Frequently asked questions
What is the typical RRB / NTPC photo size in KB?
Many RRB/NTPC-style notices ask for a passport photograph as JPG around 30–70 KB (some older notices used 20–50 KB), with a physical print size near 3.5 × 4.5 cm. Always confirm the exact band on the current CEN.
Is my photo uploaded to TryQuickImg?
No. TryQuickImg runs in your browser. After the page loads you can go offline and still compress, resize, or convert HEIC — nothing is posted to a remote API.
Which compress target should I use for Railway RRB?
Prefer the KB range printed on your CEN. Common prep targets are 50 KB or 30 KB landings, or Compress Image with ?kb=70 if the upper limit is 70 KB. Resize to passport proportions first when the notice also sets print size.
Should I trust this page or the official RRB CEN?
The official CEN / RRB notice wins. Specs change by recruitment cycle. Use this page as a no-upload prep workflow, then verify format, KB min/max, and photo dimensions on the latest official document before you submit.
Where this spec comes from
These figures are commonly-cited ranges, read from the official notice by hand and re-checked on a set date — nothing here is scraped, so a number never changes without a person confirming it. The notice for your own exam year always wins.
