Sign a quote, mark up a drawing, merge two files, put your own letterhead on top — all in a browser tab, with the file never leaving your computer. And a straight answer about the one thing no PDF editor can really do.
Every kitchen job produces paper that has to come back signed. A quote, a change order, a drawing with one dimension wrong on it, a delivery note. The document arrives as a PDF and the reply is expected as a PDF, and somewhere between those two things most people end up printing a page, signing it, photographing it at an angle and emailing the photo. There is a better way, it takes about a minute, and it does not involve uploading your prices and your address to a website you have never heard of.
A PDF is not a document in the way a word processor file is a document. It is closer to a description of a printed page: every letter is a glyph placed at fixed coordinates, in a font that is usually embedded, often subsetted down to just the characters used, and frequently renamed to something like ABCDEE+Arial. There is no paragraph, no line, no “the word after this one” — those are things a reader reconstructs by looking at positions.
That is why tools promising to “edit PDF text like Word” disappoint. To retype one line they have to guess which glyphs belong together, guess the font, re-flow whatever follows, and hope the substitute font has the same widths. Sometimes it works. Often the paragraph shifts, the alignment breaks, or the new text is visibly a different typeface from the line above it.
So it helps to split the word in two. Rewriting the text that is already there is the hard, unreliable half. Adding to the page — a signature, a note, a highlight, a box that covers something and new text on top of it, a whole extra page — is the easy, completely reliable half, and it is what nearly everyone actually needs. Everything below is the second kind.
Across every trade the list is remarkably short:
None of those require rewriting a single existing character. All five are one page away: flipkitchen.ca/pdf, free, no account, and the file is opened by code running in your own browser rather than on a server.
Signatures and initials are remembered on that device, so the next document is a single click. They are stored in your own browser’s local storage — not in an account, not on our servers — which also means clearing your browser data clears them.
One honest caveat worth knowing: this is a visible signature, a picture of your mark on the page, which is what an ordinary quote, change order or approval asks for. It is not a cryptographic digital signature with a certificate attached. If a lawyer, a bank or a government form specifically asks for a digital signature or an e-signature audit trail, that is a different thing and you will need a service built for it.
Marking up is where a kitchen project actually lives. The elevation shows a 36″ sink base where the plan says 33″. The quote lists two blind corners and the room only has one. You need to say so on the page, next to the thing, so nobody has to reconcile an email against a drawing.
Highlighter drags over a line and multiplies into the page, so the text underneath stays readable rather than being painted over. Sticky notes drop a yellow block wherever you click and print with the document — and they are also written into the file as real PDF comments, so they appear in the comments panel in Acrobat or macOS Preview as well. A note does not have to be a yellow block: the panel on the right tints it down so the page reads through it, or takes the background away entirely and leaves just the words. Strike-through and underline do what they say. For drawings there are a pen, straight lines, arrows, rectangles and ellipses, plus checkmarks and crosses for ticking off a list.
Everything you place stays editable: click it to select it, drag it, pull the handles to resize, use the panel on the right to change colour, thickness, opacity or angle, and press Delete to remove it. Nothing is committed until you download.
The strip on the left is the document’s page order, and it is fully editable.
1-3, 4, 5-8, or just the pages you ticked. More than one file arrives as a single .zip — which is how page 4 goes to the countertop shop without the prices going with it.A supplier’s quote that you are passing on to a customer looks better — and is less confusing — with your name on it. The letterhead panel takes a company name, a line underneath it, a contact line and a logo image, and lays them across the top of the first page or of every page, with a hairline rule under them.
What it produces is not a locked banner: it is an ordinary set of text and image marks, so you can nudge them, resize the logo, change the type size or delete one line afterwards. The details are stored in your own browser, so the next document you open is one click from being branded.
The same panel adds a footer, and the footer understands two tokens: {{n}} for the page number and {{total}} for the page count. “Northline Cabinet Co. · {{n}} / {{total}}” comes out as “Northline Cabinet Co. · 3 / 8” on the third page of eight, and keeps counting correctly if you add or delete pages afterwards.
A stamp is a bordered block of capitals with an optional date line under it — APPROVED, REVIEWED, DRAFT, FOR CONSTRUCTION, AS BUILT, RECEIVED, PAID, CONFIDENTIAL, VOID, COPY, or anything you type. Tick the option to put it on every page when you are stamping a whole set of drawings.
A watermark is the diagonal, pale, oversized version that runs across every page. Its most useful job is preventing an expensive mistake: a superseded drawing set that says DRAFT across it does not get cut, and a quote marked SAMPLE does not get paid.
This one matters, so it is worth being blunt about it. Dragging a white or black box over a price, a name or an address hides it visually. The text underneath is still in the file. Anyone can select it, copy it, or extract it with a script. Every year somebody publishes a “redacted” document that is redacted exactly this much, and every year somebody copies the text straight back out of it.
Covering is genuinely useful — for tidying a page, for hiding an old figure so you can type a new one over it, for anything where the point is presentation rather than secrecy. But if the point is that the information must be gone, tick flatten to images when you download. Every page is then re-rendered as a picture and packed back into a PDF: the text layer no longer exists, so there is nothing left under the box to copy. The trade is a larger file and text that can no longer be selected or searched — which, when you are redacting, is the entire point.
Flattening is also the reliable way to make sure a mark cannot be moved or deleted by whoever receives the file.
Marking things up by hand is fine for a page. It is hopeless for a twenty-page contract where a customer’s name, or a price you are not passing on, appears eleven times. So the editor reads the document’s text layer — the actual glyph positions, not a picture of them — and lets you search it.
Type a word into Find and every match lights up across all the pages, with arrows to step between them. Then one button acts on all of them at once: highlight them, strike them through, or black them out. The marks land on the words themselves, not near them, because they are placed from the same text positions the search found.
That last one is the reason this feature exists. Search, black out, then download with “flatten to images” ticked, and the word is gone from the file — not covered, gone. It is the difference between a redaction and a rectangle.
The same text layer makes the marker tools smarter everywhere else: drag the highlighter roughly across a line and it snaps to the line, at the line’s own height, instead of recording your wobble. Hold Alt while dragging if you actually wanted a plain box.
Under More are the jobs that come up once a month and are miserable without a tool:
Most free PDF tools on the web work by sending your file to a server, doing the work there and sending it back. That is a reasonable engineering choice and a bad fit for the documents this guide is about. A kitchen quote carries prices, a discount, a customer name and usually an installation address. A signed change order is a contract. Those are not things to hand to an unknown third party in exchange for deleting a page.
The editor here reads and writes the file entirely inside your browser tab. Nothing is transmitted, so there is nothing to store, leak or subpoena. The simplest way to convince yourself is to load the page, turn off your Wi-Fi, and then open a PDF, sign it and download it — it all still works, because there was never a server involved.
Being clear about the edges saves you the time of finding them:
Open flipkitchen.ca/pdf and drop the file on the page. It is opened, edited and saved by code running in your own browser, so the file is never transmitted anywhere. There is no account, no trial and no watermark on what you download.
Use the Sign button: draw your signature with a mouse, trackpad or finger, type it and choose a handwriting, or upload a photo of a signature you made on paper. Drag it onto the signature line, size it, and download. Your signature is remembered on that device for next time.
Not reliably, and no browser tool can. A PDF stores glyphs at fixed positions in fonts that are usually subsetted and renamed, so re-typing a line means guessing at the font and re-flowing everything after it. Cover the old text with a white box and type the new text on top — it prints identically and never breaks the rest of the page.
Open the first one, then drag the second onto the page area; its pages are appended to the end. Use the thumbnail strip on the left to drag them into the order you want, then download the combined file.
Every page appears as a thumbnail on the left with a small toolbar under it — the bin icon deletes that page. You can also tick several pages and delete them together. The last remaining page cannot be deleted.
Press Find, type the word, and every match lights up across the whole document. One button then blacks out all of them at once. Download with "flatten to images" ticked and the text under those boxes is genuinely removed rather than merely hidden.
Both are under More. Export images writes the pages out as JPG or PNG at screen, good or print resolution — one image, or a .zip of them all. Reduce size re-renders the pages at a lower resolution; it measures the result and shows you the before and after, because on a text-only document it makes the file bigger.
Yes, if the file really has form fields: More → Form lists them and you type into them, and the answers are locked in by default so they print and display everywhere. A file with no fields is not a problem either — use the Text tool and type on it.
Press Split. Every page as its own file, a cut in two after a page you choose, your own ranges such as 1-3, 4, 5-8, or only the pages ticked in the page strip. If it produces more than one file they arrive together as a single .zip, so nothing has to be downloaded one at a time.
In the page strip on the left, click the + that sits in the gap between any two thumbnails and choose a blank sheet, an image or another PDF — it goes in exactly there. The buttons at the top of the strip do the same thing after whichever page you are currently viewing, so a blank page can be sandwiched between two existing pages rather than only added at the end.
No. On its own it only hides the text visually — the words are still in the file and can be copied out. Tick "flatten to images" when you download and every page is re-rendered as a picture, which removes the text layer entirely and makes the redaction real.
Use the Letterhead panel: enter your company name, a line underneath, a contact line, and choose a logo image. It is laid across the top of the first page or every page and stays editable afterwards. The details are stored in your own browser so the next document takes one click.
Yes — the Stamp panel has APPROVED, REVIEWED, DRAFT, FOR CONSTRUCTION, AS BUILT, RECEIVED, PAID, CONFIDENTIAL, VOID and COPY, plus any text you type, with today’s date underneath if you want it. There is also a diagonal watermark that goes on every page at once.
It is a visible signature — a picture of your mark on the page — which is what an ordinary quote, approval or change order asks for. It is not a cryptographic digital signature with a certificate and an audit trail. If a bank, a lawyer or a government form specifically requires that, use a service built for it.
A quote signed, dated and returned in about a minute, without printing a page or handing your prices to a stranger.
