How to use it
- Choose or drop your photo. You can add several at once.
- The tool finds the highest quality that stays under 150 KB.
- Check the new size under the preview, then download.
When you need a 150 KB image
A 150 KB limit gives enough room for a detailed photo or a clear one-page scan. If a form rejects your photo for being too large, this page fixes it without installing anything.
The tool saves the image as a JPG and searches for the highest quality setting that keeps the file under 150 KB. If that is not enough, it reduces the width and height a little at a time and tells you when it did.
Getting the sharpest result
Crop the photo to what matters before resizing: the face for a photo, the ink for a signature. A 150 KB file shared across fewer pixels looks cleaner. As an estimate, a typical photo at 150 KB is about 950 to 1,150 pixels wide; more detail (hair, patterned clothes, busy backgrounds) means fewer pixels at the same size.
Questions
Will my photo be exactly 150 KB?
It will be just under 150 KB, usually within a few percent. Forms check that a file is not over the limit, so the tool picks the best quality that stays under it. If your form also has a minimum size, enter it in Min KB under Settings.
Why did the width and height get smaller?
If the photo cannot get under 150 KB at its original size, even at low JPG quality, the tool shrinks the dimensions step by step until it fits. If your form needs exact pixel dimensions, type them into Width and Height: the tool then keeps those dimensions and only lowers the quality.
Does the form count 150 KB as 150000 or 153600 bytes?
Websites differ, so the tool plays it safe: the file is kept at or below 150,000 bytes, which passes whether the form counts 1 KB as 1000 or 1024 bytes.
Is 150 KB enough for a scanned document?
Usually yes for one page. Tick Black and white for text documents: the text stays readable and the file gets much smaller.
Is my photo uploaded to a server?
No. The resizing runs inside your browser with JavaScript, so the image never leaves your device. Once the page has loaded, resizing keeps working even if you go offline.
