Filecheck does it automatically for every customer upload — on WooCommerce, Shopify, PrestaShop, OpenCart, or any site — before a bad file ever reaches your queue.
Drop an RGB image or PDF. The conversion runs cloud-side with a proper ICC profile — not a naive channel swap.
A side-by-side soft-proof shows your original next to the CMYK result, so you can see the color shift before anything goes to press.

RGB is emitted light and can show colors that ink on paper physically cannot reproduce — especially vivid blues, greens and oranges. A proper ICC conversion maps those out-of-gamut colors to their closest printable equivalent. Seeing the shift on screen first is exactly what the side-by-side proof is for.
Yes. The converter handles multi-page PDFs as well as PNG, JPEG and TIFF images, converting every RGB object in the file — images, vector fills and text colors alike.
Coated FOGRA39, the common European offset standard, with GRACoL available for US workflows. Using a real press profile is what makes the output predictable on paper instead of just "looking converted" on screen.
Yes. Naive conversions turn black text into a four-color "rich black" mix, which looks blurry in print if the plates are even slightly misregistered. This converter preserves true black as 100% K on the black plate only.
Photoshop can do ICC conversions if you pick the right profile, but Canva and most browser design tools only export RGB. And a mode switch alone says nothing about K-preservation or how a specific press will render the result. This tool does the conversion the way prepress software does, free, in the browser.
Yes — converting, the before/after proof and the download of the converted file are all free, with no signup and a daily fair-use cap.
The complete preflight report in seconds — geometry, color, ink, fonts, images and structure. Optionally check against your own trim size, bleed and resolution.
Validate a PDF against archival and accessibility standards — PDF/A-1b, 2b, 3b or PDF/UA — with every failed clause listed.
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.
