This is a preliminary check of a raster file: pixel dimensions, effective resolution for the chosen size, format and colour space read from the file contents, transparency, approximate JPEG quality. It does not check ICC profiles, bleed, content or the requirements of a particular printer. No problems found does not mean the file is print-ready. Confirm the requirements and the file with your chosen printer; the decision to order printing is yours. The rules for using the Tools are set out in the Terms of Service.
Preliminary file check before printing
The tool reads selected file properties locally in your browser. It does not approve a file for printing or check the requirements of a particular printer.
Pixels, print dimensions and DPI
Effective DPI is the pixel count divided by the print size in inches. A4 at 300 DPI needs about 2480 × 3508 pixels. Changing metadata DPI alone adds no detail; sharpness also depends on image content and compression.
Format and compression
PNG uses lossless compression. TIFF can use lossless or lossy compression, including JPEG. JPEG quality is estimated from quantisation tables, not from visual inspection. SVG can contain raster images, filters and transparency; SVG receives a partial assessment.
Colour space and profile
RGB, CMYK or grayscale is read from the header. ICC profiles and colour suitability for the target print are not checked. Agree the required colour space and conversion with your printer.
Transparency
Transparency may be intentional. Its detection is information to review with the printer, and its absence does not mean that a file is print-ready.
