Will my image be exactly 50 KB?

It will be just under 50 KB, as close as we can get without going over. We count 50 KB as 50,000 bytes, so the file passes whether a form counts a kilobyte as 1,000 or 1,024 bytes.

Why did my photo get smaller in pixels?

Lowering JPG quality alone can't always reach 50 KB. When it can't, the image is scaled down step by step, just enough to fit. The result shows its new dimensions.

My PNG has a transparent background. What happens to it?

The result is a JPG, which can't store transparency, so transparent areas become white. That is usually what forms want for photos and signatures.

Is my photo uploaded?

No. Compression happens in your browser, so photos, signatures and ID scans never leave your device.

Compress Image to 50 KB reduces any photo to under 50 KB automatically. It picks the highest JPG quality that fits and only scales the picture down when quality alone isn't enough, so you get the best-looking file that meets the limit, without uploading anything.

When you need an image under 50 KB

Photo uploads on government, university and recruitment portals that cap photos at around 50 KB
Profile pictures for sites with small upload limits
Scanned signatures or thumbprints that need more detail than 20 KB allows

Every form sets its own limits. Check its instructions for the exact file size, format and pixel dimensions before you upload.

What fits in 50 KB

50 KB comfortably holds a sharp passport-size photo, and a face photo around 500 pixels across usually looks clean. Larger photos are scaled down only as much as needed to get under the limit.

How it gets your image under the limit

If the image is already under 50 KB, you get it back untouched.
Otherwise it's saved as a JPG at the highest quality that stays under 50 KB.
If even the lowest quality is too big, the picture is scaled down a little at a time until it fits.
