Why is your PDF so large, and how many pictures does it really hold? The PDF Image Counter reads each page and counts the images drawn on it, with a page-by-page list. It helps designers, students, and office staff who need to know where the pictures are before sharing a file.
The tool only reports. It does not show, extract, or change any image in your PDF.

What the Tool Does
The tool counts image draws in one PDF and shows where they happen.
- Drag & drop PDF to count embedded images: the upload area. Drop a file or click to choose one.
- Status line: shows progress, starting as "Ready".
- Images Drawn on Pages: the heading of the results box. It shows one summary line and a list of pages.
There are no buttons, settings, or downloads. The results stay on screen until you pick another file.
How to Use It, Step by Step
- Drop one PDF on the upload box, or click it and pick the file.
- Watch the status line. It reads "Scanning page 1 of 18..." and counts up.
- Read the summary line in the results box.
- Scroll the page list to see how many images each page draws.
How It Works
The pdf.js library opens your file in the browser. For each page, the tool reads the list of drawing steps. It counts every step that paints a picture, including small inline pictures.
Choose PDF→Read each page→Count picture draws→Total and page list
A draw means one placement of a picture on a page. A logo that appears on every page counts once per page, not once for the whole file.
A Walkthrough With a Brochure
Rani has an 18-page product brochure and wants to know where the photos are. She drops the file on the upload box.
The status line ends with "Scan complete. 14 image draws found." The summary reads "14 image draws on 9 of 18 pages". The list includes "Page 1: 2 image draws (2 distinct on this page)". It also shows "Page 3: 3 image draws (1 distinct on this page)".
Page 3 shows the same picture placed three times, perhaps a logo. These numbers are an example, and your file will give its own.
How to Read the Results
- Summary line: total draws, then how many pages have at least one. A single draw reads "1 image draw".
- Page lines: the draws on each page. A page with none reads "0 image draws".
- Distinct: how many different pictures a page uses. It counts within that page only.
- Status line: "Scan complete. N image draws found." or "Scan complete. No images were drawn on any page."
Scanned documents often hold one picture per page. For those files, the draw count usually matches the page count.
What Is Not Counted
Vector art such as charts, lines, and shapes is not counted, because it is not a picture. Hidden helper images that only create see-through effects are skipped as well.
Some pictures may still be missed or over-counted. Images inside annotations or tiling patterns may not appear in the page list. A picture hidden under other content is still counted as drawn.
Tiny spacer images count like any other. For the pictures themselves, use Extract Images from PDF or the PDF Embedded Image Exporter.
Limitations and Assumptions
- The tool shows no image sizes, formats, or resolution.
- A document-wide count of different pictures is not given. Distinct counts are per page.
- Password-protected or damaged files show "This PDF could not be read. It may be encrypted, password protected, or damaged. Unlock or repair the file, then try again."
- A file that does not end in .pdf gets a message asking for a PDF.
- Large files are scanned page by page and can take a while.
- The tool keeps no copy of your file. Pick it again after a reload.
Your File Stays in Your Browser
The page reads your PDF with your browser's own file tools. Each page is scanned on your device. We found no code that sends the file to a server.
The page loads the pdf.js library from cdnjs, a public code host. That download does not include your document.
If the counts show a heavy file, the PDF Recompress Images tool may help. The PDF DPI Checker looks at picture detail. For a wider tally of a file's parts, use the PDF Object Counter. Browse more in the PDF tools hub.
FAQs About the PDF Image Counter
Why does my logo count so many times?
The tool counts placements, not stored files. A logo drawn on 20 pages adds 20 draws, but only one distinct picture per page.
Does a count of zero mean my PDF has no pictures?
It means no images were drawn on any page. The status line then reads "Scan complete. No images were drawn on any page."
Can I save the images or the counts?
No. There is no export button. You can select the text on screen and copy it by hand.
Does the tool change my PDF?
No. It reads the file and shows numbers. Your original is never edited or saved back.
Why is the count different from another tool?
Other tools may count stored images instead of draws. They may also treat vector art, masks, or inline pictures differently.
Is my PDF uploaded to a server?
The code we reviewed processes the file in your browser and does not send it anywhere. Only the pdf.js script is downloaded.
This tool runs in your web browser and may not handle every PDF file, font, or browser the same way. Keep a backup of your original file. Reviewed for general accuracy by Prof. Dr. Khalil Mudassar, PhD.
