Be exact without guessing. Type the limit your form demands — 20 KB, 45 KB, 1 MB — drop your photo, and the engine finds the highest quality that lands precisely under it.
Every other compressor hands you a quality slider and lets you guess. ShrinkKB works backwards from the number — it searches for the highest quality that fits under your limit, and lands just beneath it.
Open the compressorIBPS wants 200×230 pixels and 20–50 KB. SSC wants 20–50 KB JPEG. The crop ratios and size bands are built in as presets — crop, compress and download without the photo ever being re-encoded twice.
See the exam presetsThere is no upload. The compression engine runs inside your own browser — which is why there's no file size limit, no waiting, and no copy of your ID photo or signature on anyone's server. Location metadata is stripped automatically; colour profiles are kept.
Try it with any photoA form limit is a number, so the tool takes a number. The output lands just under it — never over, never needlessly small.
No frameworks, no trackers, no ad clutter between you and the result. The page loads fast on a 4G phone because that's where it's used.
Not a policy promise — a technical fact. The engine is client-side, so your documents can't be stored, sold or leaked from a server that never sees them.
