Bruker timsTOF → mzML

Drop Bruker .d acquisitions (one, or a folder of many) to convert them to mzML right in your browser. Handles TDF (TIMS on, DDA-PASEF) and TSF (TIMS off), converting in parallel — nothing is uploaded; your data never leaves your machine.

One MS1 spectrum per frame (mobility-summed) and one centroided MS2 spectrum per PASEF precursor, carrying precursor m/z, charge, isolation window, collision energy, ion mobility (1/K0) and CCS — the timsconvert DDA model. Beta converter; for production-critical work cross-check against timsconvert or msconvert. Each acquisition is held in a single 32-bit address space (~4 GB), so a single very large .d may exceed browser memory; for big batches use Stream to folder.
