Turn a small image into a file a print shop accepts. You pick the print size, and you get that exact size at 300 DPI with the DPI written into the file. Real-ESRGAN AI upscaling keeps the edges sharp, where a plain resize turns them blurry.
Who it is for
- Amazon KDP: coloring books, low-content books, picture books, covers. All trim sizes, with optional 0.125" bleed.
- Etsy printable wall art: 4x6 up to 24x36 posters, from one image.
- Print-on-demand: Printful, Redbubble, Society6 and local print shops.
- Anyone whose printer says "image resolution too low".
What you get
- Exact pixel size for the trim. KDP 8.5x11 at 300 DPI is 2550x3300; with bleed it is 2625x3375.
- DPI metadata in PNG, JPEG and TIFF.
- PDF: a page at the real trim size, ready for KDP.
- Landscape images rotate the preset automatically.
- Fit modes:
coverfills the page and crops the excess;containkeeps the whole image with margins;stretchdistorts it to fill.
- Transparency kept in PNG and TIFF.
- One result per image in the dataset, with the output URL and its size. A failed image is reported and not charged.
