Impose existing PDF pages into vector-preserving booklet spreads with front/back ordering and automatic blank pages.
LOCAL FILE CONVERSION
Open a PDF as a cover, a natural reading book or a print-ready saddle-stitch booklet. Native PDF text and images stay sharp.
PDF up to 25 MiB / 200 pages · Browser only; no uploadCover first, then 2–3, 4–5 and so on. A final unpaired page stays alone. Facing-page exports use double-width PDF spreads; mobile preview shows one leaf at a time.
Reading mode uses natural page order, without print imposition or blank padding. Print mode retains saddle-stitch padding and duplex settings. Original visible page proportions, native text/fonts, paths and image bytes are preserved through PDF embedding; artwork is never stretched or rasterized for export. Book modes require unsigned/static pages; flatten supported forms/annotations first. Existing 25 MiB / 200-source-page limits apply; exports are limited to 64 MiB. Reading exports may contain up to 200 single pages; print exports remain at most 100 sides.
All processing stays in your browser. Preview rendering is bounded to 8 MP and loads one output page at a time. Reset/unmount cancels workers and releases PDF resources, preview images and download URLs. Paper shadows/spine are viewer decoration, not added to the PDF. Printer-driver scaling and paper feeding cannot be overridden.

Choose a supported local source using the upload area, review content and settings, generate the result, inspect actual previews and warnings, then download.
Impose existing PDF pages into vector-preserving booklet spreads with front/back ordering and automatic blank pages. Choose landscape A4/Letter sheets, margins, binding direction and duplex flip. Default short-edge mode uses booklet front/back order; long-edge mode rotates back content 180 degrees.
No. Source files, filenames and document content remain in browser memory, outside conversion APIs, storage and content analytics. Processing Workers are disposable and bounded. Reset/unmount cancels pending work and revokes owned preview URLs; ordinary page requests may still be logged.
Static PDFs of 1–200 pages are supported. Flatten forms and supported annotations first. XFA and signatures are rejected rather than silently losing interactivity or validity.
Choose landscape A4/Letter sheets, margins, binding direction and duplex flip. Default short-edge mode uses booklet front/back order; long-edge mode rotates back content 180 degrees.
Native page content, crop boxes, quarter-turn rotations and proportions are retained. Blank pages pad to a multiple of four. Check spread order and print a test sheet at actual size for your printer.
Static PDFs only: forms/annotations must be flattened first. Original cropped page content, quarter-turn rotation and aspect ratio are retained without page rasterization. Page count pads to a multiple of four. Default print workflow is landscape, actual size and duplex short-edge; long-edge mode rotates back-spread content 180 degrees. Printer driver behavior can vary, so inspect the imposed preview/test sheet. A4/Letter sheet sizes and margins are supported.

Inspect the actual exported PDF preview, page count, text, page breaks, images and any warnings. First/last representative pages are rendered automatically; use the output-page selector to check other pages. Download is an explicit action and reset discards the result.

Start with the original source file. Review detected content and choose the settings for your intended output. Inspect the actual generated preview and the reported page or image dimensions. Check all relevant pages, supported-object warnings, text, colors and transparency before downloading.
