How to compress a JPG to 500 KB
Phone photos are 2–6 MB. With 500 KB you keep the full look of the photo for most uses, so WaterPDF lowers the quality only a little and keeps the pixels when it can.
Resizing a photo to 500 KB, reducing image size to 500 KB and a photo KB reducer all mean the same: a JPG file of 500 KB or less.
- Choose a JPG, PNG or WebP image up to 300 MB. The 500 KB limit is already selected.
- Keep the size, or enter the pixels or centimetres your form asks for.
- For a signature or document, tick Black and white for sharper lines.
- Press Compress image, check that it says “Under 500 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.
What fits in 500 KB?
| Picture | Under 500 KB |
|---|---|
| Phone photo (12 MP) | Fits in good quality |
| Screenshot or PNG | Fits as a sharp JPG |
| JPG already under 500 KB | Kept as it is |
