Does changing DPI in Deliteful resample or resize the image?

No. Deliteful only rewrites the DPI metadata stored in the file header. Pixel dimensions stay exactly the same and no interpolation occurs, so image quality is completely preserved.

What DPI should I use for professional print work?

300 DPI is the industry standard for offset and digital printing at final size. Large-format prints viewed from a distance can use 100–150 DPI. Fine art giclée and prepress often require 600 DPI. Check your print shop spec sheet to confirm.

Will this fix a genuinely low-resolution image?

No — if your image lacks sufficient pixels, changing the DPI tag will not add detail. DPI metadata only controls how existing pixels map to physical print size. A 300×300 px image tagged at 300 DPI will still print at 1×1 inch.

Which file formats are supported?

Deliteful supports PNG, JPEG, and WebP for DPI adjustment. The original format is preserved in the output file.

Adjust Image DPI for Print-Ready Artwork — No Resampling

Clients and print shops demand 300 DPI files, but resampling in Photoshop risks degrading carefully crafted artwork. Deliteful updates the DPI metadata stored in your PNG, JPEG, or WebP files without touching a single pixel — delivering exactly what the print spec requires.

Graphic designers frequently receive client feedback that files are 'too low resolution' even when the pixel count is sufficient — the culprit is incorrect DPI metadata, not actual pixel density. Print workflows from InDesign to RIP software read that metadata tag to calculate physical output size. A 3000×2100 px image tagged at 72 DPI will appear poster-sized in a print dialog; the same image tagged at 300 DPI resolves to a crisp 10×7 inch output. No pixels change — only the interpretation does.

Deliteful handles this as a pure metadata operation costing 1 credit per image, supporting PNG, JPEG, and WebP. You can set any value between 72 and 2400 DPI — covering everything from screen mockups to high-end prepress at 600 DPI. Because pixels are never resampled, there is zero generation loss: the file coming out is visually identical to the file going in.

How it works

1
Upload your images
Drag in one or multiple PNG, JPEG, or WebP files that need their DPI corrected.
2
Set the target DPI
Enter the required DPI value — 300 for standard print, 150 for large-format, 600 for fine art or prepress.
3
Process and download
Deliteful rewrites the DPI metadata tag and returns your files immediately, format and pixels intact.
