When you’d use this fixer
The 72 DPI → 300 DPI conversion is something every digital download seller hits constantly. These are the four most common moments:
- After exporting from Canva, Figma, or Photoshop's web export. All three tools default to 72 DPI for screen output. The pixel count in your file is usually fine for print, but the DPI tag is wrong — this fixer corrects it without re-exporting.
- Before listing a digital download on Etsy. Etsy buyers expect 300 DPI. Soft prints from a 72 DPI source generate refund requests and one-star reviews. Run every digital download file through this fixer before publishing the listing.
- When using AI-generated images for print. Midjourney, DALL·E, and Stable Diffusion outputs are tagged 72 DPI by default. Even if you've upscaled the pixels, the metadata still says 72. Fix it before delivery.
- When converting from web mockups to print files. A mockup screenshot saved from your shop or a stock photo site arrives at 72 DPI. If you're using it as a print-on-demand source (Society6, Redbubble), the 300 DPI metadata stamp is the last step.
Common DPI-fix mistakes
Five things people get wrong when stamping DPI — each costs time or quality.
1. Believing DPI changes the pixel count
Stamping 300 DPI does not add a single pixel to your image. A 1,000-pixel image will still be 1,000 pixels after the stamp — it just prints at 3.3 inches instead of 14. If your image is too small for your target print size, you need AI upscaling, not just a DPI fix.
2. Re-exporting at higher DPI from Photoshop without changing the pixel count
If you check Photoshop's "Resample" option and bump DPI, Photoshop interpolates new pixels — producing a larger but blurrier file. The right move is uncheck "Resample" so only the metadata changes (or use this tool, which does exactly that).
3. Skipping the DPI fix because "the file looks fine on screen"
Browsers always display at screen DPI regardless of what the file metadata says. A 72 DPI file looks identical to a 300 DPI file on your monitor. The difference only shows when the buyer actually prints — which is too late to fix.
4. Stamping DPI on a file that has the wrong dimensions for the target frame
A 4,000 x 3,000 pixel image stamped at 300 DPI prints at 13.3 x 10 inches — close to but not exactly an 11x14 frame. Always verify the pixel count matches your target print size before stamping, not after. Use the poster pixel calculator or frame size finder to confirm.
5. Trusting that the upload tool preserves DPI metadata
Some platforms (especially older marketplace uploaders) strip metadata on upload. If you stamp 300 DPI and then re-upload through a tool that strips, you're back to square one. Always upload the stamped file directly to the listing — no intermediate "optimisation" step.
