> See how large a photo prints at 72, 150, and 300 DPI, or how many pixels you need. Always free. 100% private.

Online Image Converter. Language: English. https://onlineimageconverter.net/print-size

## How to start

1. Drop a photo or type its pixel width and height.
2. Read the table: physical size at 72, 150, and 300 DPI.
3. Or enter a print size and DPI to see required pixels, then open Resize.

## Notes

- Upsizing a small photo to 300 DPI at a large print size will not add detail.
- Labs care about pixels and colour. This page only does the size math.
- /dpi is the same calculator.

## Price

Always free. There is no account, no paid tier, and no watermark.

## What this site does not do

- There is no upload API, no account, and no paid tier. Photos are not sent to or stored by the site.
- Output formats are JPG, PNG, WebP, and still GIF. SVG can be opened as an input and saved as PNG with transparency.
- HEIC and HEIF can be opened in current Chrome, Firefox, Safari, and Edge. A local decoder runs in the tab when the browser cannot decode HEIC itself. AVIF stills can be opened in current browsers.
- There is no convert-to-HEIC. Animated AVIF is not supported. GIF output is a still picture. An animated GIF becomes one frame.
- This site does not make PDFs. For converting images into a PDF, use JPG to PDF on [❤️ LoveThisPDF](https://lovethispdf.com/tools/jpg-to-pdf), which also runs in the browser.
- It does not add Content Credentials (C2PA). It can strip them on Remove EXIF & GPS.
- Converting JPG to PNG keeps the picture opaque. Remove background can clear one flat colour.

## Requirements

Any phone, tablet, or computer with a browser. Nothing to install. HEIC and AVIF convert in current Chrome, Firefox, Safari, and Edge. A decoder runs in this tab when the browser cannot open HEIC itself. Very old browsers may still need a JPG from the iPhone. Very large images may fail if the device runs out of memory. Results can differ between browsers because encoders (especially WebP and JPEG quality) are implemented by the browser vendor.
