Check a PDF for the reasons a print shop actually rejects a file — unembedded fonts, mixed page sizes, RGB images and low-resolution photos. Nothing is uploaded, and nothing is changed.
Drop your file here, or browse files
Read-only: this checks the file and reports what it finds. Nothing is changed, and nothing is uploaded — it downloads nothing either, because there is nothing to download.
Reorder, delete and merge PDF pages — or split every page into its own file. Nothing is uploaded.
Turn photos, screenshots or scans into a single PDF, at the page size and margin you choose.
Turn pages the right way up and trim their margins — on every page, or only the ones you name.
Make a PDF smaller in your browser — losslessly, by recompressing the photos already inside it, or by flattening pages to images when you need a much smaller file.
