How do I compress an image to your target size?

Drop your image above, keep the your target size target, and press Resize. The tool finds the highest quality that fits under your target size and only scales the image down if compression alone is not enough.

Is my photo uploaded to a server?

No. The entire process runs inside your browser. Your photo never leaves your device, which makes the tool safe for ID photos, signatures and documents.

Why was my photo rejected by the portal?

Most rejections are for being over the size limit, under a minimum, or the wrong format. Set the exact limit as your target, choose JPEG output for government portals, and re-upload.

Compress any image to an exact size

Type the file size you need — 20 KB, 50 KB, 1 MB — and get the best possible quality under it. No upload, no size limit, fully private.

Minimum quality

Keep colour profile (ICC) — recommended for photography & print

Quality is lowered only as far as the floor allows. If that still isn't enough, the image is scaled down in small steps instead — downscaling looks far better than heavy compression artifacts. EXIF metadata (location, camera, serial numbers) is always removed for your privacy; colour accuracy is kept.

Share on WhatsApp

Most compressors give you a quality slider and let you guess. ShrinkKB works backwards from the number your form actually demands: it searches for the highest quality that fits under your limit, and only scales the image down when compression alone can't get there. Presets cover SSC, UPSC, IBPS, PAN, passport uploads, email, WhatsApp and Instagram.

How it works

Set the exact target

Type the size your form demands — 20 KB, 50 KB, 1 MB — or pick a preset. The result always lands just under it.

Drop & resize

JPEG, PNG, WebP, GIF, BMP — one file or a whole batch. The engine finds the highest quality that fits your limit.

Nothing is uploaded

Every pixel is processed inside your browser. Your ID photos and signatures never leave your device.

Private by design

Nothing is uploaded — the compression runs inside your own browser using its built-in image engine. That means no size limits, no waiting for uploads, and no copies of your ID photos or signatures on anyone's server. EXIF metadata such as GPS location is removed from the output automatically, while colour profiles are preserved.
