Edit a PDF in the browser, and 40 tools for the rest
Frisket is a PDF editor and 40 single-purpose tools. The editor changes the words that are already in a document; the tools each do one job to a file you hand them — join, cut, shrink, convert, stamp, lock — and tell you what they changed and what they could not.

The tools
Every tool has its own page: what it does, what it will not do, and the form to run it. The form is built from whatever the server is running at that moment, so a page can never offer you a setting the tool does not have.
Put documents together
Several files, or several passes of a scanner, that need to end up as one document.
- Merge PDFCombine several PDFs into one file, in the order you arrange them.
- Alternate & Mix PDFInterleave the pages of two or more PDFs — the fix for a document scanned in two passes, fronts in one file and backs in the other.
- Organize PDF pagesReorder, duplicate or drop pages by writing the order you want, for example 3,1,2 or 1-5,8.
Take documents apart
One long file that has to become several, or a few pages that have to come out of it.
- Split PDF by pagesSplit a document after chosen page numbers, or every N pages.
- Split PDF in halfCut a document into two halves.
- Split PDF by sizeSplit a document into parts no larger than a size you choose — for an email attachment limit or an upload cap.
- Split PDF by bookmarksSplit at the document’s own bookmarks, naming each part after its bookmark.
- Split PDF by textStart a new file at every page containing a phrase — “Invoice”, “Statement of account”, a customer number.
- Extract PDF pagesPull a page range out into a new document, leaving the original alone.
- Delete PDF pagesRemove a page range and keep the rest.
Make a file smaller or a scan straighter
The upload limit said 10 MB, or the scanner fed the pages in at an angle.
- Compress PDFMake a PDF smaller by re-encoding the images inside it, leaving text sharp.
- Deskew PDFStraighten pages that were scanned at an angle, by finding the tilt of the text lines and rotating the page back.
- OCR PDFReport which pages have a real text layer and which are images that would need OCR.
Get the contents out of a PDF
The words, the tables or the pictures, in a format something else can open.
- PDF to WordProduce a Word-openable document that keeps paragraphs and headings.
- PDF to ExcelDetect tables by the position of the text and export them as CSV, which every spreadsheet opens.
- PDF to textExtract the text layer as a plain text file, optionally keeping the page layout.
- PDF to JPGRender each page to a JPEG or PNG at the resolution you choose.
- PDF to PowerPointTurn each page into a slide-sized image with an index, for dropping into a deck.
- Extract images from PDFPull the images out of a PDF at their original resolution, skipping the tiny ones that are usually rules and bullets.
Make a PDF out of something else
Photos, a text file or a web page that has to arrive as a PDF.
Fix how the pages sit on the paper
Sideways, off-centre, the wrong size, or four pages that should print on one sheet.
- Rotate PDFTurn pages 90, 180 or 270 degrees, all of them or a range.
- Flip PDF pagesMirror pages horizontally or vertically — for a scan made through the back of a page, or artwork that needs reversing for print.
- Crop PDFTrim margins by setting how much to take off each side.
- Resize PDF pagesScale pages onto a standard paper size — A4, Letter, Legal — keeping the proportions and centring the content.
- N-up PDFPut several pages on one sheet — 2, 4, 6, 8, 9 or 16 — for handouts and proof prints.
- Greyscale PDFConvert pages to greyscale, for cheaper printing or a scan that came out with a colour cast.
Put something on every page
Numbering and marks that have to be identical on every page and never repeat.
- Add page numbers to PDFStamp page numbers where you want them, starting from any number, in the format you choose — 1, Page 1, or 1 of N.
- Add header and footer to PDFPut a line of text at the top or bottom of every page, with tokens for the page number, the total, the file name and today’s date.
- Bates numberingStamp sequential Bates numbers with a prefix, suffix and fixed width — the identifiers a court or a disclosure exercise expects, one per page, never repeated.
- Watermark PDFStamp text across the pages — DRAFT, CONFIDENTIAL, a name — at the size, colour, angle and opacity you choose.
Control what can be done with the file
A password to add or drop, or values that should be readable but no longer editable.
- Password protect PDFAdd a password and choose what may still be done with the file — printing, copying, changing.
- Unlock PDFRemove the password from a PDF you can already open, so you stop typing it.
- Flatten PDFTurn form fields — and optionally annotations — into ordinary page content, so the values can be read but no longer edited.
Tidy up the document itself
The properties, the outline, the leftover comments and the file that will not open.
- Edit PDF metadataChange the title, author, subject and keywords a PDF reports — the fields a document management system indexes and a reader shows in Properties.
- Create PDF bookmarksBuild an outline from the document’s headings, its pages, or text you match — so a long report gets a navigable table of contents.
- Remove annotations from PDFStrip comments, highlights, links or form fields.
- Repair PDFRebuild a damaged PDF page by page and report what could not be recovered.
- Rename PDFGive the file a new name and, if you like, set the document title to match — so it shows up correctly in a reader’s title bar and in search results.
Not sure what you are dealing with? The PDF inspector reports the page count and sizes, the PDF version, the metadata, whether the file is encrypted or tagged, and whether there is a real text layer or only a picture of one. It reads the file in your browser and uploads nothing.
The editor
Open a PDF and it appears as pages you can click into. Everything below happens on the page you are looking at, and “Apply changes” writes a new PDF you download.
- Change the text that is already in the document. The old glyphs are removed from the page rather than covered over, and the replacement is drawn with the document’s own font wherever that font can spell what you typed.
- Add text, images, links, shapes, highlights, stamps and whiteout, anywhere on any page.
- Fill in a form, or build the fields so somebody else can fill it in.
- Sign by drawing, typing or uploading a signature image.
- Rotate, reorder, insert, duplicate and delete pages from the sidebar.
One thing worth knowing before you rely on it: whiteout hides content, it does not remove it. The text under the white box is still in the file and can be pulled back out. That is how PDFs work rather than a shortcut we took, and the editor says so where you use it — if a name has to be gone for good, it needs redaction, not cover-up.
Guides
Answers to the questions people actually ask about PDFs — why the font changes when you edit one, why a scan will not compress, what a scanner’s black border really is. Each one is written to be useful whether or not you use anything here.
- Which merge keeps your PDF bookmarks?The outline is a tree of destinations pointing at page objects. Copying pages copies neither, so the navigation panel comes back empty on the far side.
- Split a PDF that is too big to even openThe usual advice is to compress it first, but nothing can compress a document it cannot render. Here is the order to use when nothing will load it at all.
- White bars round a PDF page on your slideA4 is 1:1.41 and a widescreen deck is 16:9, so the shapes cannot agree. Trimming the margins first closes the gap; rescaling afterwards does not.
- Is flattening the same as printing to PDF?One rewrites fields and annotations into page content; the other re-renders everything as a picture. What each one costs you: text, links, file size.
- Does renaming a PDF change what is inside?No — unless the tool also writes the new name into the document title. That one difference decides whether a signature still verifies afterwards.
- Put four photos on one PDF pageMost image converters give every picture a sheet of its own, which is the opposite of a contact sheet. Two steps get you a 2x2 grid instead.
Where your files go
The editor and the tools both run on our server, so the file leaves your computer: the editor uploads it as soon as you open it, because the server is what reads and rewrites the PDF, and a tool uploads it when you choose it. The inspector is the exception — it never sends anything anywhere.
What you upload is deleted after 2 hours, and the result you download after 24 hours, by a scheduled job rather than by somebody remembering. Nobody reads your documents and nothing about their contents is written to a log. The retention page lists the same numbers the code enforces and every company that can reach the storage; the privacy policy covers the rest.
