Are my RRB photo and signature uploaded to your server?
No. Cropping, resizing and compression happen in your browser. No file is uploaded or stored.
What if the RRB notification changes the size?
Specs can change every cycle. Check the new RRB notification; if the numbers differ, paste the new requirement into the tool's “Not listed?” box or type the pixels and KB — and tell us so we can update the preset.
