About 150KB
150KB suits document photos where small text must stay legible, such as the back of an ID or a stamped certificate corner.
For scale, 150KB is about 0.15MB. A typical 3MB phone photo has to shrink roughly 20 times to fit, so expect lower resolution and some softness. Cropping first keeps more detail.
Tips for best results
Portals that ask for 150KB usually also want a JPG file. This tool outputs JPG. If the result looks too soft, upload a higher-resolution original, because tiny or already-compressed images have little left to give.
Frequently asked questions
Is it free?
Yes, completely free with no sign-up.
Are my files uploaded anywhere?
No. Compression happens inside your browser and your file never leaves your device.
Why is my result slightly under the target?
The tool finds the highest quality that still fits under the limit you chose.
