RRB Technician Photo & Signature Size — Live Photo + Signature Resizer, Free

Railway Recruitment Boards take the RRB Technician photo live during the application, so the only image you prepare is the signature. Sign in black ink on white paper, photograph it, and this tool crops to the ink, whitens the paper and keeps the file between 30 and 49 KB at the right shape. It runs on your device — nothing is uploaded.

For RRB Technician (CEN 02/2025), you don't upload a photograph — RRB captures a live photo by webcam or your phone's front camera. The image you upload is your signature: a JPG/JPEG of 30–49 KB, at least 140 × 60 pixels, in running handwriting with black ink on white paper, inside a 35 × 20 mm box.

100% private — your images never leave your device. No upload, no sign-up. Check it yourself: once this page loads, it works with your internet switched off.

Heads upNo photo upload: RRB captures your photo live by webcam or the phone's front camera (plain background, dark non-white clothing, no cap, mask or glasses). Photographing a printed photo gets the application rejected. This tool prepares the signature — switch to Photo above the upload box if another form needs a passport-size photo.

FAQ

Frequently asked questions

What is the RRB Technician signature size?

JPG/JPEG between 30 KB and 49 KB, at least 140 × 60 pixels, signed in running handwriting (not block capitals) with black ink on white paper inside a 35 × 20 mm box. This tool keeps the file inside 30–49 KB, padding a very clean scan up to the minimum.

Do I upload a photo for RRB Technician?

No. The application module captures a live photo with your webcam or phone camera, with a preview and retake. Blogs that quote a 30–70 KB photo are describing older cycles.

Can I choose the file size, and will the photo stay sharp?

Yes. Pick the size your form needs from the selector above the upload box. The photo is rendered at a high resolution and the exact proportions your form expects, so it stays sharp — a larger size keeps more detail, while a smaller size softens the image slightly rather than turning blocky. The default matches the size most forms ask for.

Will there be white space around my signature?

No. The tool finds your signature on the page, crops to it and turns the paper pure white, so the signature fills the box — even from a phone photo of a whole sheet with shadows. If it picks the wrong area, tap Adjust crop and drag the frame; what's inside the frame is exactly what you download. If you upload a photo instead of a signature, it fills the box with no white borders.

Is my photo uploaded anywhere?

No. The tool runs inside your browser, so your photo is read and processed on your own phone or computer and never sent to our servers or anyone else's. We never receive it, so we can't see, keep or share it — which makes it safe for sensitive documents like Aadhaar, PAN, passports and bank statements.

Is this tool really free? Is there a daily limit?

Yes, it's free with no daily limit. Because the work happens on your device, an extra photo costs us nothing — so there's no cap, no watermark and no account needed. Process as many files as you like.
