This tool provides a detailed, per-image breakdown of every raster image in your PDF. For each image it reports pixel dimensions, printed dimensions, effective horizontal and vertical DPI, and the colour space, giving you complete visibility into image quality.
Knowing exactly which images are below resolution and by how much lets you target your fixes rather than guessing or replacing everything. This focused approach saves time during prepress and ensures every image in the file meets your printer's requirements.
The DPI checker gives you a summary with the lowest DPI and counts. This tool shows every image individually with full details, so you can identify exactly which images need attention rather than just knowing there are problems.
This happens when an image's pixels are not perfectly square or when it has been stretched non-uniformly to fit a layout. Both values should ideally match for undistorted print output.
The best approach is sourcing a higher-resolution version of the image. AI upscaling tools can also help for moderate cases, though they cannot fully recreate detail that was never captured.
This typically means the image uses a non-standard or custom colour space that the tool could not classify. It does not necessarily indicate a problem, but you should verify the colour space in a PDF editor if print accuracy is critical.
No. This tool is read-only and provides analysis only. You will need to replace or modify images in a PDF editor or in your original design file and then re-export the PDF.
Check the effective DPI of raster images in your PDF to ensure they meet print resolution requirements.
Verify whether your PDF includes the correct bleed area for professional printing.
Quickly check whether your PDF uses CMYK or RGB color spaces — important for print accuracy.
Check whether all fonts in your PDF are properly embedded — a common requirement for commercial printing.
Run a comprehensive preflight check on your PDF to see if it's ready for professional printing.
