The problem
Canva designs are sized in pixels (or in “mm/in” on Pro). The free PNG/JPG export saves at 96 DPI metadata. Print shops that auto-reject anything below 300 DPI will reject your file even if it has plenty of pixels.
Solution: design at the right pixel size, then re-tag
- Open Canva and create a Custom Size in pixels.
- For a 300 DPI print of an X×Y inch piece, set the canvas to
(X × 300) × (Y × 300)px. Use the Inches to Pixels Converter. - Design your artwork.
- Download as PNG or JPG (highest quality).
- Run the file through our DPI Converter set to 300 DPI — this rewrites the metadata tag, no resampling.
- Verify with the DPI Checker.
Canva Pro shortcut
If you have Canva Pro, the “Print” download option exports a PDF at 300 DPI with crop marks and bleed. Use that path for any print job — PNG/JPG always need the metadata correction above.
