Compress a photo to under 50 KB
Exam and admission portals often ask for a scanned signature or a passport photo of 20–50 KB, and some government systems allow no more than 50 KB per image. The 50 KB limit is already selected below: drop your photos and download them ready to upload.
Drop the images you want to compress
JPG, PNG, WebP or HEIC · several at once
- Drop one or more photos onto the box, or press the button to choose them. JPG, PNG, WebP and iPhone HEIC photos are accepted.
- Leave the compression at under 50 KB. Keep the output as JPG if the image is for a form.
- Press the button to process them, check the before and after weight of each one, and download them one by one or in a ZIP.
How it reaches 50 KB
At 50 KB size matters more than quality: a 4000 px phone photo cannot fit, so CLEKARA lowers the resolution step by step and keeps the sharpest version that fits. For a signature, crop it tight first so the space is spent on the ink.
The limit is counted strictly: 50 KB means 50,000 bytes, so the file is accepted whether the website counts in thousands or in 1,024s.
What it cannot do
Very small limits force a lower resolution: a photo cannot keep 12 megapixels in 50 KB. If an image could only reach the target by becoming unrecognizable, you get the smallest reasonable version and a note saying so.
Frequently asked questions
The form also asks for exact pixels (for example 200 × 230). What do I do?
First use Resize image with the exact width and height and the “crop to exact size” option, then compress the result here to 50 KB.
Are my photos uploaded?
No. They are processed by your browser and never sent to a server.
Does it work on a phone?
Yes, including iPhone HEIC photos straight from the gallery.
Can I pick a different limit?
Yes. Choose another option in Compression, or “Custom maximum weight” to type any value in KB.
