What you'll see
Your image opens with each channel in its own color, mixed as the microscope's software shows them, with Z, time and scenes on sliders.
- Channels • Each in its color with its own levels
- Z, time and scenes • A slider each
- Measure • Lengths in µm, with a scale bar
- Export • Save the view as PNG or the plane as OME-TIFF
About OIB
Olympus's FluoView software, for its FV1000 and FV1200 confocals, saves an image as an OIF folder or as one OIB file. Olympus's microscopes now carry Evident's name, and labs still keep years of FluoView images as OIB.
An OIB is a Compound File, the container of Office's old documents, holding what an OIF folder would: a settings file in UTF-16 with the axes, the bit depth and each channel's dye and wavelengths, a TIFF of every plane named by its channel, Z and time, and a color table for each channel.
Filepeek reads it in your browser, each plane only when it shows. Channels are mixed in their colors on your graphics card with their own levels, Z and time go on sliders, Measure gives lengths in µm, and Export saves the view as PNG or the plane as OME-TIFF.

Questions
How do I open an OIB file?
Drop it on this page or press Peek an OIB. It opens with each channel in the color FluoView gave it, with nothing to install.
Why is my OIB black in other apps?
FluoView keeps 12 bits in 16 bit planes, so in an app that shows the numbers as they are, the picture sits in the lowest levels. Filepeek sets each channel's levels from its own values.
Can I see the dyes and wavelengths?
Yes. Channels names each dye with its wavelengths, and Show details lists the objective, the microscope and when the image was taken.
What about OIF folders?
An OIF keeps the same files loose in a folder beside it, which this viewer doesn't read. FluoView saves the image again as one OIB, which opens here.
Can I save a plane for Fiji?
Yes. Export's Save the plane writes an OME-TIFF of the plane on show, every channel in its color with the pixel's size, which Fiji, QuPath and napari open as a composite.
