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 150 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 150 KB

A 150 KB JPEG is a very practical target for the web. It is large enough to display sharp images at typical web sizes and small enough to keep pages quick on mobile networks. Marketplace listings, blog posts and CMS uploads often recommend this range. Because 150 KB leaves much more room than the strict 20 to 50 KB tiers, quality loss is mild: you gain smoother gradients, cleaner edges and enough pixels for products and faces. If your original is a multi-megabyte camera file, the tool will first lower the quality in small steps, because that preserves the pixel dimensions; the dimensions are reduced only when quality alone can't reach the target. Heavily textured scenes will need more reduction than portraits with plain backgrounds.

At 150 KB a typical photograph retains fine detail at screen sizes, which makes it a good limit for blog images and marketplace listings. 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 files only on this page. Keep the default 150 KB or edit the target. If you are publishing to the web, consider whether you need the full pixel dimensions at all, since a smaller display size may allow even better quality at the same weight.

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

Practical uses

Blog and article images with a page-speed budget
Marketplace and classified listing photos
CMS and form uploads with a mid-sized limit

Tips for a smaller file

Match the pixel width to how large the image appears on the page.
Strip unnecessary margins and borders.
Re-export from the original instead of re-compressing a compressed file.
Test on a phone to confirm the quality is acceptable.

Frequently asked questions

Is 150 KB good for website images?

It is a sensible size for many blog and listing images, though the best choice depends on your page layout and audience.

Does this page support PNG?

No. This page accepts JPEG only. For PNG and WebP, use the general 100 KB or 200 KB pages.

Can I get below 150 KB without losing resolution?

Sometimes, if the original is poorly optimised. Otherwise quality or dimensions must drop, and the tool reduces quality first.
