Welcome to the IncreaseDPI.com FAQ page — your one-stop help center for both our tools: Increase Image DPI and Find Image DPI. Below you’ll find clear answers about usage, file safety, quality, and privacy.
DPI (Dots Per Inch) is a print measurement that tells a printer how many dots to place per inch of paper. It doesn't measure how much detail is in a photo — a blurry photo at 300 DPI is still blurry. Some print shops and submission forms require 300 DPI or higher.
You upload a photo, set your target DPI (72, 150, 300, 600, etc.), and download the result instantly. The tool sets the DPI value in the file and may resample the image's pixels to match — it does not add new detail beyond what was in your original photo.
No. Changing DPI may add pixels through resampling, but cannot add detail missing from the original — it only changes how the image is measured for print. If your original photo is low-resolution or blurry, increasing its DPI (or resizing it larger) won't make it sharper. For the best print results, start with the highest-resolution original you have.
We support JPG, PNG, JPEG, and WEBP. Support for TIFF will be added soon.
Yes! You can upload images up to 20MB. Larger images may take slightly longer to process depending on your internet connection.

It allows you to check your image’s DPI, width, height, and total resolution online without installing any software.
Visit Find Image DPI, upload your file, and instantly see details like DPI, dimensions, and pixel density.
No — it’s a read-only analyzer. It never alters or compresses your original file.
Yes, you can check multiple images one by one. A batch-check feature is planned for future updates.
Our tools work seamlessly on all modern browsers — including Chrome, Edge, Firefox, Opera, and Safari.
Yes. Your images are never uploaded — the checker reads the file entirely within your own browser, so nothing is transmitted to or stored on our servers.
Yes. The website uses HTTPS encryption to protect your connection. No user data or files are saved — ensuring complete security and anonymity.
Changing DPI changes how an image prints, not how it appears on screen. The file size might vary slightly, but visible quality remains consistent.
Yes! You can use our tools for personal, educational, or commercial work freely — including printing, graphic design, and publishing.
