Resize, Convert, and Fix Image DPI Instantly
High-resolution images are great for capturing detail, but they are often terrible for the web. Large files slow down page loading speeds, hurt your SEO rankings, and are frequently rejected by upload forms on government or job application sites. This tool solves that problem instantly. It allows you to resize dimensions, convert formats (like WebP to JPG), and even adjust the DPI for professional printing—all without your photos ever leaving your device.
Why Image Dimensions and DPI Matter
In the digital world, "bigger" isn't always better. A standard website header only needs to be about 1500 pixels wide; anything larger is just wasted data that frustrates mobile users. Conversely, for physical printing, the density of pixels matters. Most screens display at 72 DPI (dots per inch), but printers require 300 DPI for sharp results. This tool bridges that gap, giving you control over both the physical size (pixels) and the print density (DPI) of your images.
How to Use the Image Resizer & Converter
Follow these simple steps to optimize your images for any use case:
- Step 1: Upload: Drag and drop your image (JPG, PNG, or WebP) directly onto the upload box.
- Step 2: Customize: Enter your desired Width/Height. If printing, set the DPI to 300. Select "WebP" for websites or "JPEG" for standard use.
- Step 3: Download: Click "Preview & Generate" to see the result, then hit "Download" to save the optimized file instantly.

Frequently Asked Questions
Why should I convert images to WebP?
WebP is a modern image format that provides superior compression for images on the web. Converting a standard JPEG or PNG to WebP can reduce the file size by 30% or more without losing visible quality, making your website load significantly faster.
Does changing the DPI to 300 improve how it looks on my screen?
No. DPI (Dots Per Inch) is a metadata instruction strictly for printers. Changing a 72 DPI image to 300 DPI won't change how it looks on a monitor, but it tells a printer to pack the ink dots tighter, resulting in a much sharper physical print.
