Compress Image to 20KB Online
Many government exam forms cap your photo or signature at 20KB. Upload your image, crop it to the size you need, and this tool compresses it as close to 20KB as possible without an avoidable quality loss — all inside your browser.
Compress Image to 20KB'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.

Removes paper shadows and makes the background pure white.
Why Exam Forms Ask You to Compress Images to 20KB
Online application portals for SSC, SBI, state PSCs and police recruitment handle lakhs of uploads in a few weeks, so they keep files tiny. A modern phone photo is 2–5MB — that is 100 to 250 times bigger than a 20KB limit. If you upload it as it is, the portal shows "file size exceeds limit" and you cannot move to the next step.
How to Compress an Image to 20KB
- Upload your JPG, PNG or HEIC photo in the tool above.
- Set the width and height your form asks for, or keep the default.
- Drag and zoom to crop out extra background so the subject fills the frame.
- Download — the tool shows the final file size in KB before you save it.
Best Quality at 20KB — How It Works
Most free compressors pick one fixed quality setting and hope for the best. This tool tests quality levels one after another, homing in on the highest JPEG quality that still stays under 20KB. Only if the image cannot fit at a reasonable quality does it reduce the resolution a little. The result is a clear face and readable text even at a very small size.
Photo Resizer 20KB to 50KB for Online Forms
Many forms set both a minimum and a maximum — for example, a photo between 20KB and 50KB. If your file is under the minimum, it is rejected too. For that range use the compress image to 50KB tool, or open your exam's page (like SSC CHSL or SBI PO) where both limits are already set. Need a signature in 10KB–20KB? Use the signature resizer.
Tips for a Sharper 20KB Photo
- Crop tightly — less background means more of the 20KB goes to your face.
- Use a plain, light background; busy backgrounds take more bytes.
- Keep the pixel size no larger than the form requires.
- Save as JPG/JPEG; PNG files are far larger for photos.
Compress Image to 20KB — FAQs
How does this tool compress my image to exactly 20KB?
It binary-searches the JPEG quality level to find the highest quality that still lands under 20KB. If quality alone can’t get there, it carefully reduces the resolution as a last resort, then re-renders back to a clean output — so you still get the smallest, sharpest file possible under the limit.
Will compressing to 20KB make my photo blurry?
Some quality loss is unavoidable at very small file sizes, but the binary-search approach finds the best possible quality for your target — far sharper than a fixed low-quality export.
Can I compress a signature to 10KB–20KB with this tool?
Yes, but the dedicated signature resizer is better for signatures — it also whitens the paper background, which makes the file smaller and the strokes clearer.
Is my image uploaded to a server?
No. All cropping, compression and processing happens entirely in your browser using the Canvas API. Your photo never leaves your device.
How to reduce photo size to 20KB to 50KB in mobile without losing quality?
Open SarkariPhoto.in in Chrome or Safari on your phone, choose your exam or the Compress Image to 50KB tool, pick the photo from your gallery or camera and download. Instead of one blunt compression pass, the tool searches for the highest JPEG quality that still lands between 20KB and 50KB, and only lowers resolution if quality alone cannot get there — so your face stays sharp. No app install is needed.
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.
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.
