Signature Resizer 10KB to 20KB with White Background
Scan or photograph your signature, then resize it to an exact size and file-size target. Turn on the scan enhancer to remove paper shadows and get a genuinely pure white background.
Signature Resizer's photo is captured live via webcam on the official portal — no upload is accepted there. This fallback lets you prepare a standard 3.5×4.5cm photo for other purposes.
Your source image is smaller than the required output size — the result may look slightly soft. A higher-resolution original is recommended.

Signature Background Remover — Get a Pure White Background
A signature photographed on a phone rarely looks white. Room lighting turns the paper grey or yellow, and your hand casts a shadow across one side. Exam portals and verification officers often reject these as "unclear". The scan enhancer evens out the lighting across the page, then pushes the paper to pure white while keeping the pen strokes dark — the same result you would get from a flatbed scanner.
How to Resize a Signature for an Exam Form
- Sign 3–4 times on plain white paper with a black or blue ball pen; pick the cleanest one.
- Take a photo from directly above in good light, or scan it.
- Upload it above and crop tightly around the signature with a small margin.
- Switch on the scan enhancer for a white background.
- Download — the file is resized to your dimensions and compressed to 10–20KB.

Signature Resizer — FAQs
What does the signature scan enhancer actually do?
It corrects uneven lighting from phone-camera scans, then applies a contrast curve with a hard white-clamp — guaranteeing a genuinely pure white background, not just a darkened grey like most other tools.
How do I resize my signature to 10KB–20KB?
Upload a photo or scan of your signature, crop it tightly, turn on the scan enhancer, and download. The default preset is 4cm × 2cm (472×236px) at 10–20KB, which matches SSC and many other forms.
Can I use this for any exam’s signature requirement?
Yes — use the generic size here, or visit your specific exam’s page on this site for its exact pixel and KB requirement pre-filled into the tool.
How to resize signature to 10KB to 20KB with 140x60 pixels?
Open an exam page that uses a 140×60 pixel signature, such as SBI PO, switch to Signature mode, upload a clear photo or scan of your signature, crop tightly around the ink and tap Process & Download. The output is a 140×60 px JPG compressed into the 10KB–20KB range. Because 140×60 is a very small image, keep the signature dark and well-filled so the file doesn’t fall below the 10KB minimum.
How to make signature background pure white from a mobile camera photo?
Sign on plain white paper with a black or blue pen, photograph it in daylight without your phone’s shadow falling on the page, then upload it to the Signature Resizer. Keep “Clean Paper Background (Signature Enhancer)” switched on — it removes paper shadows and grey tint, turns the background pure white and keeps the ink dark. Use the Cleanup strength slider or Auto-detect if faint strokes disappear.
Why is my signature getting rejected or looking blurry on the SSC and IBPS portal?
The usual causes are a signature cropped with too much empty space (so the ink becomes tiny when resized), a grey or shadowed background, a thin ballpoint stroke, or a file squeezed far below the KB limit. Crop close to the ink, sign with a darker pen, keep the Signature Enhancer on for a pure white background, and use your exam’s exact preset — SSC wants 10KB–20KB, IBPS allows 10KB–50KB.
What are the IBPS PO and SBI Clerk photo, signature, and left thumb impression sizes?
IBPS PO (and IBPS Clerk): photo 200×230px, 20KB–100KB; signature 200×80px, 10KB–50KB; left thumb impression 240×240px, 20KB–50KB; handwritten declaration 800×400px, 50KB–100KB. SBI Clerk and SBI PO use a tighter limit: photo 200×230px, 20KB–50KB; signature 140×60px, 10KB–20KB; left thumb impression 240×240px, 20KB–50KB. All files must be JPG.
What is the photo and signature size for UPSC IAS online application form?
UPSC accepts a square photo and a square signature, each between 350×350 and 1000×1000 pixels and between 20KB and 300KB, in JPG format. The photo needs a plain white background with your face clearly visible; the signature must be handwritten in black ink on white paper and scanned — typed or digitally drawn signatures are rejected. Our UPSC IAS preset defaults to 350×350px.
How to convert HEIC or PNG photo to JPG under 50KB for online form upload?
Just upload the HEIC (iPhone) or PNG file directly — the tool converts it to JPG inside your browser and compresses it under your exam’s KB limit in the same step, so there is no separate converter needed. If your browser cannot decode a particular HEIC file, the tool tells you; export the photo as JPEG from your Photos app (or set Camera → Formats → Most Compatible) and try again.
Is it safe to upload my photo and signature on Sarkari Photo?
