About Annotate PDF
Annotate PDF is here for changing what is on the page: combine text, shapes, drawing and highlights in one session. It takes PDF and produces PDF. Nothing is sent anywhere: the browser reads the file, does the work and hands the result back.
The slow route to changing what is on the page is installing something, making an account and uploading the file; this is the fast route.

Annotate PDF: questions
- Is there a file size limit?
- A single file may be up to 100 MB, and a batch up to 50 files. Those are guardrails rather than a paid tier — the work happens on your machine, so an enormous document is limited by your own memory before it is limited by us.
- Is it safe to use for a document with personal details in it?
- That is the design goal: the document stays on your device, so a statement, a contract or an ID photo is never transmitted for processing. Nothing here needs an internet connection once the page has loaded, apart from engines that fetch their own model data.
- Will it work on a phone?
- Yes. The layout adapts to a small screen and the processing runs in the mobile browser, so a photo or a downloaded document can be handled on the device it arrived on.
- Is this free, or free until it asks for a card?
- Free, with no upsell behind it: no account to create and no file-count quota that appears halfway through a job.
