How It Works

Step-by-step guide to resize image to 300 dpi to exact specifications

Upload your photo

Drag and drop a JPG, JPEG, or PNG photo from your phone or desktop. Product shots, portraits, and scanned documents all work the same way.

Set DPI to 300

Enter 300 as the target DPI and the tool writes it into the file's metadata. If a print shop or portal rejected your file as low resolution because of missing pixels, resize the image up first so the pixel count matches your intended print size.

Download and upload

Save the finished file and send it to your print shop, Etsy listing, or passport application. Everything ran locally in your browser, so your photo was never uploaded anywhere in between.

Why Choose Imresizer?

Fast, secure, and completely free image resizing

  • 100% private

    Passport photos, product shots, and personal prints stay on your device. The DPI change runs entirely in your browser — nothing is ever uploaded to a server.

  • The standard print DPI

    300 DPI is what photo labs, passport offices, and print-on-demand sites like Etsy and Printful expect from an upload. Tag your file at 300 DPI and clear that check on the first try.

  • Pixel dimensions matter most

    Print size works out to pixel dimensions divided by DPI, so a small photo tagged 300 DPI still prints small. Check the pixel table below before you submit to a print shop or portal.

  • Built for passport and ID photos

    Passport and visa photo requirements commonly call for 300 DPI. Set your photo to that value here before cropping it to the exact size your country's application asks for.

  • Free with no daily limit

    Resize as many photos to 300 DPI as you need for prints, uploads, or applications. No account, no watermark, and no cap on how often you come back.

Frequently Asked Questions

Everything you need to know about image resizing

How do I resize an image to 300 DPI?

Upload your photo, set the target to 300, and download the result. The tool writes 300 DPI into the file's metadata in your browser, with no software to install and no account needed.

What pixel dimensions do I need for 300 DPI prints?

A 4x6 inch print needs 1200x1800 pixels, a 5x7 print needs 1500x2100 pixels, an 8x10 print needs 2400x3000 pixels, and a US Letter page needs 2550x3300 pixels — all at 300 DPI. Tagging a file 300 DPI without enough pixels for your print size will still look soft, since print size is pixel dimensions divided by DPI.

Why does my file say low resolution even at 300 DPI?

A print shop or upload portal checks your actual pixel count against the print size you selected, not just the DPI tag. If your photo doesn't have enough pixels for that size, no DPI setting fixes it — you need a photo with more pixel detail to begin with, or a smaller print size.

Does setting DPI to 300 add detail to my photo?

Setting the DPI tag changes only the print instruction stored in the file, not the pixel data itself. If you want a sharper result, you need a higher-resolution source photo — no DPI tool can invent detail that isn't already in the pixels.

What DPI do passport and ID photos need?

Most passport and visa applications specify 300 DPI for the submitted photo. Set your photo to 300 DPI here, then crop it to the exact pixel dimensions your country's passport office requires before you upload it.

Do Etsy and Printful require 300 DPI uploads?

Print-on-demand platforms like Etsy and Printful commonly recommend or require 300 DPI files to guarantee sharp physical prints. Tag your artwork or photo at 300 DPI with enough pixel dimensions for your chosen print size before you upload it to avoid a rejection.

Is this tool free to use?

Every part of it is free — no account, no trial, and no watermark on the download. Resize as many photos to 300 DPI as you need.

Does this tool upload my photo to a server?

Nothing is uploaded. The DPI change happens entirely inside your browser, so personal photos, passport scans, and product shots never leave your device.

What file formats can I use?

JPG, JPEG, and PNG are supported. JPG suits photographs and most print-on-demand uploads, while PNG works well for artwork or graphics that need sharp edges.

Can I use this to print business cards or photo prints?

Yes — set your artwork or photo to 300 DPI and match its pixel dimensions to your print size using the table above. Most photo labs and business card printers expect exactly that combination for a clean, sharp result.
