When you need a 50 KB image
Many government, exam and application portals limit uploads to 50 KB, especially for passport-size photos and signatures. Phone photos are often 3 MB or more, so they are rejected straight away.
Keep the output as JPG for these forms: it is the format they almost always expect.
How it gets a picture under 50 KB
The tool encodes your picture again and again, searching for the highest quality that still fits inside 50 KB. That keeps it as sharp as possible.
If even a low quality is still too big, because the picture has a huge number of pixels, it is also scaled down a little and the search repeats. The result note tells you which quality was used and whether the picture was resized.
Tips for tiny file sizes
Crop the picture to the required area first, since fewer pixels means a smaller file at the same quality. A signature on plain white paper compresses far better than a detailed photo.
Check the form for the required pixel size as well. If it says, for example, 200 × 230 pixels, use the Resize Image tool with those numbers before compressing.
Frequently asked questions
Are my photos uploaded to your server?
No. The conversion runs entirely inside your browser using your own device. Your files are never sent to us or to any third party, which is why it also works for private photos and large batches. Once the page has finished loading you can even switch off your internet connection and the tool keeps working.
Will a 50 KB photo still be accepted as a passport photo?
Usually yes if the pixel dimensions are right. Check the portal's rules: some require a specific width and height as well as a maximum file size.
What if my picture ends up larger than the limit?
That only happens with extremely detailed or very small pictures that cannot be compressed far enough. The tool then tells you the smallest size it could reach, and you can resize the picture first with the Resize Image tool.
