How to use this tool

Choose a JPEG file, or drag it onto the drop area. Only .jpg and .jpeg files are accepted on this page.
Check the target size (currently 500 KB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool lowers the quality first, then reduces the dimensions step by step if the file is still too large.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you compress JPEG to 500 KB

Five hundred kilobytes is a useful middle ground between tight form limits and large originals. A JPEG of this size can usually keep full-screen detail with only subtle compression. That is why it suits situations where visual quality still matters: a portfolio preview, a product photo for an online shop, or an attachment to an email that must stay under a size cap. Compared with a 100 KB target, you retain finer textures, smoother gradients and sharper text. Compared with a 1 MB target, you save half the bandwidth with a difference that is often hard to notice on a phone. Phone photos of 4 to 8 MB typically need a moderate quality reduction, and the tool applies it in small increments so it keeps as much quality as the limit allows.

Half a megabyte keeps most phone photos looking good while cutting size dramatically, which suits email attachments and CMS uploads. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

JPEG only on this page. Keep the default 500 KB or edit the target. If you want a lighter file for web use, try 150 KB or 300 KB; if you need more fidelity, 1 MB is a reasonable step up.

Accepted input: JPEG (.jpg, .jpeg). Output is always JPEG, and transparent areas, if any, are filled with white.

Practical uses

Upload limits on forms and CMS platforms at about 500 KB
Email attachments that must stay compact but detailed
Portfolio and shop images with good quality at modest weight

Tips for a smaller file

Keep the original and compress a copy.
Compare at 100% zoom to check detail loss.
Reduce dimensions for web use to save more bytes without losing quality.
Try 300 KB if a page speed budget is tight.

Frequently asked questions

Is 500 KB the same as 0.5 MB?

Approximately. In this tool 1 MB equals 1,024 KB, so 500 KB is slightly under half a megabyte.

Will quality noticeably drop at 500 KB?

For most phone photos, the drop is slight at normal viewing size. Very large originals lose more than moderate ones.

Can I use PNG on this page?

No. This page accepts JPEG only. Use the 1 MB or 200 KB pages for PNG and WebP files.
