If you have ever stopped halfway through uploading a contract to a free PDF site and thought better of it, this is built for that moment. It does the same jobs and never sends the file anywhere, because there is nowhere for it to be sent.
Edit, split, compress and annotate PDFs with no upload, no account and no server. Works with the network off once the page has loaded. Free, in the browser.
Open the editorFree, no account, and the file stays on your machine.
There is no API and no server component. The document is read with File.arrayBuffer(), parsed by pdf.js inside a worker, rewritten by pdf-lib, and handed back to you as a download. The pieces that normally reach out — the pdf.js worker script, its CMap tables and the standard font data — are copied into the app at build time rather than pulled from a CDN, so no part of handling a PDF involves a request.
That has a consequence you can test in about five seconds: load the page, disconnect, and keep working. Splitting, compressing, annotating, redacting and extracting all still function with no network at all.
An uploaded file is a copy you no longer control. It sits in someone's storage under a retention policy you did not read, gets backed up, and occasionally gets indexed — free PDF converters have leaked user documents into public search results more than once. For a holiday itinerary that is a shrug. For an employment contract, a passport scan, an NDA or a patient letter, it is the wrong default.
There is also the plain practical case: no upload means no waiting for one, no size cap imposed by a free tier, and no daily limit. A 150 MB scan is handled at the speed of your own machine.
Read and search, with real text selection. Reorder, rotate, duplicate, delete and merge pages. Split by range, by count or by selection. Compress, either by rebuilding the file losslessly or by rasterising it at a DPI you pick. Annotate with text, pen, highlighter, shapes and images. Redact so the covered content is destroyed rather than hidden. And pull out the text, images, vector artwork and embedded fonts as real files.
No. It is a web page. There is nothing to install, no extension and no account.
Once the page has loaded, yes, for every document operation. Only the interface font and — if you choose one — a Google typeface for the text tool would want the network, and both fall back cleanly.
Because it costs almost nothing to run. Your machine does the work; the host only serves static files. There is a donation button and that is the entire model.
Nowhere. It is held in memory for as long as the tab is open and is gone when you close it. Nothing is written to local storage except your light or dark theme preference.
That is the case it is designed for, and unlike an upload-based tool there is no third party to clear. Your own IT policy is still yours to check, but no data leaves the browser.
