Grayscale PDF for researchers
Updated July 2026
Arthize lets researchers and academics convert a PDF to grayscale in a private workspace — free, with no watermark. Converting a PDF to grayscale removes colour from every page, which cuts file size and prepares a document for black-and-white printing.
Why researchers convert a PDF to grayscale
A researcher merges a paper with its appendices, extracts a results table into Excel for re-analysis, and compresses the figure-heavy submission under a journal's upload limit — privately.
Built for papers. Whether it's papers, datasets, appendices, Arthize's grayscale pdf keeps the work inside your private workspace. Unpublished work and grant applications are confidential; a private workspace keeps them out of public tools.
