About Compress Image to 500 KB
Many sites only accept images up to 500 KB. This tool finds the highest quality that fits under 500 KB, and only reduces the pixel size if it really has to, so your photo stays as sharp as possible.
Works with JPG, PNG, WebP and iPhone HEIC photos. The result is a JPG, which every form and website accepts.
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 500 KB?
It will be at or just under 500 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 500 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.
