Convert your PNG to 300 DPI
Real 300 DPI — the metadata and the pixels — not just a renamed file.
Free · no watermark · your designs stay on your device
Etsy digital downloads, Amazon KDP, Printful, Printify — they all ask for “300 DPI” files, and most images fail the check for one of two reasons: the DPI label in the file says 72, or there simply aren't enough pixels for the print size.
MerchForge fixes both. It writes proper 300 DPI metadata into your PNG, and if the image itself is too small it AI-upscales the pixels (up to 4×) so the file is genuinely print-ready — not just relabelled.
It runs entirely in your browser: nothing is uploaded, there's no watermark, and it's free. Drop a whole batch at once if you're preparing a shop's worth of files.
How it works
- Step 1Drop your PNGs
One file or a whole batch — JPG and WebP work too and export as PNG.
- Step 2Pick Upscale (or a print size)
Upscale alone boosts resolution up to 4×. Or set an exact pixel size — like 4500×5400 — and it upscales to fill.
- Step 3Download 300 DPI files
Every export carries 300 DPI metadata, so design software and upload checkers read it as print-ready.
What you get
- 300 DPI metadata written into every export
- AI upscaling up to 4× so the pixels match the label
- Set exact output sizes for any platform
- Transparency preserved, PNGs compressed for upload
- Batch processing, free, no watermark
- Your files stay on your device
Common questions
What does 300 DPI actually mean?
DPI (dots per inch) is how many pixels are printed per inch of paper or fabric. A true 300 DPI file needs two things: a DPI value of 300 saved in the file, and enough pixels for the physical size — e.g. an 8×10 inch print needs 2400×3000 pixels.
Is changing DPI just renaming the file?
Changing only the label is — and some tools do exactly that. MerchForge sets the 300 DPI metadata and can AI-upscale the actual pixels, so your file passes both halves of the check.
Does Etsy require 300 DPI?
For printable digital downloads, 300 DPI is the standard buyers expect and most sellers advertise. Print-on-demand partners like Printful also recommend 300 DPI at the final print size.
Will it work for Amazon KDP?
Yes — KDP interiors and covers want 300 DPI images. Upscale your image, set the exact pixel size you need, and the export carries the 300 DPI tag.
