When do you need a 50KB image?
Exam registration portals are the most common reason people need a 50KB image: UPSC, SSC, NEET, and hundreds of university application systems ask for a photo between 20KB and 50KB. Set the target, drop your photo, and download a file that fits the rule on the first try.

Step-by-step guides for this size
How to compress an image to 50KB
1. Add your images
Drag and drop JPG, PNG, WEBP, HEIC, GIF, BMP or AVIF files — or select them from your device. Nothing is uploaded.
2. Set the target size
Pick 50KB or type your own limit. Advanced options let you set dimensions, format and quality priority.
3. Download the result
Every file shows its before and after size. Download them individually or grab a ZIP of the whole batch.
Why this compressor actually reaches your limit
Exact target file size
Say “200KB” instead of guessing a quality percentage. A binary search finds the highest quality that still fits your limit.
Batch compression
Add up to 30 images, optimize them in one run, and download everything as a single ZIP archive.
100% private
Images are decoded and re-encoded on your own device with the Canvas API. Nothing is uploaded to any server.
Automatic resizing
When quality reduction alone cannot reach the target, pixel dimensions are reduced step by step until it fits.
Need a different file size?
Every size below uses the same optimizer with a different preset target.
Your images never leave your device
Compression runs in a Web Worker inside your browser using the HTML5 Canvas API. There is no upload step, no temporary storage and no server-side copy — which is exactly why passport photos, ID scans and exam documents are safe to process here. Read the privacy policy.
Frequently asked questions
How do I compress a photo to between 20KB and 50KB?
Set the target to 50KB. The optimizer always lands as close to the target as possible without going over, so the output is usually in the 40–50KB window that these forms expect.
The form also requires specific dimensions. Can I do both?
Yes. Open Advanced options, enter the required width and height, then run the compression. Resizing happens before compression so the final file matches both rules.
