Reduce Image Size in KB
Reduce a photo to an exact size like 20KB, 50KB or 100KB.
Your files are processed on your device and are never uploaded.
Meet the ShrinkBee Image Reducer – the quickest way to bring a photo down to an exact size in KB while keeping it sharp. Online forms for government jobs, exams, passports, scholarships and college admissions often refuse any photo or signature above a fixed limit. This tool makes your file fit that limit on the first try.
Pick a photo, type the size you need – 20 KB, 50 KB, 100 KB or any other number – and the reducer searches for the highest quality that still stays under your limit. It works with JPG, JPEG, PNG and WebP images, and everything happens inside your browser.
How to Reduce Image Size in KB
- Choose your image: Click Choose image, drag a photo onto the box, or paste one from your clipboard.
- Set the target size: Tap one of the ready sizes such as 20 KB, 50 KB or 100 KB, or type your own value in KB or MB.
- Click Compress image: The reducer tries different quality levels and keeps the best one that fits under your target – usually in a second or two.
- Download the result: Check the new size and preview, then save the reduced image and upload it wherever you need it.
Key Features
- Exact KB targets: The output always stays at or below the size you ask for, so upload forms accept it straight away.
- Best possible quality: Instead of one fixed setting, the tool searches for the highest quality that still fits, so your photo looks as good as the limit allows.
- KB or MB: Reduce a photo to a few kilobytes for a signature field, or to 1 MB or 2 MB for an email or website.
- JPG or WebP output: Save as JPG for the widest support, or WebP for even smaller files at the same quality.
- Private by design: Your photo is never uploaded to a server. It is processed on your own device and forgotten when you close the tab.
- Free and unlimited: No sign-up, no watermark and no daily limit – reduce as many images as you like.

Why Choose ShrinkBee Image Reducer?
Most compressors only let you pick "low", "medium" or "high" and leave you guessing whether the result will be small enough. ShrinkBee works the other way round: you tell it the size the form expects, and it does the guessing for you. That saves the usual cycle of compressing, checking, and compressing again.
Because nothing is uploaded, it is also fast and safe for sensitive pictures such as ID photos, certificates and signatures. Whether you are applying for a job, filling an exam form or just sending photos by email, the reducer gets your images to the right size in seconds – without losing the details that matter.
