Browser-only image tool
Compress Image to 15 KB
Reduce any photo to exactly 15 KB in your browser. No upload, no account. Ideal for strict government portals, KYC documents, and online exam registrations that enforce a 15 KB hard limit.
Compress your photo to 15 KB — free, in your browser.
Open the tool → pick your photo and set target to 15 KB
How it works (3 steps)
- Pick your photo. JPG, PNG, or WebP. The file stays in your browser — never uploaded to any server.
- Set target to 15 KB. Use the quality slider to fine-tune if the output looks too degraded.
- Download. Get the compressed photo instantly. Use it on the portal that rejected your original file.
Why 15 KB? What portals require it
Many government exam portals in India — including SSC, IBPS, and RRB — enforce a 15 KB maximum for passport-size photo uploads. This limit is not a suggestion: it is hardcoded into the upload validation system. Files above 15 KB are automatically rejected, often with no explanation beyond "invalid file size."
The 15 KB cap exists to minimize server storage costs across millions of candidate records stored in centralized government database systems. National ID registration portals apply the same limit for similar infrastructure reasons.
Perfect for...
- SSC, IBPS, and RRB exam photo uploads
- National ID and Aadhaar-linked registration portals
- Strict KYC document uploads requiring photos under 15 KB
- University admission e-forms with a 15 KB hard limit
Tips for 15 KB compression
- Use JPG output — gives the most precise control over file size at very small targets.
- Crop to passport size first — a tightly cropped face image compresses to 15 KB more cleanly than a full-body photo.
- Reduce dimensions — aim for 200×200 to 300×400 pixels before compressing. Smaller source dimensions mean less information to compress.
- Avoid PNG for 15 KB — PNG lossless format rarely hits 15 KB for standard photos. Always use JPG for this target.
FAQ
How do I compress an image to exactly 15 KB?
Open UploadReady, pick your photo, and set the target to 15 KB. The tool compresses locally in your browser. Use the quality slider to fine-tune. Download instantly — your file never leaves your device.
Why do government exam portals require photos under 15 KB?
Indian exam portals like SSC, IBPS, and RRB enforce 15 KB to minimize storage across millions of candidate records. The limit is hardcoded — photos above 15 KB are automatically rejected.
What image format should I use for a 15 KB target?
JPG is strongly recommended. JPG allows precise quality reduction, making it easy to hit small file sizes. Avoid PNG for 15 KB — it can only reduce size by shrinking dimensions.
Will the image still be clear at 15 KB?
For a standard passport-size photo at 200–400 pixels wide, 15 KB in JPG is sufficient for recognizable facial features. There will be visible compression, but the image will meet portal legibility requirements.
Does the tool store my photo after compression?
No. UploadReady processes everything locally in your browser. Your photo is never sent to any server. Once you close the tab, no trace of your image remains anywhere outside your own device.
Can I compress a PNG to 15 KB?
You can try, but PNG compression works by reducing dimensions rather than quality. Achieving exactly 15 KB as PNG may require very small dimensions. For reliable results, choose JPG as the output format.
