File sizes use decimal units: 1 KB = 1,000 bytes and 1 MB = 1,000 KB. Your image is processed on your device.

- Choose the photo you want to shrink.
- Select Prepare. The 500 KB limit and JPG format are already set.
- Check the preview, including edges and text.
- Download the JPG and use it on your site or in your email.
Compress photo to 500 KB: when this size fits
A 500 KB image suits web pages, blog posts, newsletters and forms that accept medium-sized photos. A typical phone photo of 3 to 5 MB can drop to a fraction of its size at this limit and still look sharp on most screens. Use it when you want a photo that loads quickly but keeps its detail.
If an application form needs a smaller file, the 200 KB or 100 KB page is a better match. For a larger allowance, such as a 1 MB upload, use the 1000 KB page.
Phone photos taken in low light usually compress less cleanly, so a well-lit shot tends to reach 500 KB with fewer visible changes.
Use this page to resize image to 500 KB in two clicks after you choose the photo: select Prepare, then download the JPG. The 500 KB limit and JPG format are already set. The tool checks the result against 500,000 bytes and shows a preview before you save.
Balancing quality and dimensions
The tool first adjusts JPG quality to meet 500,000 bytes. It reduces the pixel dimensions only when a quality change is not enough, and the picture keeps its proportions. A landscape photo shot at high resolution is the best candidate, because it has more detail to spare.
For the best result, use the original camera file instead of a copy sent through a chat app. Compare the preview with the original. If text or a logo looks soft, consider a larger limit when your website or form allows it.
Using the image on a website or in email
Once you download the JPG, you can add it to a website, a blog post or an email. Write alt text that describes what the photo shows, which helps readers who use screen readers and search engines understand the image.
Processing happens on your phone or computer. The image is not uploaded to a server, not stored and not shared, and the tool needs no account. The downloaded file has no watermark. Sizes are decimal, so 500 KB means 500,000 bytes.
