The Best Free Tools for Bloggers in 2026
The Best Free Tools for Pinterest Bloggers in 2026
Most “best blogging tools” roundups are just affiliate link farms written by people who haven’t blogged a day in their life. You know the ones — 47 tools listed, zero context, and somehow every single one is “the best.”
This isn’t that.
This is the exact toolkit I use — and in many cases, the toolkit I built — for running a Pinterest-first blog. Every tool on this list is either completely free or has a generous free tier. And I’m going to be honest with you about what each one actually does, where it falls short, and when it’s worth upgrading.
The Pinterest angle matters. Pinterest is a search engine — not a social media platform. The tools that work for Instagram growth or Google SEO don’t always translate. You need tools built around keywords, image dimensions, and conversion tracking that matches how Pinterest actually works.
Here’s exactly what we’re covering:
Let’s get into it.
1. Pinterest Keyword Generator — Free
The single biggest mistake new Pinterest bloggers make is treating Pinterest like Instagram. They post pretty pictures, use generic captions, and wonder why nobody finds them.
Pinterest is a search engine. People type things like “boho living room ideas on a budget” or “how to make passive income blogging” into that search bar — and they expect relevant results. If your pins aren’t optimized for those searches, you’re invisible.
Keyword research for Pinterest is different from Google SEO. The intent is more visual, more aspirational, and the competition works differently. You need keywords that match what Pinterest users are actually searching — not just what Google users want.
The Pinterest Keyword Generator I built lets you enter your niche, topic, or blog post idea and get a list of Pinterest-optimised keywords instantly. Use them in:
- Pin titles and descriptions
- Board names and board descriptions
- Your Pinterest profile bio
- Blog post titles you’re writing content for
- Your content calendar planning
What it does: Generates Pinterest-optimised keyword lists based on your niche, topic, or blog post idea. Browser-based, no signup, instant results.
Best for: Writing pin descriptions, board titles, planning content around high-traffic, buyer-intent Pinterest search terms.
Limitations: Doesn’t show exact search volume data — for that you’d need a paid tool like Tailwind or KeySearch (covered below). But for most Pinterest bloggers starting out, this is more than enough.
2. Pin & Product Image Resizer — Free
A wrong-sized pin is a dead pin. Pinterest’s algorithm actively favors the 2:3 aspect ratio (1000×1500 pixels), and if your image is square, landscape, or cut off at a weird size, it gets buried in the feed before a human even sees it.
The problem is that most image resizing tools are either clunky desktop apps, subscription-based software, or web tools that upload your images to their servers (which is a privacy risk, especially if you’re working with client photos or proprietary product images).
The Image Resizer I built works entirely in your browser — your images are never uploaded anywhere. Drop in your files, pick a preset (Pinterest Pin, Amazon product image, Etsy listing, Instagram square, and more), and download perfectly sized images in seconds.
What it does: Instantly resizes images to exact platform specs with built-in presets for Pinterest (1000×1500), Amazon, Etsy, Shopify, Instagram, and more. Batch process multiple images at once.
Best for: Pinterest bloggers who create their own graphics, Etsy sellers, eCommerce bloggers, anyone tired of manually resizing images one by one in Canva.
Limitations: It resizes — it doesn’t design. For designing beautiful pin graphics, you’ll still want Canva* (free tier is generous). Use the Resizer after designing to make sure your dimensions are exactly right.
3. Blog Monetization Calculator — Free
Here’s a mistake I made early on: I spent $200 on Pinterest Promoted Pins without doing any math first. I didn’t calculate whether the expected traffic could realistically convert at a rate that would recoup that spend. It didn’t. I lost $200 I couldn’t afford to lose.
The Blog Monetization Calculator exists so you never make that mistake.
Before you spend money on any Pinterest-related investment — ads, a course, a scheduling tool subscription, a template pack — plug your numbers in first. Expected traffic, your product price, your realistic conversion rate. The calculator tells you whether the math works before you swipe your card.
I also use it the other direction: to figure out how much traffic I actually need from Pinterest to hit a monthly income goal. That number becomes my target. It makes the whole thing feel concrete instead of abstract.
What it does: Calculates expected ROI on any blogging investment — ads, courses, tools. Also works in reverse: plug in your income goal and get the traffic + conversion rate you need to hit it.
Best for: Bloggers planning their first product launch, running Pinterest ads, or deciding whether a paid tool subscription is worth it.
4. Email Marketing — MailerLite* (Free up to 1,000 subscribers)
Pinterest traffic is great. Email traffic is better. Here’s the difference: Pinterest sends you visitors. Your email list is an audience you own — no algorithm can take it away.
The goal of every Pinterest strategy should be: get the click → capture the email → own the relationship.
I’ve tested ConvertKit (now Kit), Mailchimp, and Beehiiv. For Pinterest bloggers who are just getting started, MailerLite is the one I recommend without hesitation. The free tier is genuinely generous (up to 1,000 subscribers, 12,000 emails/month), the automation builder is intuitive, and the landing page builder is good enough that you might not need a separate opt-in page tool at all.
What it does: Email marketing platform — opt-in forms, landing pages, automated sequences, broadcast newsletters, subscriber tagging.
Best for: Bloggers building their first email list, delivering lead magnet PDFs, and setting up a welcome sequence to nurture Pinterest traffic into buyers.
Free tier limits: 1,000 subscribers, 12,000 emails/month, some advanced features locked. Paid plans start at $9/month — still one of the cheapest in the market.

Quick Comparison: Email Marketing Free Tiers
| Tool | Free Subscribers | Automation | Landing Pages | Best For |
|---|---|---|---|---|
| MailerLite | 1,000 | ✓ Yes | ✓ Yes | Most bloggers starting out |
| Mailchimp | 500 | ✗ Limited | ✓ Yes | Basic newsletters only |
| Kit (ConvertKit) | 10,000 | ✓ Yes | ✓ Yes | Creators selling products |
| Beehiiv | 2,500 | ✗ Limited | ✗ No | Newsletter-first publishers |
5. Pinterest Scheduling — Tailwind* (Free trial)
Manual pinning every day is not a strategy — it’s a trap. You’ll burn out in three weeks, your consistency will collapse, and your Pinterest reach will drop because the algorithm rewards regular activity.
The answer is scheduling. And for Pinterest, Tailwind is the gold standard. It’s one of Pinterest’s official marketing partners, which means scheduled pins behave exactly like manually posted pins — no algorithmic penalty, no reduced reach.
The features that actually matter for Pinterest bloggers:
- SmartSchedule: Automatically posts at the times your audience is most active
- Board Lists: Pin to multiple relevant boards in one click
- Tailwind Communities: Share content with other bloggers in your niche for amplification
- Analytics: See which pins are actually driving clicks (not just saves)
What it does: Pinterest (and Instagram) scheduling, analytics, board list management, and content communities. Official Pinterest marketing partner.
Best for: Any Pinterest blogger publishing more than 5 pins a week who doesn’t want to be glued to their phone manually pinning every day.
Is it worth the cost? If Pinterest is your main traffic source and you’re publishing consistently, yes. The time it saves pays for itself. If you’re still figuring out your Pinterest strategy, start free and upgrade when you hit the manual-pinning wall.
6. SEO & Keyword Research — KeySearch* (From $17/month)
This is the one paid tool on this list I’d argue is worth it even when you’re starting out — if your blog relies on any Google traffic at all.
KeySearch is the budget-friendly alternative to Ahrefs and SEMrush. Those tools cost $99–$499/month. KeySearch is $17/month (or use the coupon code KSDISC for 20% off). For a blogger who needs keyword difficulty scores, competitor analysis, and backlink data — and doesn’t have a corporate budget — there’s nothing better at this price point.
For Pinterest-first bloggers, I use KeySearch primarily to research the blog post topics I’m creating content around — even if Pinterest is the traffic source, the posts need to have solid keyword foundations so they don’t live and die by Pinterest algorithm changes.
What it does: Keyword research, keyword difficulty scoring, competitor analysis, backlink checker, rank tracking, content assistant. Everything a blogger needs from an SEO tool.
Best for: Bloggers who want Google traffic in addition to Pinterest traffic, and need to know which keywords they can actually rank for vs. which ones are too competitive.
Use coupon code KSDISC for 20% off. * Affiliate link — I earn a small commission if you sign up.
Bonus: Free Pinterest Blog Monetization Roadmap PDF
All these tools are useless without a strategy tying them together. The Roadmap PDF is my attempt to give you that strategy in 10 pages — the exact 4-phase system I used to take Pinterest from zero to my blog’s #1 traffic source.
It covers the profile setup that gets you found in Pinterest search, the pin formula that actually gets clicks (not just saves), how to capture those visitors onto your email list, and what type of digital product sells best to Pinterest traffic.
It’s free. Delivered instantly when you sign up above.
