PDF Editor
A real PDF editor that runs entirely in your browser. Rewrite existing text, delete images from the file, fill in form fields, sign, highlight, add pages or images, rotate and reorder — then download. No upload, no account, no watermark: your document never leaves your device.
How to use the PDF Editor
- 1Click Open PDF, or drag a file straight onto the page area — the document is read into your browser's memory and rendered page by page, with thumbnails down the left side.
- 2To change wording that is already in the document, choose Edit text and click the word or line you want to change, then type over the editable copy that appears; press Escape or click elsewhere to commit it.
- 3To add your own content, pick Add text, Highlight, Cover, Draw / sign or Image, then click or drag on the page. Use the colour and size controls to style what you create, or to restyle whatever you have selected.
- 4To remove a picture from the file, choose Delete image — every image on the page is outlined — then click the one you want gone.
- 5Set colour and size before you draw, or select an object and change them — the colour panel has swatches, a HEX box, R/G/B fields, and an eyedropper that samples any colour already on the page.
- 6If the PDF is a form, fill the fields directly on the page; tick lock before downloading if you want the values flattened into permanent page content instead of remaining editable.
- 7For a scanned document, press OCR page to add an invisible searchable text layer, then click Download to save the finished PDF to your device.
About the PDF Editor
PDF Editor is a full editing surface for PDF files that runs entirely inside your browser tab. It renders each page with pdf.js, lets you work directly on top of that rendering, and writes your changes back into the file with pdf-lib when you download. Because every step happens locally, the document you open is never uploaded, queued on a server, or retained anywhere after you close the tab — which is what makes it usable for signed contracts, invoices, medical forms, and anything else you cannot hand to a third-party service.
The editing model covers the four things people actually need. You can rewrite text that is already in the document: click a word with Edit text and the editor samples the page background, covers the original with a matching patch, and drops an editable copy on top at the same size and colour so you can retype it. You can delete images that are already in the file — not paint over them, but remove the drawing instruction from the page content stream so the image genuinely leaves the document. You can fill in existing form fields, which appear as real text boxes, dropdowns and checkboxes positioned exactly over the PDF's own widgets. And you can add your own layer: text, highlights, white-out patches, freehand drawing for a signature, and PNG or JPEG images.
Page-level work is here too: rotate a page in either direction, delete a page, extract a single page into its own file, or merge several PDFs into the one you are editing. Annotations follow the page when you rotate it, so nothing drifts off the content. Scanned documents can be run through OCR, which writes the recognised words back as an invisible text layer — the scan looks identical but becomes searchable and selectable, and the plain text is copied to your clipboard. Undo covers every edit, and the toolbar colour and size controls apply both to the next object you create and to whatever is currently selected.
One limitation deserves to be stated plainly rather than buried: covering text is not redaction. The original characters remain inside the file underneath the patch and can be pulled back out with any text-extraction tool. That is a property of how PDFs store content, not a shortcut taken here, and it is true of most in-browser editors. Use the cover tool to correct a typo, update a date, or tidy a layout — never to hide a personal identification number, a bank account, or anything you would be harmed by disclosing. For those, use a tool built specifically for redaction, and verify the result by extracting the text afterwards.
Frequently asked questions
How do I change the colour of text, highlights or drawings?
Click the colour button in the toolbar to open the colour panel. It offers ten common swatches, a HEX field, separate R, G and B boxes (0-255), and the system colour picker. Whatever you choose applies to the next object you create and to the object currently selected, so you can restyle something after the fact. In Chrome and Edge the panel also has an eyedropper: click 'Pick colour from the page' and click any pixel of the document to copy that exact colour — the quickest way to match text you are rewriting.
Is my PDF uploaded anywhere?
No. Rendering, editing, OCR and saving all run as JavaScript inside your browser using pdf.js and pdf-lib. The file is read into memory on your own machine and the edited copy is handed back to you as a download. Nothing is transmitted to a server, nothing is logged, and nothing survives closing the tab — which is why the editor keeps working even if you go offline after the page has loaded.
Can I really edit the text that is already inside the PDF?
Yes, within the limits of the format. PDFs do not store editable paragraphs — they store positioned glyphs — so the editor covers the run of text you clicked with a patch matched to the page background and places an editable copy on top at the same position, size and colour. You retype it and the result looks like a direct edit. Text does not reflow automatically, so if your replacement is much longer than the original you may need to move it or reduce the size.
Is covering text the same as redacting it?
No, and this is the most important thing to understand about any in-browser PDF editor. The original text stays in the file underneath the patch and can be recovered with a text-extraction tool, even though it is invisible on screen and in print. Use covering for corrections and layout fixes. For personal identification numbers, bank details, medical information or anything legally sensitive, use a dedicated redaction tool that removes the content from the page stream, and verify by extracting the text from the saved file.
How is deleting an image different from covering it?
Deleting an image is a genuine removal. The editor scans the page content stream, finds the instruction that draws that specific image, and removes it, so the picture is no longer part of the document at all. Covering only paints a rectangle on top. If the same image is placed more than once on a page, each placement is outlined and removed separately.
What does OCR do to my scanned PDF?
It recognises the words in the page image and writes them back as an invisible text layer positioned over the matching words. The page looks exactly as before, but the document becomes searchable, the text becomes selectable and copyable, and the recognised text is also placed on your clipboard. The recognition data is downloaded once on first use and cached by your browser afterwards.
Will my accented characters survive editing?
Yes. The editor embeds a Unicode font (Noto Sans) for everything it writes, so accented and non-English Latin characters such as č, ć, š, ž, đ, ü, é and ñ appear correctly in both added text and filled form fields. The 14 built-in PDF fonts cannot represent those characters, which is why many simpler tools drop or mangle them.

Frequently asked questions
Are my PDFs uploaded to a server?+
No. Every operation — rendering, editing, OCR and saving — runs inside your browser using JavaScript. The file never leaves your device, which is why the editor also works offline once the page has loaded.
Can I edit the text that is already in the PDF?+
Yes. Pick “Edit text” and click a word: the editor covers the original with a patch matched to the page background and drops an editable copy on top, matching the size and colour, so you can retype it.
Is covering text the same as redaction?+
No, and this matters. The original text remains inside the file underneath the patch and can be recovered with text-extraction tools. Never use it to hide personal, financial or confidential data — use a dedicated redaction tool for that.
Can I remove an image from a PDF?+
Yes. “Delete image” outlines every image on the page, and clicking one removes its draw instruction from the page content — the image genuinely disappears from the file rather than being painted over.
Does it work on scanned PDFs?+
Run OCR on the page. The recognised words are written back as an invisible text layer, so the scan looks identical but becomes searchable and selectable. The OCR language data is downloaded once on first use.
Can I fill in a PDF form?+
Yes. Existing AcroForm fields appear as real inputs on top of the page — text boxes, dropdowns and checkboxes. Tick “lock” before downloading to flatten the values into permanent page content.
