Questions
Does changing the DPI to 96 change my image?
Not one pixel. DPI is a note in the file header telling a printer how large to print each pixel; it has no effect on screen and does not resample anything. Setting 96 DPI means a 3000 pixel wide image prints 31.3 inches wide. If you need more actual detail you need more pixels, not a higher DPI number.
Are my images uploaded anywhere?
No. DPI Converter runs entirely inside your browser using the Canvas API. The file is read from your device, processed on your device, and the result is handed straight back to you. It never travels to a server, so there is nothing for us to store, log or leak.
Is it free, and is there a limit?
It is free with no account and no watermark. Because the work happens on your own hardware there is no per-image cost to us, so there is no quota. The only real limit is your device's memory: images beyond roughly 40 megapixels are refused rather than crashing the tab.
Does it work on a phone?
Yes. The tools work in any current mobile browser, and the result downloads to your camera roll or Files app like any other download. Very large images are slower on a phone than on a laptop because the processing is genuinely happening on the device.
