Dimensions
Manual size, mm/cm & file-size controls
MM/cm and DPI are planning references: canvas output controls pixels, while browsers do not reliably embed DPI metadata. Use the pixel values required by the notice.

RRB photo and signature resizer FAQs
Which RRB requirements does this tool use?
This notice specifies JPEG photo 40–70 KB and JPEG running-handwriting signature 30–70 KB. It describes photo dimensions of 35 × 45 mm or 320 × 240 pixels and minimum 100 DPI. RRB CENs differ, so check the current CEN.
Are my photos uploaded to Chase Clarity?
No. The editor uses browser Canvas and File APIs. Your source image and processed image stay on your device; the page does not send image contents to Chase Clarity servers.
Does a green status guarantee my application will be accepted?
No. It only checks the technical dimensions and file-size settings you selected. The application notice, visual quality rules and the authority's portal determine acceptance.
Why can't a PNG always reach a small KB target?
PNG is lossless and Canvas does not provide a quality control for it. For strict small file sizes, a JPG is usually the practical choice when the notice permits it.
