Edit, annotate, sign and organize your PDF directly in your browser.
This is a browser-based PDF editor built for people who need to make quick, reliable edits to a document without installing desktop software or handing a file over to a stranger's server. Open a PDF, add text or a signature, mark it up with highlights and shapes, reorder or remove pages, then download the result — all inside this tab.
Students filling out and annotating assignment PDFs, job seekers tweaking a resume, small business owners editing invoices and contracts, teachers marking up worksheets, and anyone who just needs to quickly sign, highlight or fix a page in a PDF without downloading desktop software.
No. This editor renders your PDF with PDF.js and applies edits with pdf-lib, both running as JavaScript inside your own browser tab. The file is read from your device into memory, edited there, and the download is generated locally — it is never transmitted to a server as part of the editing process. If you separately choose to enable local recovery, a temporary copy may be kept in your browser's own storage (IndexedDB) purely so you can recover unsaved work after a crash; you can clear it any time from the More menu.
Standard, multi-page, text-heavy, image-heavy and scanned PDFs are supported, including large documents rendered a few pages at a time for performance. Password-protected PDFs can be opened once you provide the password. For text replacement, the editor detects the nearest standard font family, font size, bold/italic styling, and samples foreground and background colours from the rendered page. It then carries that style into newly added text. Exact reproduction of unusual subset-embedded or licensed custom fonts is not always possible in a browser. Very unusual or malformed PDFs may not render perfectly; the editor reports the problem instead of failing silently.
No. Your PDF is opened and edited locally inside your browser using PDF.js and pdf-lib. The file never leaves your device during editing.
Yes. Opening, editing, annotating, merging, splitting and downloading your PDF is free, with no account required.
Yes, through cover-and-replace editing. The editor detects the closest standard font, original size, bold/italic style, and sampled text/background colours. Unusual subset-embedded custom fonts may use the closest available match.
You'll be asked for the password locally in your browser. It's used only to open the file in memory and is never sent anywhere.
Recommended up to 100 MB. Larger files may work depending on your device's available memory — the editor will tell you if a file is too large to process safely rather than freezing.
No installation needed. The editor runs entirely inside your web browser, so it works the same way on Windows, Mac, Linux and Chromebooks.
Yes, the editor is responsive and works on mobile browsers, though larger PDFs are easier to edit on a bigger screen.
No watermark is added to your downloaded PDF.
