How to increase a photo size to 20 KB
Signatures and small photos are often only 5–15 KB, below the 20 KB many forms ask for. This page raises the picture to at least 20 KB; it looks exactly the same.
- Choose a JPG, PNG or WebP photo or signature. 20 KB is already selected.
- Keep the size, or enter the pixels or centimetres your form asks for.
- Press Increase size, check that it says “At least 20 KB” and the preview looks right, then download.
WaterPDF saves the picture at a higher quality first. If it is still smaller, empty space is added inside the JPG, so the picture looks exactly the same. Your original image is never changed.
