Convert Word & Office files to PDF, turn images into a PDF, and merge or split PDFs.
Merge several PDFs into one, split a document into separate files, extract a page range, rotate pages, and convert images or Office documents to PDF. Everything except the Office conversion runs entirely in your browser.
Combining documents preserves each page exactly as it was — text stays selectable, vector graphics stay sharp, and nothing is re-rendered or re-compressed. Order matters and is taken from the order you add the files, so add them in the sequence you want them to appear.
A merged file is roughly the sum of its inputs, sometimes slightly smaller where fonts embedded in several source documents can be shared. If a merged file is unexpectedly large, the usual culprit is a scanned document, where each page is a full-resolution image rather than text.
Splitting produces one file per page; extracting pulls out a range as a single document. Both are useful when a form asks for one section of a longer report, or when a scanner has produced a single file from a stack of unrelated documents.
Page numbers here refer to the physical order in the file, which is not always the number printed on the page — front matter and cover pages routinely offset the two. Check the position of a page in your viewer before extracting by number.
Pages scanned sideways or upside down can be rotated in 90 degree steps. Rotation sets a flag in the page's metadata rather than re-rendering the content, so there is no quality loss and the operation is fully reversible. Some older viewers ignore the rotation flag and display the original orientation, which is worth checking if the recipient reports the page still appearing sideways.
Useful for submitting photographed documents where a portal accepts only PDF. A few practical points: photograph the document straight on and in even light rather than at an angle; crop out the surrounding desk before converting; and check the result is legible at 100% zoom before submitting, since a photo that looks fine on a phone screen is often unreadable when printed.
This is the one feature that uploads your file. Converting Word, PowerPoint, Excel, ODF, RTF, TXT or CSV documents requires a full office rendering engine, which cannot run in a browser. Your document is sent over HTTPS, converted by a headless LibreOffice process, returned to you, and the temporary copy is deleted as soon as the download finishes — deletion is wired into the request lifecycle rather than a scheduled cleanup.
The limit is 25 MB. If a document is confidential enough that a few seconds on a third-party server is unacceptable, use the export-to-PDF function in your own word processor instead. Every other tool on this page never receives your file at all. This distinction is set out in full in our privacy policy.
One caveat on fidelity: conversion renders with the fonts available on the server. A document using an unusual font may reflow, shifting page breaks. Check the output before relying on it for anything paginated.
Large PDFs are almost always large because of images. A text-only document of fifty pages is typically under a megabyte; a scanned one can be fifty times that. The effective fix is to compress the images before they go into the PDF — our image compressor handles that — or to scan at 200-300 DPI rather than 600, which is more than sufficient for document text.
Merging, splitting, extracting, rotating and image-to-PDF conversion all run locally using the pdf-lib library loaded into the page. Your documents are not uploaded for any of these operations, so there is no queue, no server-imposed size limit beyond your device's memory, and no copy retained anywhere. You can verify this in your browser's Network tab — only the Office conversion produces a request.
Not for merging, splitting, extracting, rotating or image conversion — those run entirely in your browser. The single exception is converting Word and other Office documents, which requires a server-side rendering engine; that file is deleted the moment your download completes.
No. Pages are copied as they are, so text stays selectable and vector graphics stay sharp. Nothing is re-rendered or re-compressed.
No. PDF describes glyph positions rather than editable paragraphs, so genuine text editing requires reflowing the page and dedicated software. These tools rearrange and combine pages rather than changing their contents.
Almost certainly images, particularly if it came from a scanner. Scanning at 200-300 DPI instead of 600, or compressing images before building the PDF, makes far more difference than anything else.
No. Encrypted documents cannot be processed without the password, and these tools do not strip protection from files.
