Frequently asked questions
How do I change the DPI of a JPG?
Upload the JPG, pick a print size and 300 DPI, then download. The new file has the right pixel size and 300 DPI stored in its header.
Does converting a JPG to 300 DPI reduce quality?
The file is saved at high JPEG quality. If the original is smaller than needed, pixels are added by interpolation, which cannot add new detail.
Can I convert several JPGs at once?
Yes, upload multiple files and download them all together.
