Why do forms ask for a photo in KB?
Government recruitment portals, university admissions, scholarship sites and job applications usually set a strict file size range, for example 10 KB to 50 KB, plus a fixed width and height. Upload a phone photo that is 3 MB and the form simply rejects it. This tool shrinks the file to the size you specify while keeping your face and text clear.
Always check the official notification for the exact size, dimensions and format your form needs. Requirements differ between exams and change from year to year.
How the resizer keeps quality high
Reducing file size is a balance between pixel dimensions and JPEG compression. We first keep your chosen dimensions and try many compression levels to find the best one under your target. Only if the target is impossible at those dimensions do we gently scale the image down, and we tell you when that happens.
Frequently asked questions
How do I reduce photo size to 20KB?
Upload your photo, set the target size to 20 and tap Resize image. If your form also needs specific dimensions, enter the width and height first. Download the result and check the size shown under the preview.
Why is the result slightly smaller than my target?
JPEG sizes jump in small steps, so we pick the best quality that stays under your limit. A file of 19.4 KB is valid for a 20 KB limit.
Which format is the output?
The output is always JPG, the format accepted by almost every online form.
Are my files uploaded to your server?
No. This tool runs entirely inside your web browser using JavaScript. Your files are processed on your own phone or computer and are never sent to us or anyone else. You can even disconnect from the internet after the page loads and it will still work.
Can I resize a PNG or screenshot?
Yes. You can upload JPG, PNG, WebP and most other image formats. Transparent areas become white in the JPG output.
