Overview

Free tools for authors that explain how they work

Authors meet a surprising number of small technical questions on the way to a published book. How many pages will 80,000 words make at this trim size? How wide is the spine? Is this ISBN valid? What does a 4.99 dollar ebook earn on each platform? Is the cover readable as a thumbnail? How many words a day will finish the draft by March? Each question has an answer that can be worked out in a minute with the right tool, and getting it wrong costs money or time. These tools exist to answer those questions quickly and honestly.

Every tool on this page runs in your browser. The text that you paste, the images that you check and the figures that you enter never leave your device, so the tools are safe for unpublished chapters, client work and private numbers. There is no account to create, no email to hand over and no limit on how often you use them. Each tool page also says how the result is calculated, which formulas it uses, which figures come from platform rules and where those rules can change, because a number is more useful when you know what it means.

The tools fall into six groups. The writing checks look at the text itself: length, readability, adverbs, filler words, dialogue and chapter balance. The formatting and print tools handle trim sizes, page counts, spines, colour, image resolution and fonts. The ISBN and code tools validate numbers and draw barcodes and QR codes. The money tools work out royalties, prices, costs and budgets. The generators suggest titles, names, descriptions and bios. The launch tools plan a timeline, build keywords and hashtags and collect your buy links. When a job is bigger than a tool, the services further down the page take over.

Authors looking for free writing tools for authors will find them here, from word counters to royalty calculators. People who search for the best free tools for authors usually want tools that are accurate, quick and free of sign-ups, and that is how these are built. They are free tools for self-published authors, free author tools online that run in your browser and a set of free book writing tools for the drafting stage. The free book formatting tools help you with trim sizes, spine width and page counts, and the free self publishing calculators cover royalties, print costs and budgets. These work as free KDP tools for authors and free tools for indie authors, with free author calculators for money questions and free book marketing tools such as hashtag and keyword generators. There are free book design tools such as the font pairing and thumbnail preview, free word count and readability tools for editing, and free ISBN and barcode tools for your cover. If you want the best free writing tools for authors, start with the word count tool and the readability checker.

How to choose

How to choose the right free tool

01

Start from the question

Ask what you need to know, such as how long, how wide, how much or how readable, and pick the tool that answers it. The group headings above follow those same questions, so you can scan them quickly.

02

Check the method on the tool page

Each page explains how the result is worked out, so you can judge whether the method fits your book and your platform before you rely on it for a decision that costs money.

03

Use two tools together

Many questions need a pair. The page count estimator and the spine width calculator answer one question between them, and a royalty calculator and a pricing calculator answer another, so try the neighbours of the tool you open first.

04

Confirm with the source

Printers and stores publish their own templates, calculators and rules, and those are the final authority. The tools get you close, help you plan and tell you which questions to ask the platform before you upload.

05

Save your figures as you go

Note the page count, trim size, price and royalty that each tool gives you in one place. These numbers feed into your cover brief, your listing and your budget, and keeping them together prevents mismatches later.

06

Come back after every change

Edits to the manuscript change the word count, the page count and therefore the spine and the print cost. Re-run the relevant tools after any major revision, so that your plan always reflects the current text.

Why use them

Why authors use free tools before they hire anyone

Private by design

Your text, your images and your figures stay on your device and are never uploaded to a server, so the tools are safe to use on unpublished manuscripts, draft covers and royalty figures that you want to keep to yourself.

Quick answers

Most tools give a result in seconds, so you can try several versions of a decision, such as another trim size, another price or a different page count, and compare the outcomes before you commit to any of them.

Honest about limits

Each tool page says what the tool cannot know and where platform rules can change, so you can judge how far to rely on the result and which figures to confirm with the printer or store yourself.

No sign-up and no limit

There is no account, no email address to give and no cap on use, so you can come back whenever a question arises in the middle of a project and get an answer without any barrier.

Built for self-publishing

The tools reflect the real choices that authors face with KDP, IngramSpark, ebook stores and audiobook platforms, using the terms and units that those services use, so the results translate directly into your uploads.

A route to help when you need it

When a job is bigger than a tool can handle, such as building a whole interior or repairing a rejected cover, a specialist can take it from there at a fixed price, using the figures that you have already worked out.

Work with a specialist

When a free tool is not enough

The tools answer questions, and a specialist finishes jobs. If you want finished files, a fixed price and a named person who owns the work, these are the services that follow from the tools.

Client reviews

What authors say about our author tool kit work

Verified reviews from authors who used our formatting service for a author tool kit after reading about it.

Historical fiction requires a formal, unhurried typography that feels appropriate to the period. The specialist understood this without me having to explain it at length. The result is elegant and exactly right.

Claire FontaineHistorical Fiction Author, BelgiumVerified client

My textbook had 200 footnotes, 45 tables, and a detailed index. Every element was formatted to academic publishing standards. My publisher accepted the files without requesting any corrections whatsoever.

Professor David ChenAcademic Textbook Author, SingaporeVerified client

Tight, clean, and exactly on brief. The chapter openers had the tension-driven feel the genre demands without being overdone. Upload to KDP was approved without a single correction requested.

James O'BrienThriller Author, IrelandVerified client

YA formatting needs to feel energetic but readable. Every chapter felt like an invitation to keep going. The page numbers, headers, and spacing all contributed to a fast, engaging reading experience.

Chioma ObiYoung Adult Romance Author, NigeriaVerified client

My memoir had photographs on almost every other page alongside the text. The image placement, captions, and page flow all look natural and professional. The print proof was exactly what I hoped for.

Conor GallagherSports Memoir Author, IrelandVerified client

Good work overall. The formatting was clean and the file passed KDP first time. I would have liked slightly more communication during the process but the end result was exactly what I needed.

Sakura TanakaUrban Fantasy Author, JapanVerified client

FAQ

Free Tools for Authors: questions answered

These are the questions authors ask most about free tools for authors, including the steps, the files and the cost. If your question about the author tool kit is missing, request a quote and a specialist will reply.

Are the free tools for authors really free?

Yes. Every tool is free to use, needs no account and has no usage limit, and nothing that you type is uploaded.

Do the tools upload my text or images?

No. Each tool runs in your browser, so your text, images and figures stay on your device.

Which free tool should I use first?

Start from the question that you need answered. The writing checks help with a draft, the print tools help before formatting, the code tools help before upload and the money tools help before you set a price.

How accurate are the royalty calculators?

They apply the published structure of each platform's royalties and let you edit costs and rates. Platform terms change, so check the current terms before you set a price.

Can I use the tools on a phone?

Yes. They work on phones, tablets and computers, and the layouts adapt to the screen.

Do I need to create an account?

No. There is no sign-up, and you can use any tool as often as you like.

Are the generators powered by artificial intelligence?

No. The generators fill fixed patterns with your own words in your browser and do not use a language model.

Can I download the results?

Many tools have copy buttons, and some provide a download, such as an SVG barcode, a QR code, a calendar file or a CSV list.

What if a tool gives a result that does not match my printer or store?

Trust the printer or store. The tools are planning aids, and each page tells you where to confirm the figures with the source.

Can I suggest a new tool?

Yes. Send a message through the quote form and tell us what you need, and we will consider it for the collection.

Do you offer paid services as well?

Yes. We format interiors and ebooks, design covers, fix files, publish books and build author websites, each at a fixed price.

Is it safe to use the tools with unpublished work?

Yes. Because the tools run in your browser and send nothing anywhere, they are safe for unpublished chapters and private figures.
