Counted with the browser's Performance API during the last job. It sees every request the page makes, but not what is inside them, so anything that is not a static download is counted above.
To check yourself: open DevTools → Network, clear the list, run the tool, and inspect each request. None will contain your file. You can also switch to offline after the page loads; tools whose engine is already downloaded keep working.

How to make a PDF under 100 KB from JPGs
Add the photos in page order and create the PDF. If the full-quality PDF is over 100 KB, the images are downscaled and re-saved as JPEG, searching for the best quality that fits. One photographed page fits easily; five is about the practical maximum at 100 KB.
Step by step
- 01Crop each photo to the document first.
- 02Add the JPGs in order.
- 03Create the PDF; the 100 KB limit is set.
- 04Check small print in the result.
Crop first, it matters more than anything
A phone photo of a certificate includes the table, your fingers and shadows. Cropping to the paper removes pixels that cost bytes, so the remaining text keeps more detail inside the same 100 KB.
How "100 KB" is counted
This page aims at 100,000 bytes or less. Upload forms disagree on what 100 KB means: some count 100,000 bytes, others 102,400 (1 KB = 1,024 bytes). A file of 100,000 bytes or less passes either rule, so you can type the limit exactly as the form writes it. The result shows the exact byte count. Windows File Explorer counts in 1,024s, so the same file can read slightly smaller there.
Questions
Does it change the page size?
No. Each page keeps the shape of its photo; only the image stored inside is smaller.
Can I use PNG or HEIC photos?
Use Images to PDF for mixed formats including iPhone HEIC; the same size limit option is there.
What if 100 KB is impossible?
You get the smallest readable PDF, a note with its size, and an option to aim for that size instead.
