# What should I do if my file quality looks poor after upload?

A blurry or pixelated preview almost always comes down to resolution. Print needs far more detail than a screen, so a file that looks crisp on your monitor can still be too low for press. Re-export at the correct resolution and size, then upload again. Target 300 DPI at the finished size for business cards, postcards, flyers, and similar small-format work. Large-format items like banners and posters can print well at 100 to 150 DPI because they are viewed from a distance. Avoid enlarging low-res images. Scaling a small photo up adds pixels but not real detail. Use vector art for logos and type whenever possible so edges stay sharp at any size. If the preview still looks soft after you re-export at the right settings, ask your printer to review the actual file before it goes to print.

Re-export at 300 DPI at finished size for small format work, or 100 to 150 DPI for banners and posters, never enlarge low res images, use vector logos.
