Documents

Combine several PDFs in the order you choose, or take only certain pages from each. Rename the result; contracts never leave your browser.

Extract pages into one file, or split into a file per N pages. Output names carry the page range, so a file sent on still makes sense. Nothing is uploaded.

Combine JPEG and PNG images into a single PDF, one image per page, on pages that match each image or on A4 and other fixed paper sizes.

Stamp page numbers on every page: six positions, three formats, a start value and a size you choose, and an option to skip the cover.

See a PDF's page count, each page's size and orientation, whether it is encrypted, its form fields and its metadata. Exports as text or JSON.

Add a text watermark to a PDF — Chinese and Japanese included. Tiled, centred, footer or a custom position, with adjustable angle and opacity.

Render each page of a PDF to an image at 96, 150 or 300 DPI. Zero-padded names keep page order, and you can export selected pages only.

Rotate PDF pages by 90°, 180° or 270°, all pages or a range. Two modes cover sideways scans and wrong rotation flags.

Delete pages from a PDF, put them in a new order, or duplicate one. Both fields use the original page numbers, applied delete-then-order.

List and export the files embedded inside a PDF, flagging executables and scripts. Read-only, nothing is executed, nothing is uploaded.

Pull embedded images out of a PDF: JPEGs byte-identical, Flate rebuilt as PNG, the rest reported. Several images are packed into one ZIP.

Find and remove duplicate pages in a PDF by comparing text content, keeping the first occurrence. The output lists every page removed.

Extract the text from a PDF as plain text, page by page, with an optional range. A per-page report shows each page and which pages have no text layer.

Change a PDF's title, author, subject and keywords, or clear all metadata including the producing software. Empty fields are never touched.

Read a PDF’s digital signatures — signer, time, reason, method — and compute which bytes the signature covers. Read-only, no verification.

Make every page A4, A3, Letter and so on, or keep the size and add margins. Proportional scaling, never stretched; landscape pages get landscape paper.

Renders every page to JPEG and rebuilds the PDF; scans often shrink by 70–90%. The trade-off: text becomes an image. Nothing is uploaded.

Lay Markdown or plain text out as a multi-page PDF with headings, lists, quotes and code blocks. CJK and emoji work; the text is not selectable.

Open a zip in the browser: list what is inside with sizes, pick the files you want and download them as a new zip. Everything is extracted locally.

Bundle several files into one ZIP, compressed or stored, with automatic name de-duplication. Nothing is uploaded — it all runs in your browser.

Parse an mbox archive: message count, date range, top senders and attachments. Decodes base64 and quoted-printable. Nothing is uploaded.

Inspect an EPUB: title, author, language, chapter order and titles, image list, and how much space text, images and fonts take. Supports EPUB 2 and 3.
