Shortpixel Review: My Experience
If you’ve searched for a ShortPixel review before landing here, you’ve probably already seen a dozen posts telling you it’s “the best image optimization plugin for WordPress,” and honestly, I’m not going to argue with that. What I want to give you instead is something different: what ShortPixel actually looks like when you’re using it on the free plan, as a beginner blogger who hasn’t upgraded to paid yet, and isn’t in a hurry to.
I’m Prisca, and I run The Income Plug. This is Version 3 of my blogging journey. I’ve had two blogs before this one that didn’t survive, partly because I stacked too many paid tools too early and burned out trying to keep up with the monthly bills before I had any income coming in. So this time, I’m doing things differently. And ShortPixel is actually a good example of that new approach in action.
This review covers exactly what I’ve experienced on the free tier, nothing more, nothing fabricated about plans I haven’t used.
What ShortPixel Actually Is
ShortPixel is an image compression tool, available as a WordPress plugin or a standalone web/API service, that reduces the file size of your images without noticeably hurting their quality. Smaller image files mean your pages load faster, which matters for both user experience and SEO.
It supports JPEG, PNG, GIF, and PDF files, and it can convert images into next-gen formats like WebP and AVIF, which are lighter and load faster in modern browsers. You also get to choose among three compression levels: lossy, glossy, and lossless. Depending on how much quality you’re willing to trade for file size.
For a blog like mine, where every post has featured images and in-post screenshots, this matters a lot. Unoptimized images are one of the fastest ways to slow down a new WordPress site.
What's Included on the ShortPixel Free Plan
Here’s the part most reviews gloss over, because most reviewers are writing from the paid-plan experience. Since I’m on free, here’s exactly what that gets you:
- 100 free image optimization credits every month — but a credit isn’t spent per image, it’s spent per file. WordPress generates several thumbnail sizes for every image you upload, and ShortPixel optimizes (and charges a credit for) each one separately, not just the original.
- Access to lossy, glossy, and lossless compression settings.
- Automatic conversion to WebP and AVIF formats.
- Support for JPEG, PNG, GIF, and PDF files.
- No file size cap on the images you upload.
- Compatibility with major WordPress plugins like WooCommerce and NextGen.
- Automatic backup of your original, unoptimized images, so you can restore them if needed.
For a Month 8 beginner blog like mine, with a modest and still-growing image library, 100 credits a month covered me for a while, but once I understood that thumbnails count separately, it made a lot more sense why the number drops faster than it sounds like it should. It’s genuinely a usable free tier, not just a teaser designed to push you toward upgrading in week one.
What Happens When You Hit the Free Limit
Eventually, if you’re publishing consistently and using multiple images per post (which you should be), you’ll use up your 100 monthly credits. I did, around my sixth or seventh month of consistent posting.
When that happens, ShortPixel doesn’t delete anything or lock you out of your dashboard. It simply pauses image optimization until either your credits reset the following month, or you buy more, either a recurring Unlimited plan starting at $9.99/month, or a One-time credit package starting at $19.99 for 30,000 credits that never expires. (Pricing can shift, so I’d always confirm current numbers directly on ShortPixel’s site before deciding.)
That pause is the moment every free-plan user has to make a decision. And this is where my honest experience and the actual point of this post comes in.
Why I Haven't Upgraded (And Why That's Not a Complaint)
I want to be really clear about something: I am not writing this ShortPixel review to complain that the free plan “isn’t enough.” It’s doing exactly what a free tier is supposed to do. My decision not to upgrade yet has nothing to do with ShortPixel’s quality and everything to do with where my blog currently is.
Here’s my actual reasoning. I’m seven months into this blog, without meaningful traffic or income yet. Every tool I add that comes with a recurring monthly charge is a bet I’m making on a blog that hasn’t proven it can pay for itself.
I’ve watched this exact mistake sink my two previous blogging attempts. I stacked subscription after subscription in the excitement of starting, and a few months in, the monthly total became a source of stress instead of motivation. Eventually the guilt of “paying for tools I’m barely using” became one more reason to quit. It’s actually one of the specific mistakes I break down in Blogging Mistakes That Stop Beginners From Making Money, if you want to make sure you’re not repeating it.
This time, I’m being deliberate. Upgrading a paid tool should be a response to a real, current need, not something I do because a tool exists and looks useful. ShortPixel earning my money eventually is very likely. Right now, I have a free workaround that costs me a little time instead, and time is a resource I can currently afford more easily than a recurring subscription.
That’s the mindset shift I actually want beginner bloggers reading this to take away, more than anything about ShortPixel specifically.
My Manual Workaround (What I Do Instead of Upgrading)
Once I hit my monthly ShortPixel limit, here’s exactly what I do for the rest of that month:
- I compress images manually before uploading, using free external compression tools that don’t require an account or subscription.
- I aim to get every image under 100kb before it goes into a post. For most blog screenshots and featured images, this is realistic without a visible drop in quality.
- I resize images to the actual display width they’ll be shown at on my site, rather than uploading a full-resolution image and letting WordPress scale it down in the browser; resizing first cuts file size dramatically before compression even happens.
- I still run everything through ShortPixel again once my credits reset, so nothing permanently skips optimization; it just gets optimized a little later than usual.
Is this more manual than letting ShortPixel handle it automatically in the background? Yes. Is it currently worth the small amount of extra time to avoid an unnecessary recurring cost? For where my blog is right now, also yes. If you’re looking for more tools like this that don’t cost anything while you’re building your blog’s foundation, I put together a list in my post on Best Free Resources Every Beginner Blogger Needs.
Honest Pros and Cons of the ShortPixel Free Plan
Since this is a shortpixel review based purely on free-plan use, here’s my honest breakdown of that tier specifically, not the paid plans I haven’t touched.
Pros:
- 100 free credits a month is genuinely usable for a smaller, growing blog.
- Compression quality is strong; I haven’t noticed visible quality loss on lossy settings.
- Setup is simple, even if you’re not technical.
- Automatic backup of original images gives peace of mind.
- WebP/AVIF conversion happens automatically, which helps page speed without extra effort.
Cons:
- 100 credits disappear fast once you’re publishing regularly with multiple images per post.
- Once you hit the limit, optimization pauses completely until reset or upgrade; there’s no partial or reduced-speed option.
- The credit system takes a bit of getting used to if you’ve never used a tool like this before.
Nothing here is a dealbreaker. It’s simply the reality of a free tier, and knowing this upfront helps you plan around it instead of being caught off guard mid-month.
How to Know When It's Actually Time to Upgrade a Tool
This is the bigger lesson I want you to take from this shortpixel review, because it applies to basically every tool you’ll be tempted to pay for as a beginner blogger, not just this one.
There’s a real difference between two situations that feel similar but aren’t:
- “This tool isn’t good enough for what I need.”
- “I’m not ready to pay for this yet.”
The first is about the tool. The second is about your current stage. Confusing the two is how beginners end up either sticking with genuinely bad tools out of guilt or upgrading good tools before their blog can justify the cost.
A few questions I ask myself before upgrading anything, ShortPixel included:
- Is the free version actually blocking me from publishing, or just adding a small extra step?
- Does my blog currently have traffic or income that this upgrade would directly support or protect?
- Am I upgrading because I need to, or because I feel like a “real blogger” should have the paid version?
- Could I put this money toward something with a more direct impact on growth right now?
If a free workaround costs me a bit of time but no real money, and my blog isn’t yet generating income, the free workaround usually wins for now. That calculation will change as the blog grows, and when it does, I’ll upgrade without hesitation, because at that point the cost will be easy to justify against the value.
Staying consistent with smaller, deliberate decisions like this one is honestly a big part of why I’ve been able to keep showing up on this blog at all. I talk about that more in How to Stay Consistent With Blogging.

FAQ
Is ShortPixel’s free plan actually usable, or just a trial? It’s a genuine free-forever plan, not a time-limited trial. You get 100 image optimization credits every month, indefinitely, with no expiration on the plan itself.
Why did my credits run out after way fewer than 100 images? Because a credit isn’t spent per image; it’s spent per file. WordPress automatically generates multiple thumbnail sizes for every image you upload, and ShortPixel optimizes each one separately, so a single upload can use several credits at once. If you want more images to fit inside the free quota, go into ShortPixel’s settings and turn off optimization for thumbnail sizes you don’t actually need optimized.
What happens to my images once I run out of free credits? Nothing gets deleted or reverted. Optimization simply pauses for any new images until your credits reset the following month, or until you purchase more.
Do I lose my optimized images if I don’t upgrade? No. Any images you’ve already optimized stay optimized. The pause only affects new images uploaded after you’ve used your monthly credits.
Can I use ShortPixel without connecting it to WordPress? Yes. ShortPixel also works as a standalone web tool and offers an API, so you can compress images manually or integrate it into other platforms outside of WordPress.
Is manually compressing images before uploading a good long-term solution? It’s a reasonable short-term workaround while your blog is small and you’re managing costs carefully, but it does cost you time. As your image volume grows, an automated paid plan becomes more worth it.
Does ShortPixel reduce image quality noticeably? On the lossy setting, I haven’t noticed a visible drop in quality on my own images, though results can vary depending on the type and complexity of the image.
Conclusion
So that’s my honest ShortPixel review, based entirely on real, current, free-plan use, not a sponsored deep dive into features I’ve never touched. ShortPixel’s free tier gives you 100 solid image optimization credits a month, strong compression quality, and useful extras like WebP/AVIF conversion and automatic backups. When you hit that limit, nothing breaks; optimization just pauses until you reset or upgrade, and that’s exactly the point where I’ve chosen a manual workaround instead of a recurring subscription, for now.
That decision isn’t a knock on ShortPixel. It’s a reflection of where my blog currently is: seven months in, still building traffic and income, and being intentional about which costs I take on and when.
The real lesson here isn’t really about this one tool; it’s about learning to separate “this isn’t good enough” from “I’m not ready to pay for this yet,” because those two situations call for completely different responses. Stay on the free plan as long as it genuinely serves you, and upgrade when your blog’s growth actually asks for it. That’s the approach I’m using across every tool on this blog, not just this one, and it’s a big part of why this version of my blogging journey feels sustainable instead of stressful.
