PDF Size Checker

Inspect PDF file size, pages, dimensions, orientation, encryption status, version, and available metadata.

How to Check a PDF’s File Size

Choose one PDF, up to 25 MB. The checker only reads the file, so your original document isn’t changed.
Click Check PDF and wait a moment while it reads the file size, page count, page dimensions, encryption status, and any metadata.
Review the results in your browser. If the PDF is too big, use Compress PDF. If the pages are the wrong way up, use Rotate PDF.

Benefits of Our PDF Size Checker

Check your PDF file size in exact bytes, plus easy KB and MB totals, all in one result.

See how many pages the PDF has and roughly how much space each page uses.

Review every page's dimensions and whether it's portrait or landscape.

Find out the PDF version and whether the file is encrypted.

Read the title, author, subject, and other metadata, when the file includes them.

Your PDF isn't changed, and you don't download a modified copy.

Privacy and security

This deployment uses a short-lived server request for accurate parsing; the PDF is processed in memory and not retained.

Who uses a PDF size checker?

These are common examples; the right workflow depends on the file, required output, and your organization’s handling rules.

Record document size and page information during intake or quality checks.

Frequently asked questions

No. The checker only reads your document's properties, so your original PDF isn't changed, and you don't get a modified copy.

Metadata fields such as title, author, and subject are optional, and many PDFs don't contain them. If a field is empty, the file simply doesn't include that information.

You get the exact size in bytes, plus KB and MB values that are easier to read. That makes it simple to compare your PDF against an email or upload limit.

Yes. The checker reports the dimensions and the portrait or landscape orientation of every page, so you can spot a mixed-orientation document at a glance.

Not always. It depends on what the file is for, its image quality, its page count, and any upload or email limit you have to meet. If you do need a smaller file, use our Compress PDF tool.

It reports whether the file is encrypted when it can be inspected. For deeper checks, you may need an authorized, unprotected copy of the document.

On Windows, right-click the file and choose Properties. On a Mac, select the file and press Command + I (Get Info). An online PDF size checker goes further, with the page count, page dimensions, PDF version, and metadata.

You can check one PDF at a time, up to 25 MB. The results show the file size, page count, page dimensions, orientation, PDF version, encryption status, and any available metadata.
