf.com/compress_pdfLinks to an external site. --- This is the best compressor I found so far.

Also, if you are going to inform other students about this, a good tip to know is to make sure to change the file's name to the original file name after compressing it. This will cause the device to replace the original file with the compressed file. Normally pdf compressor website will change the file to FileName_min or FileName_compressed. This will save storage space on the device when it is saved again and will prevent submitting the larger version of the file.
