Inspect PDF
Know what is inside a PDF before you print, submit or send it: fonts and sizes, whether images are sharp enough, which pages are just scans, and why the file is large.

How to use
- Add the PDF you want to inspect.
- Wait while each page is read (a few seconds for a few dozen pages). “Worth a look” lists what to review, with a button to open the right tool.
- Check the fonts table (sizes, embedding), the images table (effective DPI), each page’s size and the size breakdown.
- Click any text on the page to see its font, size, color and position.
Current limits
- Font size is the text height measured on the page (pt) after all scaling — it can differ from the size chosen in the authoring app if the page was scaled.
- Text color is measured on the rendered page, so it is approximate; text over images may be measured off.
- Scanned pages have no text layer, so there is no font or size to measure — run OCR first.
- Password-protected files must be unlocked first. Links are listed, never opened.
Frequently asked questions
Is my file uploaded?
No. The file is only read in your browser, on your device; it is not changed or sent anywhere.
How can I tell if a PDF is a scan?
Scanned pages have no text layer, only images. The tool counts characters on every page and flags pages with images but no text — those need OCR before text can be searched or copied.
What does “not embedded” mean for a font?
The device opening the file has to supply that font; if it can’t, the reader substitutes another, which can shift lines or break accents. Standard PDF fonts (Helvetica, Times, Courier…) don’t need embedding.
How many DPI do I need for printing?
About 150 DPI or more for ordinary documents, around 300 DPI for good-quality photos. DPI here is based on the size the image is placed at, so the same image placed larger has a lower DPI.
Why is my PDF so large?
“Size by component” shows how much images, fonts, page content and attachments take. Images are usually the bulk — compressing the PDF then saves the most.
