Compare two revisions of a PDF, side by side.
Drop the older and newer documents above, then hit Compare. Pages are paired side by side with synchronised scrolling — where one document has extra content the other side waits, so matching sections stay level. Hover over text to outline the matching sentence or table cell on the other side; hovering a highlighted change outlines the corresponding changed text instead. Use n/p to jump between changes, h to toggle highlights, and Ctrl+scroll (or +/−) to zoom.

Page numbers print small and neat in the margin — pick the corner, the style and where
counting starts. Bates numbers print a unique padded identifier on every page
(e.g. ABC-000041), the standard for legal and contract document sets. Watermark prints
a large label — DRAFT, SUPERSEDED, FOR INFORMATION — across every page. Tick any combination,
then Stamp & download. The original file is untouched; stamps are drawn into a copy, and
text underneath stays selectable and searchable.
Touch-up edits, not re-typesetting. Click a line of text and retype it — the original
is covered and your text is drawn in a matching font, size and colour. PDFs carry no
paragraphs, so a longer line never re-wraps the lines below; this tab is for fixing a typo,
a date, a name or a number, adding a label, or blanking something out. Add text drops
a new text box anywhere (drag to move it); Whiteout covers a region with the
surrounding background colour; Image places a picture — a signature, a logo — which
you can also paste straight in with Ctrl+V or drag onto the page as a file (drag to move it,
corner handle to resize). Edits stay pending while you move between pages — nothing is
written until Download edited PDF, and the original file is untouched. Scanned pages
carry no selectable text: run Convert → “Scan → searchable (OCR)” on
the file first, or use Add text and Whiteout directly. If the document carries a digital
signature, any edit invalidates it.
Smaller images re-compresses the photos and figures embedded in the file —
oversized ones are downscaled and everything is re-encoded as quality JPEG — while the
pages themselves are never rasterised: text stays selectable, searchable and comparable.
This is usually where huge report files shrink the most.
Lossless clean-up rewrites the file with compressed object streams and drops unused objects and stale incremental-save data. Text stays selectable and nothing is re-encoded, so savings are modest unless the file carries dead weight.
The JPEG presets re-render every page as a photo at the chosen detail — this is where huge files (scans, image-heavy reports) shrink dramatically. The trade-off: text in the output is a picture, so it can't be selected or searched, and such pages can't be text-compared later. 200 dpi still prints crisply; 110 dpi is for email-sized copies. If the result wouldn't be smaller than the original, nothing is downloaded.
