Can I enlarge my logo to reach 4000 pixels?

Short answer: No. Enlarging a small image only zooms in on its poor quality — the file stays unusable for printing.

This is the most common mistake. Enlarging a file adds no information: the edges turn blurry or pixelated, and the logo cannot be produced.

The simplest route: upload the original vector file, as an SVG. The 4000 px question then stops arising altogether — vector artwork re-renders at any size, and we do it for each marking. See What file format should my logo be.

Failing that, always start from the largest and sharpest source you can get, then scale down to 4000 px / 300 dpi.
