Compress an image to an exact KB size
Most exam boards, recruitment portals, and government forms reject photos over a strict size limit — 20 KB, 50 KB, or 100 KB are common. Set your target below and this tool will find the highest quality that still fits, right in your browser.
How to compress a photo to a specific file size
- Check the exact size limit your form or portal asks for — usually stated in KB (e.g. "under 50KB") on the upload page.
- Drop your photo into the box above, or click it to choose a file from your device.
- Enter that number in the target size field and pick KB or MB.
- Press Compress image. The tool tests several quality levels and keeps the best one that fits.
- Download the result and upload it to your form.
Common size limits by use case
- Government exam applications (SSC, Railway, Banking): often 20KB–50KB for photo, 10KB–20KB for signature.
- University admission portals: commonly 100KB–200KB.
- Passport and visa applications: size limits vary by country; check your specific form.
Always double-check the exact requirement on your form before submitting — limits vary between portals and change over time.
Frequently asked questions
How do I compress an image to exactly 20KB or 50KB?
Upload your photo, type your target size into the box, and press Compress. The tool re-encodes the image at different quality levels until it finds the highest quality that still fits under your target.
Will this reduce the quality of my photo?
Some quality loss is unavoidable when shrinking to a small size — the tool automatically picks the highest quality that still meets your target, keeping the loss as small as possible.
Is my photo uploaded anywhere?
No. Compression happens entirely inside your browser. Your photo is never sent to a server.
