Frequently asked questions

What resolution do I need for 4×6 photo print?
Professional print requires 300 DPI (dots per inch). The preset on this page produces the exact pixel dimensions needed at 300 DPI for 4×6 photo print — the size that most print shops require.
Can I print at less than 300 DPI?
For posters viewed from a distance, 200 DPI is acceptable. For anything held in hand (postcards, flyers, business cards), 300 DPI is what separates professional-looking print from visibly soft output.
What format should I send to the print shop?
JPEG at maximum quality is the safest universal choice — every print shop accepts it. For designs with transparency (like T-shirt PNGs), send PNG. Ask your print shop directly if they specify a preferred colour profile.
Do I need to add bleed?
For any print with edge-to-edge design (business cards, flyers, posters), yes — typically 3 mm bleed on each edge. Talk to your print shop; their template usually specifies exact bleed dimensions.
Is my image uploaded anywhere?
No. The resize runs in your browser. Files only leave your device when you send them to the print shop.
