Make Images Print-Ready (300 DPI)

Frequently Asked Questions

How to check image DPI?

Short answer: Upload your images above. We verify the metadata for you. Alternatively, on Windows, right-click the file > Properties > Details. On Mac, open in Preview > Tools > Show Inspector.

Does increasing DPI fix pixelation?

No. Changing DPI only changes the metadata (how tight the pixels should be printed). It does not magically add detail to a blurry low-res photo. It just tells the printer "print this smaller and sharper" rather than "print this huge and blocky".

Can I convert multiple images at once?

Yes! Our batch processor allows you to select multiple files. If you convert more than one, we'll zip them up for a clean single download.
