Lower quality gives a smaller file. Around 70 to 85 is a good balance for photos.
PNG uses lossless compression, so it has no quality setting. Your PNG is saved again, which sometimes makes it smaller. For bigger savings, choose a maximum file size.
The result will be this size or smaller (1 KB = 1000 bytes).

How to compress an image to 500 KB
- Select your JPG, PNG or WebP image, or drop it onto the box above.
- The maximum file size is already set to 500 KB. You can still pick another size, enter your own or switch to Quality.
- Click Compress Image.
- Compare original and result, then download the compressed file.
Why 500 KB?
500 KB comes up in many different places: website builders, online shops, forms and email. It is large enough for a detailed photo on screen and small enough to upload and load quickly.
Many images reach 500 KB with a lower quality setting alone. Large phone or camera photos are often scaled down a little as well.
Common reasons to compress to 500 KB
- Upload limits: Forms, portals and content systems that reject images above 500 KB.
- Product photos: Shop and marketplace listings that should look detailed and still load fast.
- Website images: Larger pictures such as headers or galleries without slowing the page down.
- Email: Sharing a few good-looking photos without hitting attachment limits.
What happens if the image is too large?
The tool first lowers the quality step by step and keeps the highest quality that fits. If even a reasonable quality is not enough, it reduces the dimensions proportionally, so nothing is stretched or cropped. The result is always 500 KB or less.
Most photos reach 500 KB with quality changes and, if they are very large, a moderate reduction in dimensions. Heavy scaling is rarely needed at this size.
For very small targets and very large images there is a limit: if the image would have to become too small to be useful, the tool tells you instead of producing an unusable file.
Image quality at 500 KB
At 500 KB, most photos look very close to the original on a typical screen. You may notice a difference when zooming into fine detail. For product photos, check edges and text on packaging in the preview.
Supported formats
JPG, PNG and WebP. The compressed file keeps the format of your original. PNG is lossless, so it can only get smaller by reducing its dimensions; JPG and WebP also have a quality setting.
Your images stay on your device
Compression runs in your browser. Your image is not uploaded or stored anywhere. Very large images (over 40 megapixels) are not supported because they would exceed what a browser tab can safely handle.

Or use Compress Image to set any size or a quality level yourself.
Frequently asked questions
How do I compress an image to 500 KB?
Choose your image above; 500 KB is already selected as the maximum file size. Click Compress Image, compare the original and the result, and download the compressed file. It will be 500 KB or less.
Will the image be exactly 500 KB?
No. The tool promises 500 KB or less, not an exact size. It searches for the best quality that still fits, so a result such as 480 or 495 KB is normal.
What happens if my image is already smaller than 500 KB?
The tool tells you that no compression is needed and lets you download the original unchanged. Re-compressing would only lower the quality for no benefit.
Is 500 KB a good size for product photos?
For most shop and marketplace listings, 500 KB leaves room for a detailed, sharp photo on screen. If the platform shows a zoom view, check the preview for fine detail before you upload.
Does compressing to 500 KB reduce quality?
It removes detail that is hard to see; how much depends on how large your original is. A 2 MB photo loses very little, a 10 MB photo more. The side-by-side preview shows the result before you download it.
Which formats are supported?
JPG, PNG and WebP, and the result keeps its format. PNG has no quality setting, so it can only reach 500 KB by reducing its dimensions; for photos, JPG or WebP usually compresses better.
