Check Image DPI & Print Size
Inspect image dimensions, check embedded DPI metadata when available, and estimate print size at 300 DPI. Your files stay in your browser.
Choose an image to check its DPI and print size.
How to check image DPI online
- Select an image. Choose a JPG, JPEG, PNG, or WebP file from your device. Check up to 10 images, with a maximum of 10 MB per file.
- Review pixel dimensions and metadata. The checker reads width and height, then looks for standard DPI or resolution information in the file. If it cannot find a recognizable value, it tells you instead of guessing.
- Enter your print size. Change the width and height in inches to estimate the pixel density available at the size you plan to print.
- Save a report. Download results as a CSV file for reference or comparison. Your original images remain unchanged.
What is DPI, and how is it different from PPI?
DPI means dots per inch and is traditionally used for printer output. PPI means pixels per inch and describes how many image pixels are placed into each inch of a displayed or printed image. People often use “DPI” as shorthand for both an embedded resolution setting and the effective resolution at a chosen print size.
This checker separates those concepts. When the file contains recognized resolution metadata, it displays that embedded value. It also calculates print dimensions from pixel width and height at 300 DPI, plus density estimates for your target size. Changing DPI metadata alone does not create extra pixels or add detail.
How print size is calculated
Divide pixel dimensions by the intended pixels per inch. For example, a 3000 × 2400 pixel image can produce a 10 × 8 inch print at 300 PPI, before cropping, margins, or printer-specific limits. This estimate is based on actual pixels, not just a DPI label stored in metadata.
| Effective resolution | Typical use |
|---|---|
| 300 PPI or higher | Detailed prints viewed up close |
| 240–299 PPI | Good resolution for many photo prints |
| 150–239 PPI | May suit larger prints viewed from farther away |
| Below 150 PPI | May look soft at the selected size |
These are practical guidelines, not universal rules. Viewing distance, printer, paper, sharpening, subject matter, and personal preference affect results. A large wall print can look good at a lower density than a small image viewed closely.
Why use an image DPI checker?
- Prepare photo prints: Estimate whether a photo has enough pixels for your chosen print size.
- Check posters and artwork: Review resolution before placing images into a design or print layout.
- Inspect downloaded files: See whether a JPG, PNG, or WebP contains standard resolution metadata.
- Compare several images: Check multiple files in one session and export the results to CSV.
- Avoid misleading DPI labels: Understand why changing metadata cannot restore missing image detail.
Supported formats and privacy
The checker supports JPG / JPEG, PNG, and WebP images that your browser can decode. It looks for common JPEG density and EXIF values, PNG physical-pixel metadata, and WebP EXIF resolution data. Some files contain no DPI metadata, and unusual or proprietary fields may not be recognized.
Processing runs locally in your browser and requires no paid API. Files larger than 10 MB and unsupported formats are rejected; up to 10 images can be checked at once. This tool does not compress, edit, re-encode, or download your source files.

After checking resolution, use the Image Compressor to reduce file size, the Image Metadata Remover to create a fresh sharing copy, or the Image Converters directory to find a format tool.
Frequently asked questions
How do I check the DPI of an image?
Choose a JPG, PNG, or WebP image. The tool reads pixel dimensions and checks for standard embedded resolution metadata, then calculates print size at 300 DPI and estimated density at your target print size.
Can I check DPI without uploading my image?
Yes. Selected files are processed locally in your browser. The tool does not send images to a PixxelConverter processing server or require a paid API.
What if DPI metadata is missing?
Some files do not store a standard DPI value. The tool says when it cannot detect recognized metadata and still calculates print size from the image's pixel dimensions.
Is 300 DPI always needed for printing?
No. Around 300 PPI is a common target for detailed prints viewed close up, but larger prints can look good at lower densities depending on viewing distance and print conditions.
Does changing DPI increase image quality?
No. Changing a DPI metadata number does not add pixels or recover missing detail. Effective print resolution depends on pixel dimensions and physical print size.
What is the difference between DPI and PPI?
DPI describes printer dots per inch, while PPI describes image pixels per inch. People often use them interchangeably; this checker displays metadata and calculated print density separately.
Which formats are supported?
This version checks JPG, JPEG, PNG, and WebP images up to 10 MB each, with up to 10 files per session.
Are my original images changed?
No. The checker only reads image dimensions and resolution metadata. It does not edit, re-encode, or compress the original file.
