Drop a print file and get the complete preflight report — every measurement a prepress operator would check. No arbitrary thresholds: add your own trim size, bleed and resolution below if you want them judged. Files are deleted after processing.
Optional — tune the checks to your product. Locked once files are submitted.

Filecheck does it automatically for every customer upload — on WooCommerce, Shopify, PrestaShop, OpenCart, or any site — before a bad file ever reaches your queue.
Drag your PDF into the checker. It is inspected cloud-side — nothing is installed and the file is auto-deleted after processing.
Every measurement a prepress operator would check: page boxes and bleed per edge, color spaces and ink coverage, fonts, effective image resolution, and document structure.
Filecheck auto-fixes what it can: adds bleed, converts RGB to CMYK, embeds fonts. Download the print-ready result and the report PDF — free, no signup.
A print-ready PDF has at least 3mm bleed on every edge, uses CMYK color, keeps images at 300 DPI effective resolution or higher, and embeds every font. This checker tests all of those in one pass and shows you exactly which rules pass or fail — free, with no signup.
Preflight inspects the file the way a prepress operator would before sending it to press: bleed and trim geometry, color spaces (RGB, CMYK, spot colors), effective image resolution at print size, font embedding, and text placed too close to the trim line (the safe zone).
Both. The report always shows every finding, and Filecheck auto-fixes what can be fixed safely: it can add bleed, convert RGB objects to CMYK, and embed missing fonts. Issues that need a design decision — like text sitting outside the safe zone — are flagged as warnings instead.
Paper shifts slightly when it is cut. Bleed extends your artwork past the trim line so that tiny cutting variations never leave a white sliver on the edge. 3mm is the common European standard; US printers usually ask for 0.125 inch, which is almost the same.
No. Files are processed cloud-side and automatically deleted after the check. Nothing is kept, shared, or used for anything other than producing your report and fixed file.
No. The check, the on-screen report, the report PDF download and the auto-fixed file download are all free — no account, no signup. There is a fair-use daily cap.
Validate a PDF against archival and accessibility standards — PDF/A-1b, 2b, 3b or PDF/UA — with every failed clause listed.
Convert screen-RGB artwork to press-ready CMYK with a real ICC profile — and see exactly how the colors will shift before you print.
Pad any product photo to a perfect square on a white background, strip EXIF data, and check it against marketplace listing rules.
Extend your artwork past the trim line with exactly the bleed your printer asks for — 3mm business card or 10mm banner — without reopening the design file.
Find the effective DPI of your image at the size YOU want to print it — a photo that is razor sharp as a postcard can be a blur as a poster.
