Local file and layout tools
Print preparation workspace
Check observable file dimensions, plan physical output, and keep a reusable record without uploading your image or PDF. Each result is a transparent inspection or layout—not a promise that a printer will accept the file.
Image to print
Check effective PPI and physical size
Read an image’s real pixel dimensions locally, then choose the intended print size.
Choose an image to read its pixel width and height. Nothing is uploaded.
REUSABLE JOB
Save these settings
The browser copy stays on this device. It can be cleared, so export the file when you need a backup.
PDF page boxes
Inspect observable page-size metadata
See page, crop, trim, bleed, and art boxes that are directly detectable in the file.
This does not certify a PDF as press-ready, PDF/X-compliant, correctly imposed, or acceptable to a specific printer. It does not inspect fonts, color spaces, image resolution, transparency, overprint, or printer-specific requirements.
Booklet page order
Plan a simple saddle-stitched booklet
Calculate conceptual two-sided sheet order without changing or uploading your PDF.
16 imposed pages · 4 sheets · 0 blank pages added
This is a mathematical page-order plan for a complete-document saddle stitch. Printer duplex orientation, creep, trim, binding, blank placement, signatures, and the print provider’s workflow still need separate confirmation.
Local contact sheet
Arrange a printable image reference sheet
Preview up to 24 local images in a simple grid. The selected files stay in this browser session.
Choose images to build the contact sheet.
Browser print scaling and printer margins can change the physical result. Use the print dialog’s preview, choose the intended paper, and verify critical dimensions with a ruler.
Formula
What the calculator does
Image PPI equals pixels divided by the planned physical dimension. PDF points convert at 72 points per inch. Saddle-stitch page order pairs the first and last pages of a document on the same folded sheet, padding to a multiple of four when needed.
Keep the result honest
- Uploaded images and PDFs are read in your browser and are not stored with the saved job.
- The PDF report lists only metadata this bounded inspector can directly detect.
- Always confirm bleed, trim, duplex orientation, scaling, color, fonts, and file requirements with the selected printer.

Definitions and methods behind the result
Defines PDF user space and page boundary boxes. The local inspector reports observable box values without certifying the rest of the file.
