Change the DPI of JPG, JPEG, and PNG images client-side. Set your print resolution to 300 DPI or custom values without changing pixel dimensions. Private, and instant.
Changing DPI (dots per inch) modifies the print resolution header tags of your image. This tool allows you to change the DPI of JPG and PNG images locally in browser memory without re-compressing the image, ensuring no quality loss. Standard density options include 72, 96, 150, 300, and 600 DPI.

Frequently Asked Questions
Is Change DPI free to use?+
You can open Change DPI, upload a file, and preview it for free a few times per day. Exporting/downloading the result requires DCPixel PRO — an advanced-tools upgrade that also raises the batch-processing limit (2 → 500 files) and removes the 480px resolution cap on AI-powered tools.
Does Change DPI upload my files to any server?+
Never. Every operation runs locally in your browser using the HTML5 Canvas API and WebAssembly. Your files never leave your device.
What image formats does Change DPI support?+
Check the upload area for the full list of accepted formats. Most tools support JPG, PNG, and WebP at minimum.
How long does Change DPI take to process an image?+
Typically under 5 seconds for most images. Since processing happens locally on your device, speed depends on your CPU — not server queue time.
