Convert images to 300 DPI for print
Drop your images, walk away with 300 DPI metadata stamped and ready. The standard every print lab and POD platform asks for — no design software, no math, no fuss.
Key Features
Automatic DPI conversion
Upload any image at any DPI and get a properly flagged 300 DPI file back. The converter handles the metadata and pixel density calculations automatically.
Maintains original quality
Converting DPI does not recompress or degrade your image. The pixel data stays intact while the DPI metadata is set to the print-standard 300 value.
Works with PNG, JPG, and WebP
PNG, JPEG, and WebP files are all supported. Your output format matches your input, preserving transparency for PNGs and compression settings for JPEGs and WebP.
Batch processing
Convert up to 50 images at once. Upload a full collection and download all converted files as a ZIP, saving time on repetitive manual conversions.
Print-standard output
Every file is output with 300 DPI metadata embedded. Print providers and POD platforms read this metadata to determine print quality and sizing.
Fast cloud processing
Conversion happens instantly on cloud servers. No software to install, no Photoshop needed. Upload, convert, and download in seconds.
How it works
Upload your images
Drag and drop PNG, JPG, or WebP images at any DPI resolution into the converter.
Set target DPI
Choose 300 DPI for print-standard output, the resolution required by virtually all print providers.
Download print-ready files
Get your converted files with correct 300 DPI metadata, ready to upload to your print provider or POD platform.
Specifications
When you’d use this tool
Four scenarios where this tool saves the most time:
- Fixing 50 Canva exports that came out at 72 DPI. Canva's default export is 72 DPI for screen output. Drop your batch of Canva files into the converter, hit process, get back the same files at 300 DPI. Pixels untouched, just metadata updated. Replaces the manual 'Image → Image Size' Photoshop step done one file at a time.
- Stamping 300 DPI on AI-generated images before listing. Midjourney and DALL·E outputs are tagged 72 DPI by default. Even after AI upscaling, the metadata may still say 72. Run the upscaled file through the DPI converter to stamp 300 DPI cleanly — buyers' printers interpret the file at the right size.
- Recovering from a print shop's DPI rejection. Your print shop rejected the upload as 'low resolution.' Often the actual pixels are fine but the DPI tag is wrong. Drop the file in, get back a 300 DPI version, re-upload. 90% of these rejections clear with the metadata fix alone — no re-design needed.
- Standardising a year of mixed-DPI shop assets. You have hundreds of shop assets exported across different tools (Canva, Figma, Photoshop, AI generators) — DPI metadata is all over the place. Batch-convert the lot to 300 DPI in one ZIP. Consistency across the shop's visual delivery, no per-file checking.
Common mistakes
Things to watch for, in approximate order of how often I see them:
1. Believing DPI conversion adds pixels
DPI is metadata, not detail. Converting a 1,000-pixel file from 72 to 300 DPI doesn't add pixels — it just tells the printer to interpret those pixels at higher density. If your file is too small for the target print size, you also need AI upscaling, not just a DPI tag change.
2. Stamping 600 DPI thinking it's better than 300
300 DPI is the eye's limit at typical viewing distance. 600 DPI is invisibly different but doubles file size — pushing you past Etsy's 20 MB digital download limit on larger prints. 300 is the right answer for everything except fine line art (technical drawings, maps).
3. Forgetting to re-stamp after exporting from another tool
Run a file through the DPI converter, then re-export from Photoshop or Canva — the new export may revert to 72 DPI. Always re-stamp at the very end of the workflow, just before delivery, so the metadata Google and printers see is correct.
4. Confusing listing photos with digital download files
Listing photos display on screen at 72 DPI — that's fine. The actual digital download files for buyers should be 300 DPI. Don't confuse the two: the 72 DPI tag on a listing photo is correct; the 72 DPI tag on a download file is a problem.
5. Trusting that the upload tool preserves DPI metadata
Some marketplace upload tools strip metadata during processing. If your file went through an intermediate optimisation step, DPI may be reset to 72. Always upload your stamped file directly to the listing — no 'compress my files' detour.
