How to use “Change DPI”
- Add the JPG or PNG photos whose resolution you want to change.
- Pick the DPI (300 is standard for printing) or type the exact value.
- Check the size the image will print at, or type the width you need in centimeters and the DPI is worked out for you.
- Click “Change DPI” and download the images.
What DPI is, and what changes (and what does not)
DPI (dots per inch) is a value stored in the file header that tells printers how large to print the image: a 3000 × 2000 px photo at 300 DPI measures 10 × 6.7 in (25.4 × 16.9 cm) on paper; at 72 DPI, over 41 in wide. The pixels are the same in both cases, so nothing changes on screen. This tool only rewrites that value (in a JPG, the JFIF block and the EXIF resolution, which is what Photoshop and Windows read; in a PNG, the pHYs block): the image is not re-compressed and comes out identical pixel for pixel.
Are my files uploaded?
No. ShiftAny Images processes your images directly on your device: this tool runs in your browser and never sends your files to any server.
Frequently asked questions
Does changing the DPI improve photo quality?
No. DPI adds or removes no pixels: it only says how large the image prints. If the photo is too small at 300 DPI, it lacks pixels for that paper size; enlarging it with “Resize Image” makes it smoother but does not bring back detail.
What DPI do printers and application forms ask for?
Print shops and photo labs usually ask for 300 DPI for photos and posters seen up close; 150 is enough for anything viewed from a distance. Many forms ask for “300 DPI” and only check the value stored in the file: here you meet it without altering the photo.
Why does my program still say 72 DPI?
Some viewers ignore the file’s resolution and always show 72 or 96 DPI, the screen’s. Photoshop, GIMP, Word and the file properties in Windows do read the value written here.
Does it work with WebP, HEIC or GIF?
No: only JPG and PNG store the print resolution in a way every program reads. Convert the image to JPG or PNG first with the matching conversion tool.
