Changes DPI metadata only — pixel dimensions are not resampled. Most print services require 300 DPI.
What this tool does
DPI (dots per inch) is a metadata value that tells printers how many pixels to print per inch. Most screens display at 72 or 96 DPI; most print services require 300 DPI or higher. PixelForge lets you set the DPI metadata across your entire image library in one batch — without resampling or changing pixel dimensions — so your images print at the correct size and resolution.
Problems it solves
- Preparing web images for print by setting DPI to 300 before submission
- Correcting DPI metadata on images exported from design tools at wrong resolution
- Setting consistent DPI across a batch before sending to a print-on-demand service
- Preparing photos for large-format printing at 150 or 300 DPI
Example
Set 200 product photos to 300 DPI before sending to a print vendor
Frequently asked questions
Does changing DPI resize or resample my images?
No — PixelForge changes only the DPI metadata embedded in the file. The actual pixel dimensions (width and height in pixels) remain unchanged. Changing DPI tells the printer how large to print each pixel, but does not add or remove any pixels.
What DPI should I use for print?
Most professional print services require 300 DPI for standard print. Large-format prints (posters, banners) typically use 150 DPI since viewing distance is greater. Screen images typically use 72 or 96 DPI.
My printer says my images are low resolution — will changing DPI fix it?
It depends. If your images have enough pixels for the print size (e.g., a 3000×3000px image can print at 10×10 inches at 300 DPI), changing the DPI metadata will fix it. If your images genuinely lack pixels, you would also need to resize/upsample them.
Is changing DPI a Pro feature?
Yes — DPI adjustment is available on Pro and Business plans.
