What Image DPI Checker & Converter does
Check image resolution and print size, then update DPI metadata or resample the pixels. The tool keeps the operation focused and creates a separate result so the original remains available for comparison.
Image DPI Checker & Converter processes the supplied input in the browser unless its interface explicitly identifies a browser-managed service.
How to use Image DPI Checker & Converter
Set up Image DPI Checker & Converter around the final use case rather than an arbitrary maximum. Test the workflow on non-critical material before processing an important source.
- Select a source image and inspect its format, pixel dimensions, orientation, and transparency before making changes.
- Choose the crop, size, format, quality, color, metadata, or visual setting required by the destination.
- Use the preview at both fit-to-screen and full-size views to check edges, text, color, and artifacts.
- Download the result, reopen it independently, and confirm its pixel dimensions, format, transparency, and file size.
Where Image DPI Checker & Converter fits
Use the calculator to translate pixel dimensions into a physical print size before sending artwork to a printer, publisher, or document workflow. A metadata-only update is appropriate when the pixels are already sufficient and only the intended scale is missing; resample only when the destination truly requires new pixel dimensions, and compare sharpness at the final physical size.
Use Image Resizer for exact screen pixel dimensions, or Image Upscaler when enlargement and sharpening controls matter more than print-resolution metadata.
What to check
Check pixel dimensions, embedded resolution, calculated physical size, units, aspect ratio, and export format. Distinguish a metadata-only scale change from a true resample before sending the image to a printer or publisher.
Check pixel dimensions, crop boundaries, transparency, small text, color, and the downloaded format at 100% zoom. Re-encoding may intentionally remove metadata and can change compression artifacts.
Privacy and limitations
Resolution inspection, metadata updates, pixel resampling, and export run in the browser. The selected image is not uploaded to PagesTools.
Changing resolution metadata alone does not add pixels or improve detail. Resampling can change pixel dimensions and file size but cannot recover detail absent from the source; printers and publishing applications may also override embedded DPI metadata.
