Resizing a photo to 150 KB, reducing image size to 150 KB and a photo KB reducer all mean the same: a JPG file of 150 KB or less.
- Choose a JPG, PNG or WebP image up to 300 MB. The 150 KB limit is already selected.

- For a signature or document, tick Black and white for sharper lines.
- Press Compress image, check that it says “Under 150 KB” and the preview looks clear, then download.
WaterPDF finds the highest JPG quality that fits. If you keep the original size and that is not enough, the picture is made smaller in pixels. Your original image is never changed.
