Ten tools

Pick the job. The file stays where it is.

How it works

The work stays in the tab.

Most online PDF tools are a website with a server behind it: you upload, it works, you download whatever it sends back. Folio is the tool itself, delivered to your browser and run there.

  1. You hand over the file

    Drop a PDF onto the page or pick one from your machine. The browser passes the bytes to the tab and no further — there is no upload step, and nothing waiting to receive one.

  2. Your machine does the work

    The editing, cutting, merging, compressing and encrypting all run as code inside the tab, against a copy held in memory. Your own processor is the one doing it, which is also why there is never a queue.

  3. You download the result

    The finished file is assembled in the tab and saved straight to your downloads. No watermark, no account, no emailed link. Close the tab and the document is gone with it.

Edit a PDF

Open a PDF and click any line of text to put a cursor in it, the way you would in a word processor. Folio matches the font, size and spacing already on the page, so a correction sits in the paragraph instead of on top of it. You can also drop in a new image, highlight or underline a passage, draw freehand, add a signature, and reflow the pages before you download.

  • Retype text in place, keeping the original font and spacing
  • Replace a logo or photograph without moving the frame
  • Highlight, underline, draw, sign and leave notes

Pages

Five ways to rearrange one file.

Merge, split, extract, delete, reorder. Each one is a whole tool of its own, each one works on pages you can see, and each one runs on the machine in front of you.

Runs in your browser

Merge PDF files

Add every file you want combined, drag them into the order you want, and download one PDF. Each file keeps its own page size and orientation, so a landscape scan dropped between two portrait reports stays landscape. If you only want part of a file, pick its pages before you merge rather than merging and then deleting.

  • Combine any number of PDFs into a single document
  • Drag the files into the order you want them read
  • Take only the pages you need from each file

Split a PDF

Choose where the cuts go and Folio hands back one file per part. Cut between two particular pages, cut every so many pages to break a long scan into even chunks, or type ranges to say exactly where each part starts and ends. The parts come down together as a zip when there is more than one.

  • Cut between chosen pages, or every so many pages
  • Type ranges to define where each part starts
  • Download the parts together as a zip

Extract PDF pages

Click the pages you want to keep, or type them as ranges, and download just those. The file you started with is left alone. Choose whether the pages come back as one document or as a separate file for each page, which is the quicker route when they are going to different people.

  • Pick pages by clicking them, or by typing ranges
  • Get them back as one PDF or one file per page
  • Leave the file you started with untouched

Delete PDF pages

Every page is shown as a thumbnail. Click the ones that should go, or type them as ranges when there are too many to click, and download the file without them. Nothing is removed until you download, so you can change your mind about a page right up to the last moment.

  • Click thumbnails to mark pages for removal
  • Type ranges instead, for longer documents
  • Change your mind before you download

Organize PDF pages

The whole document laid out as a grid you can rearrange by dragging. Turn a sideways scan the right way up, duplicate a page, delete one, or pull pages in from another file and drop them where you want them. This is the tool to reach for when the fix is not one operation but several.

  • Drag pages into a new order across the whole file
  • Rotate, duplicate or delete any page
  • Pull in pages from other files and place them

Finish

Before it goes out the door.

Make it small enough to send, lock it, take the lock back off, or convert it to DOCX.

Compress a PDF

Most of the weight in a large PDF is its images, so that is what Folio works on: pictures are resized and re-encoded until the file comes down, and the text stays sharp because text is not touched. You see the new size before you commit, and you can keep the original alongside the smaller copy.

  • Shrink the images while leaving text crisp
  • See the new size before you download
  • Keep the original copy if you want it

Password protect a PDF

Set a password that has to be typed before the document will open, and decide separately what someone may do once it is open — whether they can print it, copy text out of it, or change it. The file is encrypted on your own machine, so the password itself is never sent anywhere.

  • Require a password to open the document
  • Allow or block printing, copying and editing
  • Encrypt on your machine, not on a server

Unlock a PDF

For a file you can already open: give Folio the password once and get back a copy that does not ask for one, with the restrictions on printing and copying lifted too. This removes protection you are entitled to remove — it does not break into a document whose password you do not have.

  • Remove a password from a file you can open
  • Lift restrictions on printing and copying
  • Keep the locked original if you still need it

PDF to Word

Turns the PDF into a Word document you can open and edit in any word processor, keeping headings, paragraphs, lists and tables as real, editable formatting rather than pictures of them. This is the one tool that needs a server: the file is sent over an encrypted connection, converted, and the copy there is deleted as soon as the result is sent back, unless you are signed in and asked to keep it.

  • Convert to a .docx you can edit anywhere
  • Keep headings, lists and tables as real objects
  • Delete the server copy as soon as the result is sent back

What is different

Mostly, what isn’t here.

Folio’s advantages are absences, and absences do not show up in a feature list. So here they are, written down.

Questions

Everything people ask first.

Eleven answers, all on the page. Nothing to open.

Is Folio really free?
Yes. Every tool is free to use, with no watermark on anything you download and no sign-up required.
Are my files uploaded to a server?
Eight of the ten tools run entirely inside your browser tab, so the file never leaves your machine. Two send it over an encrypted connection: PDF to Word, because converting to .docx needs a server, and the editor when you download, so the PDF can be rebuilt with its own fonts. The copy there is deleted as soon as the result is sent back, unless you are signed in and asked to keep it.
Do I need an account?
No. You can open a PDF and download the result without signing up. An account only changes where a copy you keep is stored — in this browser, or in your account so it is there from another machine.
Can I edit the actual text in a PDF?
Yes. Click a line of text to put a cursor in it and type. Folio matches the font, size and spacing already on the page, so the correction sits inside the paragraph rather than on top of it.
What about scanned PDFs?
A scanned page has no text layer — it is a photograph of a page. Folio opens it as exactly that picture, so you can still mark it up, draw on it, sign it, and reorder or delete pages. What you cannot do is click a sentence and retype it, because there are no letters there to edit, only pixels.
Is there a file size limit?
The browser tools have no fixed cap: the limit is what your machine can comfortably hold in memory, so a very large scan is slower on a phone than on a laptop. PDF to Word runs on a server and does have caps — 50 MB and 50 pages.
What happens to my file when I close the tab?
It is gone. The document lives in the tab while you work on it, and nothing is written to disk unless you download it or tick “keep a copy” on the way out.
Does it work offline?
Not yet. The page itself has to arrive over the network, so you need a connection to open Folio. Once it has loaded, the work happens on your machine rather than over the wire.
Does it work on a phone or tablet?
Yes. Folio runs in any current browser on Windows, macOS, Linux, Android and iOS. The editor is most comfortable on a screen with room for the page and its panels side by side, but the page tools are happy on a phone.
Can it remove a password I have lost?
No. Unlock removes the password and the restrictions from a file you can already open — either because you know the password, or because only the advisory permission bits were set. It is not a way into a document you are locked out of.
Do I need to install anything?
No. Folio runs in the browser you already have open. There is no extension, no desktop app and no plugin.

Drop a PDF. Keep the tab.

No account, no install, no watermark. The tool is already here.
