browser-based PDF utilities · updated 10 May 2026

A growing collection of browser-based PDF tools for the awkward parts of the job — splitting, merging, watermarking, rotating, extracting pages, editing metadata, and converting to and from images and text. Every tool runs entirely in your browser. Drop multiple files at once: every tool is batch-mode by default.

Stitching files together

Drop a folder of receipts and the merge tool stacks them into a single PDF in the order you put them. Re-arrange the queue with the up/down buttons before merging if the alphabetical sort isn't what you want. The split tool goes the other way — chop a 200-page report into one PDF per page, into N-page chunks, or into named ranges (e.g. 1-3, 5, 9-12). Multiple input PDFs at once produce a ZIP per input file.

Pages, in any order

Extract pages grabs a subset (1,3-5,8) into a fresh PDF. Reorder / delete rebuilds the document with only the pages you list, in the order you list them — handy for removing a duplicate cover page or moving an appendix to the end. The rotate tool turns selected pages by 90°, 180°, or 270° without re-rendering anything else.

Branding and bookkeeping

The watermark tool stamps centered or corner text (DRAFT, CONFIDENTIAL, your name) over every page with adjustable opacity, rotation, and font size — applied across every file in the batch. Page numbers adds Page 3 of 24 style numbering with a configurable position, format, and start offset. Edit metadata sets or strips the title, author, subject, and keywords on every PDF you drop — useful before sharing, or after a converter has left a misleading author field.

Out of and into PDF

PDF → Images rasterises every page to PNG or JPG at the DPI you choose, packed in a ZIP per source file. Images → PDF goes the other way — drop a stack of photos or scans, pick page size and margin, get a single multi-page PDF (or one PDF per image). PDF → Text and PDF → Markdown pull the underlying text out — the markdown variant infers headings from font-size jumps, which is a useful starting point for getting a long PDF into a wiki. HTML → PDF rasterises pasted HTML or dropped .html files into a printable PDF.

What they have in common

Everything runs in your browser. The PDFs you drop or paste never leave your machine — there is no server component handling data. I can't see your files because they were never sent to me. That means no upload size cap beyond your browser's memory (typically 500 MB to 1 GB per file on a laptop), no account required, and nothing for me to leak. See the privacy policy for the longer version.

Batch mode by default. Every tool accepts more than one PDF at a time and processes them sequentially. The output is one downloadable file per input, so you can drop a folder of statements, run watermark or page-numbers, and get a folder of stamped statements back without scripting anything.

Free to use, with no warranty. Read the terms of use before relying on the output for anything load-bearing. Bug reports, corrections, and feature requests are always welcome — drop me a line.
