How to make a thermal image report with your own logo

Updated 5 November 2026

After a thermal survey, the client rarely wants a folder of JPG files. They want a document: each image with its temperatures, clearly laid out, with your company name on it. This guide shows how to make a PDF report with your own logo, title and note from FLIR® radiometric JPG files in your browser — nothing to install, and the images stay on your computer — and what to put in it so that it is useful.

What goes into the report

IRBatch creates an A4 PDF with one page per image. Each page contains:

  • your report title and logo at the top, the file name, capture date and camera model;
  • the thermal image in the palette you chose, with markers for the maximum, minimum and center, and a temperature scale;
  • the visible-light photo from the same file, when the camera saved one;
  • a table with maximum, minimum, center and mean temperature in °C or °F;
  • the parameters used: emissivity, reflected temperature, distance, air temperature and humidity — and a clear mark when you overrode the values saved in the file;
  • your note (up to 1,000 characters), repeated on every page;
  • a footer on every page saying that the data is provided as-is, without interpretation, and page numbers.

The report deliberately contains measurements only. It does not rate, grade or judge what is in the image — that is your professional call, and you can write it in the note or in your own cover letter.

Step by step

  1. Prepare your logo. A PNG or JPG file works; a wide logo with a transparent or white background looks best. Very large images (over 8,000 pixels on a side) are rejected to keep the PDF small. The logo, like your images, stays on your computer.
  2. Copy the original images from the camera or the FLIR One app to your computer. Use the original radiometric JPGs, not screenshots or edited copies.
  3. Open IRBatch and drop one image to check it in the free preview: thermal image, maximum, minimum, center and temperature under the cursor.
  4. Fill in the report settings. Under Settings → PDF report, enter a title (for example the address or the job number), choose your logo and, if you like, add a note — such as the date of the survey, the weather or the camera settings you used.
  5. Choose the look. Pick the palette (iron, rainbow or grayscale) and the unit. If the emissivity or reflected temperature in the camera was wrong, set the correct values once for the whole batch.
  6. Add all images and create the PDF. With a Pro license, select all images in the folder, wait for the batch to finish and click PDF report. The report is generated in your browser and downloaded as one PDF file.

Tips for a clearer report

  • One subject per batch. A report on one switchboard, one roof or one room is easier to read than a mix. Run separate batches and you get separate PDFs.
  • Sort your files first. Pages follow the order of the files in the batch. Renaming files with a leading number (01_entrance.jpg, 02_kitchen.jpg) keeps the order you want.
  • Use the same palette throughout. Switching palettes between pages makes images look different even when the temperatures are similar.
  • Say what you measured. The note is the place for context the image cannot show: what the object is, load or operating state, and anything that affected the measurement.
  • Check emissivity before you export. The parameters are printed on every page, so a wrong emissivity is visible to the reader. Correct it before you send the report.

Want the numbers too?

The same batch can also be exported as a summary CSV (one row per image) and as a ZIP with the full temperature matrix of every image. Many people attach the CSV to the report so the client can check or reuse the figures.

Which files work

IRBatch reads radiometric JPGs saved by FLIR cameras. It has been tested on sample files from the FLIR E-series (E5), AX8, SC660 and the DJI Zenmuse XT-R (FLIR core), and on a sample file believed to be from a FLIR One (the model name is masked in the file). SEQ/CSQ files, video, DJI R-JPEG files from DJI's own thermal cameras and some older models with a different raw format (such as the FLIR i7) are not supported — you get a message instead of a wrong result. Many other FLIR cameras use the same format; open one of your own images in the free preview to check before buying.
