Make a PDF print-ready — PDF/X-4 preflight, bleed and crop marks, on your device
Preflight the way a print shop does, then write the output intent, boxes, bleed and marks.
PDF/X for print now — free →Printers reject files for the same handful of reasons: fonts not embedded, no trim box, no output intent, missing identification, stray JavaScript. Bindery runs that preflight locally and shows every objection in plain language. Conversion writes an sRGB output intent with an embedded ICC profile, the PDF/X-4 identification in Info and XMP, the Trapped key, trim, bleed and art boxes on every page, and — if you ask — a bleed margin with crop marks.
PDF/X-4 permits RGB and transparency, which is what a browser can honestly guarantee; a CMYK-only PDF/X-1a needs colour conversion in the print workflow, and the report says so. Pages set in non-embedded fonts can be rasterised at 300 DPI so the file passes. Bindery runs entirely in your browser — your file is never uploaded, so there is nothing to delete from a server afterwards.
How it works
- Drop the PDF and open PDF/X for print — the preflight runs immediately
- Choose the bleed (none, 3 or 5 mm), crop marks and a document title
- Prepare for print and download the file with its preflight report
Questions people ask
Is this a certified PDF/X validator?
No. It is a thorough self-check that fixes what it can; your printer’s preflight has the last word, and the report lists every check so you can compare.
Does it convert colours to CMYK?
No. PDF/X-4 allows RGB with an ICC output intent, which Bindery declares. Press-profile colour conversion belongs in the print workflow.
What happens to fonts that are not embedded?
Those pages can be rasterised to a 300 DPI image so every glyph is guaranteed; their text stops being selectable. Leave the option off to keep the text and let the printer substitute.
