The checks that catch most rejections
Print files fail for boring reasons far more often than exotic ones. A merged document with three page sizes. A flyer exported at the trim size with zero bleed. A password someone forgot to remove. This tool reads the PDF’s geometry (boxes, sizes, rotation, encryption) and flags exactly those, in seconds, before the printer’s queue does it overnight.
Honest scope
This is a structural preflight, and structure is not everything. What it verifies: page-size consistency, TrimBox presence, bleed margins, rotation flags, encryption, standard-size match. What it deliberately does not verify: color spaces, ink coverage, font embedding, image resolution, and overprint. Those live in the content stream and need a full preflight engine like Acrobat Pro’s. Run this first; if it passes and your printer still wants a full PDF/X check, that’s the tool they mean.
Fixing what it finds
| Finding | Fix |
|---|---|
| No bleed | Re-export at trim + bleed. The bleed calculator gives exact targets |
| No TrimBox | Enable printer’s marks / bleed settings in the export dialog |
| Mixed page sizes | Rebuild from one source at one size; check pages in the page size checker |
| Password protection | Re-save without security from any PDF viewer |
| Nonstandard size | Confirm against the product spec. Custom sizes are often intentional |
If the file needs rebuilding rather than re-exporting, the PDF to JSON converter opens it as an editable design where sizes and bleed can be set properly before a clean export.
