The everyday changes a document needs are small: a date to fill in, a figure to correct, a paragraph to strike out, a logo to drop on. None of them justify a subscription to a design suite, and none of them should mean uploading a contract to a stranger’s server. This opens the pages, lets you place things on them by clicking where they go, and writes the result out — with the original text, links and quality left exactly as they were underneath.
PDF is the universal document format: it locks layout, fonts and images so a file looks identical on every device and printer. Scans, invoices, forms, e-books and reports all travel as PDF. Because a PDF is a container rather than an image, turning its pages into JPG or PNG pictures — or bundling pictures into a PDF — are among the most common file tasks there are.
It is worth being straight about this, because it is the source of most of the disappointment people have with PDF editors. A PDF does not store paragraphs. It stores instructions to place particular glyphs at particular coordinates, in a particular font, and that is all. There is no sentence to put the cursor into and no paragraph that reflows when you add a word. Editors that promise otherwise are either reconstructing the text and re-laying it out — which moves everything and usually breaks the layout — or quietly doing what this does.
What this does is put things onto the page. Type a line where you click. Cover something up with an opaque patch and type the replacement over it. Highlight a passage. Draw a box around a clause. Drop in a logo or a scanned signature. That covers the changes documents actually need, and everything already on the page — text, links, fonts, quality — is left exactly as it was underneath.
Cover up, then type. It is what every PDF editor does for a correction, including the expensive ones, and it is worth knowing that this is what is happening: the old text is still in the file underneath the patch, so it can still be found by a search or recovered by someone determined. For a wrong phone number that is fine. For anything confidential it is not — use Redact PDF, which removes the content rather than covering it.
A translucent yellow block over text greys it out, which is not what a highlighter does. The highlight here is drawn in multiply mode, the same way ink on paper works: the yellow darkens the white of the page and leaves the black of the letters alone. The words stay as legible as they were, and they stay selectable — it is a mark on the page, not a picture of one.
Text you add is drawn with one of the fonts every PDF reader is guaranteed to have, which keeps it real, selectable, searchable text — and those fonts cover Western European characters only. A Turkish ı, a Greek word, Cyrillic or Chinese all fall outside that set. Rather than dropping the characters or swapping them for something that looks close, that line is drawn as a small, sharp image of itself instead, and the tool tells you it did. It looks right, which matters more than being selectable, and everything else on the page is unaffected.
The pages are rendered and the result is written in your browser. That matters here more than on most tools, because the documents people want to write on are contracts, offers, forms and invoices.
Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.
Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.
Not directly — a PDF stores text as positioned glyphs, not as editable paragraphs, which is why "editing" one is not like editing a document. What you can do is cover the old text with an opaque patch and type the replacement over it, which is how every PDF editor handles corrections and is exactly what the Cover up tool is for.
