Compress an image to 50 KB
A 50 KB limit is the most common rule for application photos. Asset Compressor resizes and compresses your picture so it lands just under 50 KB while looking as good as possible.

How to compress a JPG to 50 KB
- 1
Choose your photo
Drop a photo from your phone, camera or scanner. JPG, PNG, WebP and AVIF files all work.
- 2
The 50 KB target is preset
Each image is scaled to at most 1000 px and saved as a JPEG at the highest quality that stays under 50 KB.
- 3
Adjust for the form if needed
Enter the exact pixel size the form asks for as the maximum width and height, or change the target to 30 or 40 KB.
- 4
Download the result
Check the size shown in the list, then download the JPEG – or a ZIP if you processed several photos.
Where you need images under 50 KB
Online applications for jobs, exams, university admissions, visas and ID services often require a recent photograph between 20 and 50 KB, usually as a JPG. Some portals also accept a signature or thumbprint under a smaller limit. Check the instructions carefully, because a file just one kilobyte too big is rejected.
When a form says 50 KB it almost always means 50 × 1024 bytes. Asset Compressor counts sizes the same way, so the number you see is the number the form checks.
Getting a sharp result at 50 KB
At 1000 px, a well-lit portrait easily fits into 50 KB with good detail. If the form specifies smaller dimensions – 300 × 400 px is typical for photos – the image will look even cleaner, because fewer pixels share the same budget.
The quality search keeps the face sharp by choosing the highest JPEG quality that fits rather than applying one fixed setting to every photo. A photo with a plain background reaches 50 KB at a noticeably higher quality than one with a busy room behind it.
Several applicants or documents at once
Helping a whole class or team apply? Add every photo at once. Each one is compressed to the same limit independently, and the ZIP download keeps the original file names, so it is easy to match photos to people.
Because the work happens in your browser, the photos never leave your device – important when they are ID or passport photos of other people.
Frequently asked questions
How do I reduce a photo from 2 MB to 50 KB?
Just add it here. The photo is scaled down to 1000 px and compressed until it fits under 50 KB – a 2 MB phone photo usually ends up between 40 and 50 KB.
Does the form also have a minimum size?
Some do, for example 20–50 KB. The quality search aims for the best quality under the maximum, so results normally land close to 50 KB rather than far below it.
Can I change the target to 30 KB or 40 KB?
Yes. Type any number into the target size field in the settings and apply again.
Is location or camera data removed?
Yes. Re-encoded JPEGs don’t keep EXIF metadata such as GPS location or camera details.
