PDF Size Checker
Check a PDF's file size, page count, and average size per page, right in your browser. Check a single PDF, or switch to Bulk mode to check many PDFs at once in a results table. Nothing is uploaded to a server.
What gets measured
File size, total page count, and the average size per page are calculated instantly after you choose a file.
Why size per page is useful
Comparing size per page helps identify whether a PDF is unusually large for its length - often a sign of unoptimized images or fonts.
Bulk mode
Bulk mode checks every selected PDF and lists the results side by side in a table.
Common Mistakes to Avoid
Assuming a large file size always means poor quality
Solution:
Large size often just reflects high-resolution images or many pages - it isn't necessarily a problem.
Comparing PDFs with very different page counts directly
Solution:
Use the average size per page figure for a fairer comparison between documents of different lengths.
