Free PDF Toolkit, in Your Browser
A growing toolkit of free PDF utilities — every operation runs entirely in your browser tab. Your files are never uploaded; there is no server component touching your data, no file-size cap beyond your browser's memory, and no account to sign up for. Pick a tool below, drop your PDFs, and go.
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 pages
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.
Delete pages is the quick path when you only want a
few pages gone, and N-up imposition combines 2, 4, or 6
source pages onto each output sheet for printing.
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.
Sign PDF stamps a signature image at a fixed position;
Redact PDF draws opaque blocks over sensitive regions
before you share.
Shrink, crop, resize, flatten
Compress re-saves with object streams and strips metadata to take the easy bytes off. Crop trims margins and sets the displayed page box (no re-render). Resize shifts pages between standard sizes (A4 / Letter / Legal / A3) or scales by a percentage. Flatten re-rasterises each page so form fields, comments, and overlays are baked into the image — useful before sharing a "final" version.
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.
PDF → Text
and PDF → Markdown
pull the underlying text out — the markdown variant infers headings from font-size jumps.
HTML → PDF
rasterises pasted HTML or dropped .html files into a printable PDF.
For scanned PDFs with no text layer, OCR PDF runs
Tesseract entirely in-browser.
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.
