Frequently Asked Questions

How to check image DPI?

Upload your image above — we show you the current DPI in the file list before converting. Alternatively, use our dedicated DPI checker tool.

Does increasing DPI make my image sharper?

No. DPI only changes the metadata — how the printer interprets the pixel density. It tells the printer to print tighter, not to invent new pixels. Your image quality stays identical.

Can I convert multiple images at once?

Yes. Select multiple files and we'll convert all of them and bundle the results into a single ZIP file for download.

Is my data private?

Completely. All processing happens in your browser using JavaScript. No image data ever leaves your device. We have no servers receiving your files.

What DPI do I need for Amazon KDP?

Amazon KDP requires at least 300 DPI for covers and interior images. See our KDP image guide for the full spec breakdown.
