Check image pixels and aspect ratio, or PDF page count, dimensions and rotation. View file size in KB without uploading your file.
How to use
- Choose an image or PDF
- Run the checker
- Read dimensions and file size
- Compare the values with your form requirements
Practical example
A 1200 × 675 image has a ratio of about 1.778. A portrait A4 PDF page is about 210 × 297 mm. Rotated PDF pages also display their rotation value.
Privacy and file limits
The tool does not upload your files. Processing happens in this browser. Limit: 25 MB per file, 50 MB total and 30 files; decoded images up to 24 megapixels. Keep the original and review every output.
Troubleshooting
Choose a supported format and an unencrypted PDF. If memory runs low, use smaller files or fewer files. A low KB limit may be impossible at large dimensions. Do not use PDF edits for signed or interactive documents without checking the result.
