Hey Product Hunt! šŸ‘‹ I built DPI Converter after getting tired of print shops and stock photo sites rejecting images because they were "72 DPI instead of 300." Most online DPI tools make you upload your file to a server ā€” which felt unnecessary and a little risky for client photos or personal images. So I built this to run entirely in your browser. Drop in an image, pick a target DPI, get a live preview of exactly how it'll print, and download ā€” nothing ever touches a server. A few things I'm proud of: āœ… 100% private ā€” Canvas API processing, no uploads āœ… Batch convert up to 50 images at once āœ… Built-in DPI checker and DPI calculator āœ… Totally free, no account needed Would love your feedback ā€” especially if you're a photographer or designer who deals with DPI headaches regularly. What would make this more useful for your workflow?
