When to analyse PDF size
When a file bounces off an email limit or a submission form, the first thing you need to know is what's making it heavy.
This tool shows the file size, page count, average size per page, and the real dimensions of every page.
How to use it
- 1Upload the PDF. Enter the password first if it has one.
- 2Check the file size, page count, and average size per page.
- 3Look through the table of per-page width and height.
- 4A high average per page usually means scanned images are involved.
Common questions
- Can it tell me which image is the heaviest?
- Not here. Breaking a PDF down object by object inside a browser has real limits, so this works from total size and per-page dimensions instead.
- What unit is pt?
- Points. There are 72 to an inch, and A4 is about 595×842pt. Wildly different values across pages mean the document was assembled from several sources.
- What do I do about a high average per page?
- Text-only documents are usually small. A high average points to scans or photos. The server-side compression tool will make a real dent once it launches.
- Does the analysis leave anything on a server?
- No. The file is opened in your browser purely to read these numbers, and nothing is transmitted.
