rm-pdf-tools is currently in a very early version, bugs are to be expected. Furthermore,
the intended use case for this tool is to be run 24/7 on a computer,
and your tablet needs to be connected to the cloud.
Right now, this tool might require more technical knowledge than hacks, however you do not run any risk of voiding your warranty or bricking your device.
Please open an issue if you find a bug or unexpected behavior!
rm-pdf-tools adds the following features to your reMarkable tablet (with an active internet connection):
See here for a demo.
In the root (top-level) directory of your reMarkable cloud, create the following directories:
/pdf-tools/ /pdf-tools/work/ /pdf-tools/merge/ /pdf-tools/original/ /pdf-tools/processed/
To clone the repository and build the binary, run
git clone https://github.com/skius/rm-pdf-tools cd rm-pdf-tools go build .
Then start the service using
./start.sh and follow the instructions to authenticate
rm-pdf-tools with your
reMarkable cloud (courtesy of rmapi).
To merge documents (currently supported are: annotated PDFs and notebooks), rename the documents
in such a manner that their alphabetical order corresponds to the desired merge order. Then move them all
/pdf-tools/merge/ directory and wait for them to be synchronized.
Then rename the
merge/ directory to
merge!/ (add a
! to the end) and wait for the tool to take over.
Once the tool finishes, the merged document will appear in
/pdf-tools/processed/ and the original documents
will be in
/pdf-tools/original/. Furthermore, the
merge!/ directory should be named
merge/ automatically again.
You can merge PDFs with PDFs, PDFs with notebooks, and notebooks with notebooks. Note that currently the resulting document will be an annotated PDF, with the usual limitations. Additionally, the template background of your notebooks will be replaced by a blank PDF page in the merged document.
A demo can be found here. (This was from before you had to rename the
merge folder to
other than that, everything works the same)
You wish to append your notebook
Homework Notes to the end of the PDF
My Uni Assignment. First,
you rename the files to
1 My Uni Assignment and
2 Homework Notes, because you want the assignment to appear before
your notes in the merged document. Then select both files (long press on the first file, short press on the second file)
and select "Move" and move them to
/pdf-tools/merge/. When you don't see any more cloud notifications, rename that
If everything worked correctly, your merged PDF should appear in
To add/delete pages of a PDF, simply create a folder in
with a name following the actions format corresponding to what you want to change about the PDF.
Then move your PDF into that folder and wait for a few seconds. If everything worked correctly, you should
now find the processed PDF with your changes in the folder
If you accidentally deleted too much, or still need the original for other reasons, you can find it in
See the demo for an example workflow.
The title of the folder you're creating in
work/ should be a comma-separated list of
An action can be:
Xpages after page
Xpages before page
-Y: delete page
Note that your title may not contain multiple references to the same page
-3,1a3 is not allowed.
Also note that the page numbers always refer to the pages of the original document, i.e.
1a1,-2 deletes the original
2nd page, not the freshly inserted page 2.
2a1,-3: insert 2 pages after page 1, and delete page 3
-10,1a1,1b2: delete page 10, insert 1 page after page 1, and insert 1 page before page 2
-1: delete page 1
Currently, this project uses pdfcpu, which only supports PDFs up to version 1.7.
This means that certain PDFs, such as those generated by ReCalendar, are not able to be edited.
