Common questions
Frequently Asked Questions
What DPI should I use?
72 DPI for screen viewing, 150 DPI for standard print, 300 DPI for high-quality print.
Will 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.
Does it affect vector graphics?
No. Only raster images (JPEG, PNG) are downsampled. Vector elements like text and shapes remain at full resolution.
How 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.
