PDF Editor
Correct text on a PDF page in its own typeface, then merge, reorder, redact, watermark and number pages, before compressing or password-protecting on Save.
🔒 Everything happens in your browser — your PDF is never uploaded. Add text, signatures, images, shapes and highlights anywhere by dragging; cover anything you want gone; reorder, rotate, crop or split pages; then download.

Correct the text that is already there
Click anywhere in the text and the caret goes there — or, on a keyboard, Tab to the page, pick a line with the up and down arrows and press Enter. The arrows walk the page rather than one line, Shift selects across lines, and typing and deleting go in where the caret is. The words are replaced in the page's own instructions, in the typeface they were already in — nothing is laid on top, and the old wording is not left underneath for the person you send it to. The encoding is recovered from the document itself, so a corrected line matches the ones around it as long as the page has already printed every character you type; when it has not, a typeface that can draw it is added and the tool says so rather than quietly drawing the wrong shape. Find and replace changes a word on every page at once, one line at a time and each line in the typeface it was already set in; a phrase that runs across a line break is not found.
Everything else you need to edit a PDF, in one place
Drop in one or more PDFs — or pictures, each of which becomes a page the size of the page before it — and every page appears as a thumbnail. Reorder pages by dragging, rotate a page that scanned sideways, and delete the ones you don't need. Type on a page, drop in a signature or a picture, redact anything that must really go — the covered words are removed from the file, and the rest of the page keeps its selectable text — highlight, underline or strike through words, leave a comment note, add a link or change one already there, draw and crop. Form fields can be added too — text boxes, tick-boxes, either/or options, drop-down lists and a place to sign, left empty for whoever fills the form in; the boxes a form already has are filled in Form Filler. A page can be replaced with the pages of another file in one step. One button drops a text watermark across every page and another adds page numbers that count themselves — both land as ordinary items you can move, resize and restyle before you save. Unlike most online PDF tools your files are never uploaded — everything runs inside your browser.
One Save screen, instead of a separate tool for each job
Press Save… and a single screen offers everything you might want done to the file you are already saving: make it smaller (repacked with nothing re-drawn, or scanned pages squeezed hard), change it to greyscale or pure black and white, lay it out for printing (several pages to a sheet, folded into a booklet, or one page blown up across several sheets as a poster), lock it with a password, fix form entries in place so they can no longer be edited, and split it into separate files — every N pages, or just the pages you name. If the pages were measured as crooked there is also a straighten option, which turns each one back level; and if the document is a scan with no text of its own, a make the scanned words searchable option reads every page with OCR on your device and lays the words back as invisible text, leaving the scan itself untouched. It reads back a plain-language list of what saving will do before you press the button, including a warning when a choice would cost you selectable text.
It tells you what your file needs
Opening a document also points out what applies to it, rather than leaving you to search through a menu: pages that look blank — the kind a duplex scanner leaves behind — listed by number with one click to drop them; how far a crooked scan is tilted, with one click to straighten it; a scan carrying no text at all, with one click to read it and make it searchable; a form with boxes to fill in, with a link to the Form Filler that fills them; comments and highlights already in the file; and a file whose original blocked printing or copying, with a note that saving here makes a copy without those limits. A document that needs nothing says nothing.
Frequently asked questions
What can I do to a PDF here?
Merge multiple PDFs, add pictures as pages, and reorder, rotate, duplicate, delete or replace pages with those of another file; find and replace a word on every page; type text, place a signature or an image, highlight, underline or strike through text, leave comment notes, add or edit links, draw, cover something up or redact it for good, and crop. Then, on the Save screen: compress, convert to greyscale or black and white, lay pages out for printing several to a sheet or as a booklet or poster, set an open password, flatten form entries, and split into separate files, plus straighten the pages when the scan came out crooked and read a scan with OCR so it becomes searchable. A watermark and self-counting page numbers are one button each, and new empty form fields — text boxes, tick-boxes, either/or options, drop-down lists and a place to sign — can be drawn for someone else to fill in. All of it in one editor.
Are my PDFs uploaded?
No. Reading, editing, stamping and splitting all run locally in your browser; your files never leave your device.
How do I split a PDF?
Arrange your pages, then press Save… — splitting lives there, alongside the other things you might want done on the way out. Break the document every N pages, or type the pages you want to keep as "1-3, 5, 8"; multiple files download together as a zip.
Do I need a separate tool to compress the PDF or add a password?
No. Both are choices on the Save screen, along with greyscale or black and white, print layouts, flattening a form and splitting. They are applied in one pass over the file you are already saving, so a page is never re-drawn twice, and the screen lists what will happen before you commit.
When I merge PDFs, do the bookmarks in each file survive?
Yes, as long as "A bookmark for each file" is left on in the file view. The saved PDF gets one contents entry per document, and the bookmarks each document already had are kept underneath its entry, still pointing at the right pages. Switch it off and only the first document keeps its outline.
Can I split out a single page?
Yes — type its number under "Only some pages". For several separate pieces, write them as "1-3, 5, 8" and tick "Save each range as its own file". For every other page, "Odd and even pages" saves both halves at once.
Is rotating a page permanent?
Yes — it is written into the saved file, so it opens the right way round everywhere, unlike the temporary rotate button in a PDF reader.
When would I reverse a PDF’s page order?
Most often after a scan comes out back to front — for example when a stack of pages is fed the wrong way into a sheet-fed or duplex scanner, so the last page ends up first. Reversing the order puts everything back into reading order in one click.
How do I interleave the fronts and backs of a one-sided scan?
Open the editor’s interleave job — the old Interleave PDF Pages address opens it — and drop in the fronts, then the backs, or more files in the order they take their turns. Each file gets a row above the pages: tick “Read backwards” on one that came out last page first, as the backs often do when the stack is flipped; set how many pages it gives per turn (3 on the second file slots one page of the first between every three of it); or name the pages that take part, such as “1-3, 8”. Press Weave and the pages below are the woven document, which you can still reorder, rotate or delete before saving. “Pad the short files with blank pages” gives a file that has run out a blank sheet for each turn it misses, each the size of that file’s first page.
My scanner made one file with all the fronts and then all the backs. Can I fix that here?
Yes — open that one file on the interleave job and press Duplex sort. It is split down the middle and woven back into reading order: 1, n, 2, n-1 … A box says whether the backs were scanned in reverse, which is what happens when the stack is flipped; untick it if the backs were fed in the same order as the fronts, and the order becomes 1, h+1, 2, h+2 … You do not have to split the file first.
How does the remove-blank-pages job decide a page is blank?
Every page is drawn and measured: how much of it is darker than paper, and how many characters of text it carries. A page is marked when its marks cover less than the share you set — 0.08% to start with, the same rule the editor uses for its own note about blank pages — and it has fewer than three characters of text. Raise the setting to catch a scanned back with a stray speck or some bleed-through. A scan on cream or grey paper reads as one solid mark at the usual setting; lower “What counts as paper” and its blank pages show up. Both controls re-decide the marked pages at once, without reading the file again.
Will removing blank pages delete a page that has a few words on it?
Not unless you say so. A page with text on it is never marked however light it is, and the job tells you how many it kept back for that reason; tick “Pages with words on them can count as blank too” for a page that says only “This page intentionally left blank”. Each marked page shows in the page list how much of it is ink, any of them can be ticked to keep, nothing goes until you press Delete, and one Undo brings them all back. The pages that go can also be downloaded as a PDF of their own, to check before you throw the original away.
What size is a blank page I add?
The same size and orientation as the page it follows — the selected page, or the last page when none is selected — so it lines up cleanly with the pages around it. With "Add between", each blank matches the page before it. A picture added to the document becomes a page of that size too, with the picture fitted inside it. If you need a different size, run the saved file through Resize PDF Pages.
Can I watermark with my own logo instead of text?
Yes — use the Signature · Image button to place a picture, then set its transparency and switch on "all pages". It behaves exactly like the text watermark.
Do page numbers update if I add or delete pages?
Yes. They count themselves, so reordering, adding or deleting pages before you save renumbers everything automatically.
Does cropping delete the content outside the margins?
No. Cropping shrinks each page’s crop box, the visible and printable window, and its media box, the page itself, to the area you keep. The original content is still there, just hidden, so the crop is non-destructive. The trimmed area falls outside both rectangles, so it stays out of the way in every viewer and every printer.
Is a signature placed here legally binding?
It places a visible electronic signature — a picture of your signature stamped onto the page — which is what many forms, agreements, and contracts ask for. It is not a certificate-based cryptographic digital signature (PKI). If a document specifically requires a verifiable digital certificate, use a dedicated certificate-signing tool instead.
Is the redaction real, or just a black box on top?
Real redaction. The glyphs under each box are removed from the page content stream and the file is rebuilt without them. Unlike a black rectangle drawn over the page — which sits on top of text anyone can select, move, or copy from behind — the words are gone from the file, so there is nothing left underneath to recover.
