Resize Image to 20 KB, 50 KB, 100 KB or Any Size Online — Free Photo Compressor
Reduce a photo or signature to the exact file size a form asks for. Enter the size in KB or MB, and this free image resizer balances quality and dimensions to get as close to your target as possible — for SSC, UPSC, railway, bank, passport and other online applications.
Why forms reject photos
Online application forms usually set a maximum file size — often 20 KB for a signature, 50 KB for a passport-size photo, 100–200 KB for a scanned certificate. A phone photo is several MB, so the upload is refused. Manually trying different settings wastes time; this tool searches for the right combination for you.
How to reduce image size in KB
- Select your image — JPG, PNG, GIF, WebP, BMP, AVIF, HEIC/HEIF, TIFF or ICO, up to 50 MB.
- Type the target size and choose KB or MB (for example 50 KB).
- Press “Resize Now”. The tool tries quality and size combinations automatically.
- Compare and download — you see original and new size, the old and new dimensions and a quality rating. You can also download the result as a PDF.
Common target sizes
| Use | Typical limit |
|---|---|
| Signature upload | 10–30 KB |
| Passport-size photo on exam or job forms | 20–100 KB |
| Aadhaar / ID or certificate scan | 100–500 KB |
| Email or WhatsApp sharing | 200 KB – 1 MB |
Tips for a sharper result
- Start from the original photo, not a screenshot or a photo that was already compressed.
- If the tool has to shrink dimensions to reach a very small size, use the Pixel Resizer when the form also demands an exact width × height such as 200 × 230 px.
- Need a passport-size photo for print? Use Passport Photo Studio for the correct 35 × 45 mm layout.
