Make a PDF small enough to email
It's almost always the photos. A phone photo or a full-resolution scan can be ten times bigger than it needs to be on a page. Redraw them at a sensible size and the file shrinks without touching the text.

How it works
Make a PDF small enough to email, step by step
Optimise PDF is on whenever you download. Big photos are redrawn at print quality (about 150 dots per inch at the size they're shown) and unused parts are dropped. Words and drawings are never changed. If the file wouldn't get any smaller, you get the original.
- Open the PDF. In your browser.
- Leave Optimise PDF ticked. It's on by default.
- Download. The smaller file, after a free sign-in.
Then keep going. Still too big? Split it into parts. Need it locked? Add a password. Same window.
Check it worked
Compare the two files' sizes in your downloads folder. A PDF full of photos or scans usually shrinks a lot; a text-only one hardly changes.
Where offices use it
- A scanned contract that bounces off the client's inbox
- A photo report for a supplier portal with a size limit
- A document for an ATO or government upload

Tools
From a messy scan to a PDF you can send
Merge PDFs
Add other PDFs to the end of this one.
Split PDF
Download a page range, like 1-3, 7, as its own PDF, or split the file into one PDF per range.
Add pages
Add a blank page, pages from another PDF, or an image as a page, wherever you like.
Delete pages
Delete the pages you choose.
Rotate pages
Rotate pages left or right.
Reorder pages
Move a page to a new position, or drag the thumbnails.
Edit text
Click a line of the PDF's own words to change it. The old words are removed from the file.
Add text
Put your own words anywhere on a page, as real text: tap where they go, type, then move them, and choose the font, size, colour and bold.
Fill and sign
Fill in a form, sign, add text, draw, highlight, or stamp APPROVED, PAID, RECEIVED, a date or your own words.
Redact
Black out parts of a page permanently. The page becomes a picture, so the covered words can't be copied or found.
Cover with white
Cover part of a page with white. This only hides it, and the words underneath can still be copied.
Flatten form
Make filled-in form fields and notes part of the page, so they can't be changed.
Make text searchable (OCR)
Read the words in a scan on this device and add them as hidden text, so the PDF can be searched and copied.
Export to Word or Excel
Turn tables into .xlsx or .csv and text into .docx, with a preview first. Best for typed PDFs.
Images to PDF
Make a PDF from JPG or PNG images, one image a page.
Add a password
Encrypt the PDF (AES-256) so it opens only with a password, with limits on printing, copying and changes.
Add fields
Put Signature, Initials, Date, Text and Checkbox fields on the page, so anyone can fill it in and sign it, here or in any PDF reader.
Request signatures
Send this PDF to up to 20 people to sign. They don't need an account, and everyone gets the signed copy with a Certificate of Completion.
There's also thumbnails and outline, search, zoom, print, download, fill in forms, add text, draw, highlight, add an image and sign. One honest limit: Edit text, Make text searchable (OCR) and Export to Word or Excel work best on typed PDFs and clear scans. A crooked phone photo of a docket will still read, just not perfectly, and we'd rather you heard that from us first.
Signatures
Sign it and send it back
Most of what gets signed in a small business is a quote, a variation or a timesheet, and printing one out just to sign it and scan it back wastes a morning. Open Fill and sign, draw or type your signature or use a photo of it, put it where it goes and download. Form fields fill in the same way. On the Team plan we keep your saved signatures so they follow you to any device you sign in on, and only you can use them.
Most Australian business documents can be signed electronically under the Electronic Transactions Act. Wills and some deeds are exceptions, so check with your adviser if you're not sure.
- Draw, type or upload a signature
- Stamp it Approved or Paid, or with today's date
- Flatten form, so filled-in fields stay put
- Keep up to five signatures on the Team plan
Privacy
Your PDFs stay with you
Nothing is uploaded
We built it on PDF.js and pdf-lib so the work happens inside your browser. The file you open never reaches us, so there's nothing for us to keep, lose or look at.
Works offline
Install it as an app and it opens without a connection, which helps on site where the signal drops out. You can open PDFs with it from "Open with" on your computer, too.
Redaction that removes the words for real
A black box drawn over the words leaves them sitting underneath, ready to copy. We rebuild each redacted page as a picture and remove bookmarks, the title, metadata or attachments that mention the covered words. The trade-off is that the rest of that page's words can't be selected afterwards.

Questions
Good to know
Will the text look worse?
No. Optimise PDF never touches text or drawings. Only large photos are redrawn.
How much smaller will it get?
It depends on the file. One full of photos or scans shrinks a lot. A text-only PDF hardly changes, because there's little to remove.
Is my file uploaded?
No. The work happens in your browser, so the file stays on your computer. A file only leaves it if you choose Save to Team, a share link or Request signatures on the Team plan.
Do I need an account?
Not to open or edit. You sign in when you download (free, no card), and that gives you 5 downloads a week.

PDFs are one job. What about the rest of the paperwork?
Autonome's Gadgets do the weekly admin, from supplier bills to timesheets and quotes, and wait for you to approve anything that matters. They work with Xero, MYOB and the apps you already use.
