Why "compress to exact KB" matters
Most image compressors let you drag a quality slider and hope for the best. But forms don't ask for "good quality" — they ask for a hard limit: "photo must be under 50KB," "scan must not exceed 200KB." Guessing a quality percentage to hit an exact number wastes time. This tool does the guessing for you: it repeatedly tests compression quality using a binary search until the output lands at or just under your target size, then stops.
Everything happens locally using the Canvas API — your photo is never uploaded to a server, so there's no wait and no privacy concern, even for ID documents or personal photos.
How to compress an image to a target KB
- Upload your JPG or PNG.
- Enter your target size, or pick a common preset like "Admission form photo — 50KB."
- Click "Compress." The tool tests quality levels automatically and shows you the final file size.
- Download the compressed image, ready to upload wherever it's needed.
Common uses in Pakistan
University and college admission portals, government job application forms, CNIC and domicile scan uploads, and passport or visa photo uploads all commonly cap file size — often 20KB to 200KB. This tool is built specifically for that exact-limit situation, rather than a general "make it smaller" slider.
FAQ
Can it hit the exact size every time?
It gets as close as possible without going over your target, typically within a few KB. JPG compression works in discrete quality steps, so an exact byte-for-byte match isn't always possible, but the result will meet "under X KB" requirements.
Does it work for PNG files too?
Yes. PNGs are converted using quality-based JPG-style compression internally to hit small targets, since PNG's own lossless compression usually can't reach very small sizes like 20–50KB for photos.
Is my photo uploaded anywhere?
No — compression happens entirely in your browser. Nothing is sent to a server.
