I’ve been an indie author for six years and I’ve watched the cost of self-publishing creep up year after year. Canva went from free to $13/month for the features authors need. Adobe Acrobat Pro is $240/year. Vellum is $250 one-time but Mac-only. Atticus is $147. ProWritingAid is $99/year. PublisherRocket is $97 one-time. The tools alone can run $500+/year before you’ve sold a single book.
Here are seven free tools I actually use that cover the gaps. No subscriptions. No “free trial that auto-converts to $30/month.” Just things that work and cost zero.
1. BookReady PDF Compliance Scanner
What it does: drop your interior PDF, get an 18-point check against IngramSpark, KDP, B&N Press, and Draft2Digital specs in 30 seconds. Catches the things that actually trigger rejection emails: RGB color profiles, total ink coverage over 240%, unembedded fonts, image resolution under 300 DPI, odd page counts, missing bleed.
Why it’s on this list: the alternative is buying Acrobat Pro at $240/year just to verify your PDF is print-ready. The free scan handles the verification part. Even the $9-per-fix is cheaper than one month of Acrobat.
Link: bookready.net/app
Best for: anyone uploading to IngramSpark or KDP. Especially if you’ve been rejected before and don’t know why.
2. Reedsy Book Editor
What it does: browser-based manuscript writing and EPUB/PDF export. Better-looking PDFs than Word, no learning curve like Vellum or Atticus.
Why it’s on this list: the only fully free alternative to Vellum/Atticus that produces clean print PDFs. EPUB output is also professional-grade.
Link: reedsy.com/write-a-book
Best for: first-time authors who don’t want to learn Vellum’s interface and don’t have $250 to spend.
3. BookReady Cover Builder
What it does: drag-and-drop book cover designer with 43 genre-tuned templates (dark romance, romantasy, thriller, dark academia, etc), free Pexels stock photo search, full back+spine+front layout with auto spine width from your page count, ISBN barcode placeholder, 3D mockup preview, CMYK PDF/X-1a export.
Why it’s on this list: Canva Pro is $13/month and doesn’t natively export CMYK. CoverJig is $79/month for the plan that does CMYK. This is free to design, $9 once for the print-ready download or unlimited free with Pro.
Link: bookready.net/cover
Best for: anyone tired of paying Canva or struggling with PowerPoint cover hacks.
4. Hemingway Editor (free desktop version)
What it does: highlights long sentences, passive voice, weak verbs, and overuse of adverbs. The free desktop app does what the $19/year app does, with one less feature.
Why it’s on this list: ProWritingAid is $99/year and does more, but Hemingway is faster, simpler, and good enough for first-pass editing.
Link: hemingwayapp.com/desktop.html (the free desktop version, NOT the subscription web version)
Best for: anyone who can’t afford ProWritingAid or Grammarly Premium yet.
5. ISBN Barcode Generator
What it does: generates a print-ready EAN-13 barcode from your ISBN with the price extension built in. No watermark.
Why it’s on this list: every paid online generator wants either a credit card or a watermark. Most authors only need this once per book.
Link: bookready.net/tools (look for “ISBN Barcode Generator”)
Best for: anyone setting up a paperback who needs the barcode for the back cover.
6. KDP / IngramSpark Cost Calculator
What it does: estimates printing cost and royalty per copy for your specific trim size, page count, paper type, color/B&W, and list price. Tells you exactly what each platform will pay you.
Why it’s on this list: PublisherRocket charges $97 for tools that include this. The free version does just the print-cost piece, which is the part that matters.
Link: Both KDP and IngramSpark have built-in calculators (free, accurate). For trim/spine width: bookready.net/tools → Trim Size Calculator.
Best for: authors picking between platforms, or trying to set the right list price.
7. BookReady Author Landing Pages
What it does: drag-drop landing page builder with 14 genre templates, email signup form, custom subdomain, all hosted free.
Why it’s on this list: Carrd is $19/year for custom domains. Squarespace is $192/year. Wix Pro is $192/year. None of them have author-specific templates with cover-art slots, blurb sections, buy-link grids, and review carousels built in.
Link: bookready.net/page-builder
Best for: authors who need a single book’s landing page (not a full author site) and want it live in 20 minutes for free.
Honorable mentions (free things I recommend but didn’t make the seven)
- Amazon ACoS / KDP analytics: free in your KDP dashboard, surprisingly good
- Google Trends: free, useful for picking timely book topics
- Notion: free for individual use, great for tracking series notes / outlines
- Open Source Fonts: Google Fonts has 1,500+ commercial-use-free typefaces
- Affinity Publisher (one-time $70): not free but a one-time payment vs Adobe’s subscription. Industry-grade.
What’s missing from this list
- AI assistant: ChatGPT Free is good enough for blurb help and brainstorming. Claude Free has a smaller free tier but writes better fiction. Neither is “indie author specific” enough to make my main list.
- Beta reader management: a spreadsheet works as well as any paid tool here.
- ARC distribution to verified reviewers: this is the gap I’m trying to fill with BookReady’s ARC program — readers in your genre, FTC-compliant disclosure, $39 starter tier. Not free, but the only legitimate way to get ARCs into reviewer hands without buying fake reviews.
The honest take
Most “best free tools for authors” lists are SEO content written by people who’ve never published a book. The seven things on this list are tools I actually use every week. Your mileage varies based on genre and process, but if you’re staring at a Canva subscription you can’t afford or a Vellum license you keep meaning to buy, this is your zero-budget alternative stack.
The big-picture math: with these seven free tools, the only paid thing you genuinely need to publish is your ISBN ($125 from Bowker for one, or $295 for ten — but Amazon’s free ISBN works for KDP-only authors).
If something here saved you money, send me a thank-you email and tell me what tool you wish I’d build next. I read every reply.
