Processed entirely in your browser — nothing is uploadedWhy DPI matters for some forms
DPI (dots per inch) only really matters for print — a photo destined for a screen doesn't need a specific DPI value at all, but a few printing-focused application forms specifically ask for 200 or 300 DPI. If this checker shows no DPI value, or a low one, use our DPI converter to set the value your form requires.
How to use Check Image DPI
- Upload the file (or files) this tool needs.
- Let the tool process everything in your browser — this usually takes a few seconds.
- Check the result or information shown on screen.
- Download the output, or copy the information shown, depending on the tool.
Tips for best results
- Well-lit, high-resolution source photos give noticeably better results than dark or blurry ones.
- Process one file at a time first to check the settings before running a large batch.
- Keep your original files — most of these tools create a new file rather than modifying the one you uploaded.
❓ Frequently asked questions
Is my file kept or stored anywhere?
No — nothing is uploaded to a server; all processing happens locally on your device.
Can I use this tool more than once in a row?
Yes — there's no limit on how many times you can use it.
My file shows no DPI at all — is that a problem?
For on-screen use, no. Many web images and screenshots simply don't store a DPI tag. If a form specifically requires one, use our DPI converter to add it.
Does changing DPI affect image quality?
No — DPI is just a metadata tag describing an intended print scale; it doesn't change the actual pixel data or visual quality.
Does this work on PNG files?
This checker is built for JPEG's DPI field specifically; PNG uses a different metadata mechanism that isn't covered here.
