Shottr can be used for free for as long as you want. Most of its features are available to free users; the main caveat is that the app will ask you to consider buying it every once in a while. Shottr generally provides a better overall experience in the activated version, and I plan to add more features and raise its price in the future.
Can Shottr upload the image online and copy link?
Shottr has the upload feature, but it needs to be activated. Here are more details on how it works.
Which macOS versions are supported?
Shottr runs on macOS Catalina (10.15) and up.
When and why does Shottr contact Shottr.cc?
After launch Shottr contacts https://shottr.cc/api/version.json to check for an update. It won't download a new version, but will notify you with a red icon in the toolbar. Shottr needs an internet connection to validate and activate the license. It also sends home telemetry to help me find bugs, measure performance and gauge popularity of certain features. Telemetry does not contain any personal or identifiable information. It's not used for advertising or retargeting purposes, and is never sold to the third parties. There's an option to turn off telemetry collection in the app Preferences. Earlier versions of Shottr included Google Analytics code, but it was removed in v1.5.1.
Do you need to convert a or a large batch of files?
A clean, high-resolution visual plot of distance (km or feet) versus attenuation (dB).
For those using VIAVI OTDRs, is an excellent, free tool that can generate detailed PDFs.
A powerful web-based application that lets you upload SOR files from any browser and export professional PDF reports.
Most OTDR manufacturers provide software that can read and analyze OTDR SOR files. Some popular OTDR software includes:
Converting an .SOR file to a portable, universally accessible format like PDF is a non‑negotiable step for professional reporting and data sharing. The fundamental reason is accessibility: while .SOR files are rich with measurement data (attenuation, reflectance, splice loss, event tables), they are essentially unusable to anyone without the proprietary OTDR viewer from specific manufacturers. Converting to PDF bridges this gap by preserving the visual trace graph and the event table exactly as the technician saw it, creating a document that can be viewed, printed, and archived by anyone.
Regardless of your choice, the shift is clear: the days of struggling with proprietary .SOR files are over. Whether you need a one-off conversion or manage thousands of fibers, there is a powerful, efficient tool ready to turn your raw test data into a clean, professional, and universally accessible PDF.
PDFs are ideal for compliance documents, project closeouts, and archiving. Top OTDR SOR to PDF Converter Solutions (Hot in 2026)
