Are my files uploaded to a server?

No. GetResize processes your files inside your own browser. They never leave your device, so the tool is private and works fast even on slow connections.

Does changing DPI improve quality?

No. Quality depends on the number of pixels. DPI only decides how large the image prints: more DPI means a smaller, sharper print.

Does it work with WebP, GIF or AVIF?

Yes, but these formats have no place to store a DPI value, so they are saved as PNG with exactly the same pixels and the DPI you chose.

About Change DPI

DPI (dots per inch) tells printers and apps like Word how big to print an image. Many forms and print shops ask for 300 DPI. For JPG, PNG and BMP files, changing the DPI here only edits that setting: the pixels, and so the quality and file size, stay exactly the same.

The result shows the print size at the new DPI. To actually add or remove pixels for a print size, use “Resize Image in CM”.
