What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 2 of the 28 other PDF editors we grade
Lumin is a cloud-based PDF editor that works with files in Google Drive and other storage. It covers text editing, page tools, redaction and e-signatures, and lets a team edit and comment on the same document. Plans are priced by team and by how many documents are completed each month.

No rating on record; a web app where you set up a workspace and connect Drive.

The report card
Best for sharing and signing PDFs in the browser
Lumin is a cloud PDF editor with sharing, e-signatures and a free plan, with plans from $9 a month. Every plan is capped by completed documents a month, and redaction and connectors sit on Business at $99 a month per team.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Starter is $9 a month and Pro $19 a month per team, so five people pay under $4 each on Pro; one person pays more than the $6.67 middle. Business is $99 per team. |
| Free plan and trial | C | Free plan with 3 completed documents a month, plus a 7-day trial of each paid plan. |
| Features | C | Editing, collaboration, e-signatures, Google Drive sync and AI tools. Redaction and domain control are Business only. |
| Ease of use | C | No rating on record; a web app where you set up a workspace and connect Drive. |
| Platforms and integrations | B | Web, iOS, Android and a browser extension, with eight integrations. No desktop program. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Lumin is for
- Fits if a small team edits and signs PDFs together in a browser
- Works for people who need a few signed documents a month at no cost
Who it is not for
- Tight if you handle many files, as Free allows 3 documents a month and Starter 10
- Watch out: a document counts as completed when you share, download, print or sync it
- Watch out: extra document blocks are added automatically unless an admin switches it off
- Pricey if you need redaction or Slack and Drive connectors, which need Business at $99 a month per team
- Not for you if you want a desktop program, as there is none
Good to know
Good for
- Teams that keep their documents in Google Drive
- Freelancers who need occasional edits and signatures
- Students who want a low-cost editor
Worth knowing
- Plans are capped by completed documents a month: 3 on Free, 10 on Starter and 200 on Pro and Business.
- A document counts as completed when you share, download, print or sync it, and extra blocks are added automatically unless an admin turns that off.
- Redaction, domain control and connectors such as Slack and Drive sit on Business, at $99 a month per team.
- The pricing page shows monthly figures only and does not say whether yearly billing is cheaper.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
The plain part of Lumin you could make: documents. What surrounds it you could not. The 5 things listed below take a company, not a weekend.
That makes this kind of software worth paying for, not this one in particular: 21 of the 28 other PDF editors grade higher. It costs $108 a year.
What you could make
- Documents: an app builder makes this well.
What you could not
- Editing the text inside a PDF without breaking its layout.
- A real app for iOS and Android. Something home-made would be a web page.
- Several people working in it at the same moment.
- It plugs into other products, Google Drive, Google Workspace and Slack among them.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Lumin’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
