Frequently Asked Questions
Get answers to common questions about our image DPI checker and DPI converter tools.
DPI stands for "Dots Per Inch" - it measures the density of ink dots placed on paper when printing an image. Higher DPI means more dots per inch, resulting in sharper, more detailed prints.
PPI (Pixels Per Inch) refers to pixel density in digital images, while DPI (Dots Per Inch) refers to print resolution. Though often used interchangeably, PPI is more accurate for digital files. Our tool works with both to ensure optimal results.
Simply upload your image to our DPI checker tool. It will instantly analyze the file and display the current DPI resolution along with other metadata. All processing happens locally on your device for complete privacy.
Yes! Our DPI converter modifies the resolution metadata without re-encoding the image pixels, preserving the original quality. This changes how the image will print but doesn't alter the actual image data.
For high-quality photo printing, 300 DPI is the professional standard. For casual prints, 150 DPI may suffice. Our 300 DPI converter makes it easy to prepare images for professional printing.
No, changing DPI metadata doesn't affect the actual image quality or pixel data. It only changes the print size information. The visual quality depends on the original image resolution, camera settings, and editing processes.
For web display, 72-96 DPI is sufficient since screens display images in pixels, not print dots. Higher DPI for web images only increases file size without improving on-screen appearance.
Absolutely! Our batch processing feature allows you to convert multiple images simultaneously. Perfect for preparing image collections while maintaining consistent DPI settings across all files.
Yes, completely safe. All image processing happens locally in your browser - your images never leave your device. We don't upload, store, or have access to your files, ensuring 100% privacy.
Our tools support all major image formats including JPEG, PNG. The DPI converter maintains format compatibility while adjusting resolution settings for optimal print or web use.
This happens when the image's pixel dimensions are insufficient for the desired print size at high DPI. Use our converter to adjust DPI settings appropriately, or ensure your images have enough pixels for the intended print size.
Our tools combine local processing with intelligent metadata modification. Unlike competitors requiring uploads, everything works in your browser. This ensures privacy while delivering professional results with batch processing capabilities.
