PDF Editor Online Free
Edit and sign any PDF online, free and without login. Add text, annotations, shapes and a typed or drawn signature, then download a new copy — the document is never uploaded.
What can this free PDF editor do?
The editor opens any PDF right in your browser and lets you write on it: add text in any language and size, draw freehand, highlight passages, drop boxes and arrows, white-out content you want gone, and place a typed or hand-drawn signature. When you download, every annotation is flattened permanently into the file — with 0 uploads, because the whole editor runs on your device.
Editor tools at a glance
- Text — click anywhere and type; choose font family, size in points, colour and bold. Works in Hindi, Arabic and every other language.
- Sign — type your name in a script style or draw your signature, then tap to place it.
- Erase / white-out — drag a box over anything you want covered; combine with Text to replace content.
- Pen, Highlighter, Box, Arrow — annotate, mark up and point things out, with colour and thickness controls.
- Undo, Print, Download — step back mistakes, print the annotated document, or save the final PDF.
How do I fill and sign a form?
- Open the form PDF in the editor.
- Use the Text tool to type into each field (adjust size to fit the boxes).
- Create your signature with the Sign tool and tap the signature line.
- Click Download PDF — your filled, signed copy is saved to your device.
Is it safe to edit a contract or ID document here?
Yes. The editor renders pages with Mozilla’s PDF.js — the engine inside Firefox — and flattens your annotations locally on save. Because there is no upload step at any point, sensitive agreements, forms and identity documents remain solely on your device from open to download.
What changes the original PDF content?
The Text, Pen, Highlight, Box, Arrow, Erase and Sign controls create a visible layer over the rendered page. When you download, LyfPDF flattens that layer into the output so it appears in ordinary PDF readers and in print. This is ideal for filling a form, annotating a page or covering and replacing a short label. It does not reflow the source paragraph, recover the original font, or turn a scanned page into editable source text.
White-out is a cover, not confidential-data redaction. If information must be permanently removed before sharing, use Redact PDF, then reopen the result and search for the removed terms. If the PDF is a scan and you need selectable text, use OCR PDF first and compare the recognized text with the page image.
Check the downloaded PDF before sharing
- Open the saved copy in a second PDF reader, not only the editing tab.
- Check page count, rotation, annotation placement and signature size.
- Zoom into small text and print one important page when print output matters.
- Keep the untouched original under a different filename.
- For phone workflows, follow the Android and iPhone editing guide.
Edit PDF online free — know what changes are being made
LyfPDF adds text, marks, shapes, highlights and signatures on top of the PDF and exports a new copy. It is useful for filling forms, reviewing documents and signing files without an account. If you need to rewrite existing paragraph text as if it were a word-processing document, convert the PDF to an editable format first and verify the layout after conversion.
Convert PDF to Word when editable document text is the main goal, or use PDF to Text when you only need to extract selectable text.
