How to compress an image to 50KB (or any size)
- Click the box above and choose your photo or scanned document.
- Select a target such as 50 KB, or type your own size like 75kb.
- Optional: set a maximum width if the form also asks for specific dimensions.
- Press Compress image, check the preview, and download the JPG.
Why forms ask for 20KB, 50KB or 200KB files
Exam portals, job applications, bank KYC forms and government sites often cap uploads at a fixed size so their servers can handle thousands of applicants. A phone photo is usually 2–5 MB, which is 40 to 100 times larger than a typical 50KB limit. Emailing it to yourself or taking a screenshot rarely gets it small enough, and many "compressor" apps only offer quality levels, not an exact size.
This tool works backwards from the size you need. You get the best-looking image that still passes the limit, instead of guessing a quality percentage and trying again.
How it works
JPG files get smaller when the compression quality goes down, and much smaller when the width and height go down. The tool runs a quick search:
- First it tries high quality at the original dimensions. If that already fits, you keep the sharpest result.
- Otherwise it searches for the highest quality that still fits under your limit.
- If even low quality is too big, it shrinks the dimensions by about 15% at a time and repeats.
Photos taken on phones are rotated correctly using their EXIF orientation, and the location and camera data stored in the original file are not copied into the new JPG.
Tips for passport photos and document scans
- Crop first. Removing empty background lets the tool keep more detail where it matters.
- Check the dimension rule. Some forms want both a size limit and exact pixels (for example a fixed width). Use the max-width box for that.
- Documents need contrast, not colour. A flat, well-lit scan of a certificate compresses far better than a shadowy photo of it.
- Need to submit a domain or ID application? Our .np domain cover letter generator creates the request letter, and this tool can shrink your scans for upload.
Questions people ask
Is my photo uploaded to a server?
No. The image is decoded and re-encoded inside your browser using the Canvas API. Nothing is sent to YourEasyTools or anyone else, and the file is gone when you close the tab.
Why is my result a JPG even though I uploaded a PNG?
JPG is the only common format whose file size can be tuned precisely with a quality setting. Transparent areas of a PNG are filled with white, which is what most application forms expect anyway.
The tool says it could not reach my target. What now?
Very small targets (for example 10KB for a large photo) may need the image to shrink a lot. The tool returns the smallest version it could make. Crop the photo to just the face or document first, then try again.
Does 50KB mean 50,000 bytes or 51,200 bytes?
We use 1KB = 1024 bytes, so 50KB means at most 51,200 bytes. This is how Windows and most upload forms measure size, so the result will pass a 50KB check either way.
Will the image dimensions change?
Only if needed. The tool first lowers JPG quality while keeping the original width and height. If that is not enough, it reduces the dimensions step by step until the file fits.
