About Compress Image to 20 KB
Many sites only accept images up to 20 KB. This tool finds the highest quality that fits under 20 KB, and only reduces the pixel size if it really has to, so your photo stays as sharp as possible.
Tip: forms often also ask for a size in pixels (for example 200×230 for a photo or 140×60 for a signature). Use Resize image first if that's required, then compress here.
Frequently asked questions
Are my images uploaded?
No. Compression happens in your browser on your own device. Your photos are never sent to a server.
Will the image be exactly 20 KB?
It will be at or just under 20 KB: the closest size we can get while staying below the limit.
Why did my photo get smaller in pixels?
Large phone photos can't fit in 20 KB at a good quality, so the tool scales them down a little first. It always keeps the original shape.
Can I choose a different size?
Yes. Change the number in the box to any size in KB or MB.
