Make the file fit.
19 tools for the PDF that is 3 MB too big, the .docx a portal will not take, the scan that came out sideways. Every one of them runs in this tab — your file is never uploaded.

Questions
- Are my files uploaded anywhere?
- No. The conversion runs in your browser using JavaScript and WebAssembly — the file is read into this tab’s memory and written back out there. The site is served as static files from Cloudflare’s edge and has no upload endpoint, no database and no server-side processing. The page ships a Content Security Policy that forbids it from contacting any host other than its own origin, so this is enforced by your browser rather than promised by us.
- Is OfficeTool free, and is there a catch?
- Yes, completely, with no account, no watermark on the output, no daily limit and no paid tier. Because your device does the work, running this costs us nothing but hosting a few static files. There is no advertising and no analytics or tracking of any kind.
- Is there a file size limit?
- There is no limit imposed by a server, because no file reaches one. The real constraint is your device’s memory: a laptop handles a few hundred megabytes comfortably, a phone considerably less. When a file is too large the tool says so instead of failing silently, and usually suggests a lower resolution or splitting the document first.
- Does it work offline?
- Yes. Once the page has loaded, the tools keep working with no network connection — you can put your device into airplane mode and convert a document. That is a side effect of doing the work locally rather than a feature bolted on.
- Can it read scanned documents?
- It can compress, rotate, merge, split and convert them to images, because those operations work on the page as a whole. It cannot recover their words: a scan holds a photograph of text, and extracting text from a picture needs OCR, which this site does not do. Every text-recovery tool here detects a scan and tells you, rather than returning an empty file.
- Do I need to install anything or sign up?
- No. There is no account, no extension and no desktop program — it is a web page. Nothing is remembered between visits, and closing the tab leaves no copy of your file anywhere.
