How to check image DPI

Read the DPI tag and print size from a JPG, PNG or TIFF. Checking runs in your browser, so the file is not uploaded.

  1. 1

    Select one JPG, PNG or TIFF, up to 25 MB, or drop it onto the page.

  2. 2

    Read the pixel dimensions, DPI source, and the print size at that DPI.

  3. 3

    If you need a different print size, open Change Image DPI. Checking does not alter the file.

DPI, pixels and print size

DPI describes print density; pixel dimensions describe how much image detail a file contains. Check both before sending a file to print.

Check before printing

Read the current DPI tag, pixel width and calculated print size without changing the file.

Need a larger print?

More pixels provide more detail. Resize or use a larger original when the file does not have enough pixels.

Need a different print tag?

Open Change Image DPI when a printer requests a particular density setting.

DPI checker questions

Answers about DPI tags, print size, formats and whether the file is uploaded.

Which formats can I check?

JPG, PNG and TIFF are accepted, one image at a time, up to 25 MB.

Check JPG DPI

Is the image uploaded to the server?

No. DPI checking runs in your browser. The file is not uploaded by this tool.

Does checking DPI make the photo sharper?

No. This page only reads the existing tag. Changing DPI updates print density, not the number of pixels. Use Change Image DPI if you need a different tag.

Where does the DPI value come from?

The tool reads JFIF or EXIF data on JPG files, the pHYs chunk on PNG files, and TIFF metadata. If no tag is present, many apps assume 72 DPI.

Check PNG DPI

Can I check a TIFF file?

Yes. Drop a TIFF to read its DPI and pixel size. Other tools on this site may not accept TIFF as an input.

Check TIFF DPI

The print size is too small. Should I change DPI or resize?

If you need more pixels, resize or recapture the photo. Changing DPI only changes how large the same pixels print.

Is the DPI checker free?

Yes. It does not require an account. Check one image at a time.
