Compress an image to 150 KB
150 KB targets show up for marketplace listing photos, classified ads, newsletters and “keep attachments small” policies. It’s enough budget that you rarely have to compromise: at typical screen dimensions, 150 KB JPEGs look clean.
This tool compresses on your device — no upload — and shows you exactly what you got: final size, dimensions and a live preview.

How it works
- Open this page — the compressor is already set for “Compress image to 150 KB”.
- Drop your image into the box, click to browse, or paste it with Ctrl+V.
- The tool re-encodes the image on your own device until it fits the target — nothing is uploaded.
- Check the preview and file size on the result card, then download.
Quality at 150 KB
Photos up to ~1400 px: excellent. Product shots against clean backgrounds stay crisp with budget to spare.
Busy, detailed photos at 1600 px+: good; if you can see softening, drop the dimensions slightly rather than fighting for a bigger file.
Getting the dimensions right
Marketplaces typically display listings at well under 1400 px — scale to ~1400 px, compress to 150 KB, and your photos will load fast without looking compressed.
Frequently asked questions
Why do my listing photos need compressing at all?
Some marketplaces hard-reject files over a size cap; others accept them but compress aggressively with their own settings, which can look worse than a careful compression you control yourself. Doing it locally first keeps you in control of how the result looks.
Can I compress many product photos at once?
Yes — drop the whole set. Files are processed one after another on your device, each to the 150 KB target, and you can download them individually or all together.
Does 150 KB work for email?
Comfortably. Ten photos at 150 KB is 1.5 MB — small enough for any mail system, large enough that recipients can actually see the pictures.
