Compress Image to 40kb JPG: what to know first

Searches like "compress image to 40kb jpg" usually come from a form or portal that has a strict rule on the file. The Compress Image to 40KB gives you a file that follows it, and you can check the result before you send it.

If a form asks for a file under 40 KB, make the file, look at its size in your downloads, and repeat with a lower quality setting or a smaller picture if it is still too big. Keep the original, since quality only goes down each time you shrink a file.

Steps

1. Choose one or more images.
2. Type the size you need, in KB or MB.
3. Download the compressed image, or all of them as a ZIP.

Common questions

How does it get the image under 40KB?

It tries many quality levels and, if needed, reduces the pixel size a little, until the file is as large as possible while staying under your limit.

Is my image uploaded?

No. Everything happens in your browser, so your photo stays on your device.

What if the image is already smaller?

Then it is kept as it is, because making it smaller would only lower the quality.
