Online forms and applications often only accept photos under a set size, such as 100 KB, 50 KB or 20 KB. Choose one photo and the size you need; you get a JPG that fits.
See-through parts of PNG images become white.

Questions
How does it get the photo under 100 KB?
It makes the photo smaller in pixels, about right for the size you picked, then finds the best JPG quality that fits. If that isn’t enough, it makes the photo a little smaller and tries again. If it can’t get there without making the photo tiny, you’re told.
Is 100 KB here the same as on my form?
Here 100 KB means 100,000 bytes. Forms that count 1 KB as 1,024 bytes allow 102,400, so the photo fits either way.
Can I pick 50 KB, 20 KB or 200 KB?
Yes. How small also offers Under 500, 200, 50 and 20 KB, and the quality levels of Compress Image.
Will it look worse?
Smaller sizes look softer, especially at 20 KB. You see the new size in pixels and in KB before you save.
What if my photo is already under 100 KB?
We tell you, so you can keep the one you have.
Which images work?
JPG, PNG, HEIC and other photos your browser can open, up to 100 MB. You get a JPG. Location and other hidden photo details are removed.
Are my photos uploaded?
No. The photo is compressed on your phone or computer. We only collect anonymous usage counts and error reports, listed on the privacy page.
