Questions
Does changing DPI change the image?
No. DPI is only a note in the file saying how many pixels to print per inch. The pixels stay exactly the same, so there's no loss of quality and the file size barely changes.
Why does a form ask for 300 DPI?
Printers and some upload forms read that note to decide the print size. At 300 DPI, a 3000 pixel wide photo prints 10 inches wide. Each result shows the print size at the new DPI.
Will it make a small image print sharper?
No. Sharpness depends on the number of pixels. Setting 300 DPI on a small image just makes it print smaller.
Which formats work?
JPG and PNG, which both store a DPI value. WebP doesn't, so convert it to PNG or JPG first.
Are my images uploaded?
No. Your files are processed on your device. We never upload them.
