Frequently Asked Questions

1What DPI should I use?

72 DPI for screen viewing, 150 DPI for standard print, 300 DPI for high-quality print.

2Will downsampling make images blurry?

At 150+ DPI, most images remain sharp for print. At 72 DPI, images look great on screen but may appear soft when printed at large sizes.

3Does it affect vector graphics?

No. Only raster images (JPEG, PNG) are downsampled. Vector elements like text and shapes remain at full resolution.

4How much file size reduction can I expect?

Reducing from 300 DPI to 150 DPI typically cuts image data by 75%. Actual savings depend on the number and size of images.

Why Use ZiaSign's Downsample Images Tool?

ZiaSign's image downsampler reduces the resolution (DPI) of images inside your PDF to decrease file size while maintaining readable quality. Choose 72 DPI for screen, 150 for print, or set custom DPI.
