Add text, your signature, pictures, highlights and shapes to a PDF, fill in its form fields, and rotate, reorder or delete pages, then download the edited PDF. The text already in the PDF can’t be changed, and the file never leaves your device.
PDF editor
Choose a PDF to begin.
Enter the password to open it. The edited copy is saved with the same password.
Nothing added yet — pick a tool.
Open the PDF in the editor above and pick a tool: Text to add text to PDF pages, Sign for your signature, or Image, Shapes, Pen, Cover, ✓ ✗ and Date. Click the page where text, a shape, a tick or the date belongs; a picture or a signature appears in the middle of the page for you to drag into place. Click a form’s own fields to fill them in, and use Pages to turn, move or delete pages. Then press Download edited PDF — free, with no account, no watermark and no upload.
Press Add text, then click anywhere on a page and type: a name, an amount, a note in the margin. It is how you write on PDF forms that have no fields of their own. Choose from five fonts — sans, serif and monospace, plus Vazirmatn and Noto Naskh Arabic for Persian and Arabic — a size, and black, blue or red; one text box holds up to 2,000 characters. Date writes today’s date, and ✓ and ✗ put a tick or a cross where you click.
Press Sign and draw your signature with a finger, a mouse or a pen, type your name in a handwriting style, or use a picture of your signature. What lands on the page is a picture of your signature, like ink on paper — not a digital signature. It carries no certificate and does not prove who signed; if a form asks for a digital signature, use the signing service the form names. Nothing is stored between visits: keep a picture of your signature to use it again.
When a PDF has form fields, click them to type, tick check boxes, pick radio buttons or choose from dropdowns and lists. Your answers go into the form’s own fields, so the download is still a working form. Fill a flat form without fields with Text, ✓ and Date. Forms built only with XFA cannot be filled in here; the editor tells you when you open one.
Image adds a JPG, PNG, WebP or HEIC picture — a stamp, a logo, a photo — up to 40 megapixels and 50 MB. Shapes draws rectangles, ellipses, lines and arrows in several line widths and fills. Pen draws freehand, and as a highlighter it marks text in yellow, green, pink or blue.
Open Pages to turn the current page 90°, move it up or down (or drag its thumbnail), delete it, add a blank page after it, or add the pages of another PDF — a quick way to put two files together. Deleted pages are removed from the downloaded copy, not just hidden: the file is written anew without them.
Cover draws a plain box over part of a page, in the page’s own colour or white, so it no longer shows on screen or on paper. It only hides: what is under the box stays in the file and can still be copied, found by search or uncovered. Do not use it to keep private information out of a document.
Right-to-left text is joined and ordered correctly — Persian and Arabic in their own fonts, Urdu in a Naskh-style font — and numbers and English words inside a sentence keep their order. With Vazirmatn and Noto Naskh Arabic built in, a Persian or Arabic line on an English document looks the same in every PDF reader. The editor also has its own Persian page.
Most online PDF editors upload your file to their server first. This PDF editor works inside your browser: the PDF is opened, edited and saved on your own phone or computer and is never sent to LensUp or anyone else — so there is no server copy to worry about, and nothing to delete afterwards. While you type, the editor downloads the pieces of font your text needs; your document itself goes nowhere.
It is made to add text to PDF pages, along with signatures, pictures and marks, and to fix their order — not to rewrite what is already there. Know these limits before you start:
Yes. There is no account to create, no watermark on the download and no daily or hourly limit. The limits are per file: up to 100 MB and 200 additions, and adding pages stops at 1,000 pages.
No. The PDF is opened, edited and saved in your browser and is never sent to a server. While you type, the editor downloads the pieces of font your text needs; your PDF stays on your device.
No. This editor cannot change or delete the existing text. To replace a word, put a Cover box over it and type the new text on top. Cover only hides: the old text stays in the file and can still be copied or found by search.
Yes. You can edit PDF online in current Chrome, Safari, Firefox and Edge on phones, tablets and computers, and on a phone the editor has its own tool bar. There is no app to install.
Yes. Press Sign, then draw your signature, type your name in a handwriting style or use a picture of your signature, and drag it into place. It is a picture of your signature, not a digital signature: it carries no certificate and does not prove who signed.
Yes. Click a field to type, tick a check box, pick a radio button or choose from a dropdown or list; your answers are saved in the form’s own fields, so the file stays a working form. Forms built only with XFA cannot be filled in here.
You can add text, a signature, ticks, pictures and highlights on top of a scan, and turn, move or delete its pages. The editor does not recognise the words in a scan (no OCR), so the scanned text itself cannot be changed.
Yes. Open Pages to turn the current page 90°, move it up or down or drag its thumbnail, delete it, add a blank page after it or add the pages of another PDF. Deleted pages are gone from the downloaded file.
PDFs up to 100 MB; adding pages stops when a document reaches 1,000 pages. A password-protected PDF opens with its password and is saved with the same one; a PDF locked only against changes (no password asked when it opens) opens too, and the download does not keep those restrictions. Pictures you add can be JPG, PNG, WebP or HEIC, up to 40 megapixels and 50 MB.
Most online PDF editors upload your file to their server; some also ask you to sign in before you can download, or limit how many files you can edit per hour or per day. This PDF editor keeps the file on your device, with no account and no daily limit. Many other editors can change existing text or read scanned text with OCR; this one cannot.
Yes. Added text is drawn into the page as outlines, so every reader shows the same letters in the same place, and it prints the same way. The trade-off: PDF readers cannot select, copy or search that text.
Cover puts a plain box over it, in the page’s own colour or white, so it no longer shows on screen or on paper. It only hides: the text or picture under the box stays in the file and can still be copied, found by search or uncovered, so do not use it to keep something secret.
