Portals often demand 200 or 300 DPI. See the current DPI of your file and write a new value into the JPG or PNG header — the pixels stay untouched.

Frequently asked questions
Does changing DPI change my pixels?
No. DPI is metadata that tells printers how large to print. The tool rewrites only the JPG or PNG header; the pixels stay byte-identical.
Which DPI do portals ask for?
Most government and exam portals ask for 200 or 300 DPI. Choose the preset or type a custom value.
Can I see the current DPI of a file?
Yes. The card shows the DPI read from the file as soon as you add it, or Unknown if none is stored.
