Prepta
Check a file

Free tools for print-ready files

Check customer artwork before it reaches production. Every tool runs the same free preflight engine — and routes into Prepta when you want automatic repair.

  • Full preflight

    PDF preflight checker

    Upload a PDF and check bleed, trim, colour spaces, fonts, resolution, transparency and PDF/X markers against a real production profile. Free Prepta Score, no account.

  • Any file format

    Print file checker

    A print job rarely starts as a tidy PDF. Drop a JPG, PNG, TIFF, an iPhone HEIC photo, a Photoshop, Illustrator or EPS file, or a PDF, and we check it against a real production profile. Formats the press cannot take directly are converted to a working copy first, then checked.

    PDF bleed checker

    Missing or unverifiable bleed is one of the most common reasons print shops send files back. Drop a PDF here and we measure bleed against a production profile. Colour, fonts and the rest of the public preflight run at the same time.

    PDF CMYK checker

    RGB files look fine on screen and surprise you on press. This free check measures colour spaces against a CMYK production profile and returns a clear Prepta Score with every finding.

    PDF resolution checker

    Low-resolution images are a classic reprint cause. Upload a PDF and we check placed-image resolution against a production profile, along with everything else in the public preflight.

    PDF/X checker

    Many RIPs and print portals expect PDF/X identification. This free check looks for the PDF/X-4 markers our public profile requires, and says plainly that it is a marker check rather than a full ISO PDF/X validation suite.

    PDF font checker

    An unembedded font can stop a job or silently substitute on the RIP. Drop a PDF here and we check font embedding against a production profile. Colour, bleed and the other public checks run alongside it.

    PDF transparency checker

    Live transparency and blend modes look fine on screen and fail on some cutters, older RIPs, or spot-colour workflows. This free check flags transparency against a production profile, and runs the rest of the public preflight in the same pass.
