How to Fix Blurry Images or Screenshots on Blogger

If you have ever uploaded an image to your Blogger post and it came out looking blurry or pixelated, you are not alone. This is one of the most common frustrations among Blogger users, and the good news is that it is almost always fixable. I have been through this myself, and once I figured out what was causing it, the fix was surprisingly simple.

In this post, I am going to walk you through everything I know about why Blogger images go blurry and exactly how to fix it. No complicated code, no third-party tools needed for most cases. Just practical steps that actually work.

Why Are Your Blogger Images Blurry?

Before jumping into the fixes, it helps to understand what is actually happening. Blogger does a few things behind the scenes when you upload an image, and most of the blur problems come from one of these causes:

Blogger resizes your image to a preset display size when you choose options like Small, Medium, or Large during upload
The image URL contains a size parameter that limits how large the image renders
The original image was saved at a low resolution or high compression before uploading
The wrong file format was used for the type of image
CSS styling on your theme is stretching the image beyond its natural size

Each of these has a specific fix, and I will cover all of them below. But let me start with the one that made the biggest difference for me personally, because it is also the easiest to overlook.

The Fix That Worked for Me: Always Choose Original Size

When you upload an image in Blogger's post editor, a small menu appears that lets you choose how large the image should display. The options are usually Small, Medium, Large, X-Large, and Original Size.

For a long time, I was clicking Large or X-Large without thinking much about it. It seemed like the right choice since I wanted my images to look big on the page. But what I did not realize was that choosing any of those preset sizes was causing Blogger to scale my image up or down to fit that exact dimension, and that scaling process was what was making my images look blurry.

Screenshots were the worst. Every time I uploaded a screenshot to illustrate a tutorial step, it would come out soft and hard to read. The text in the screenshot especially looked smeared.

Then I tried selecting Original Size instead, and the difference was immediate. My screenshots were sharp, the text was clear, and everything looked exactly the way it did on my screen when I captured it.

The reason this works is simple. When you choose Original Size, Blogger displays the image at its actual pixel dimensions without any resizing. There is no upscaling or downscaling happening, so no quality is lost. The image renders exactly as it was uploaded.

If you have not tried this yet, go back to any blurry image in your post, click on it, and change the size to Original Size. In most cases, that will solve the problem immediately.

Fix the Image URL Directly in the HTML

Even if you choose Original Size during upload, Blogger sometimes adds a size token to the image URL in the background. This token looks something like /s400/ or /s800/ and it tells Blogger's image server to serve the image at that specific width in pixels.

If that number is smaller than the space your image is occupying on the page, the image gets stretched and looks blurry. This is especially common on wider blog layouts.

Here is how to fix it:

Open your Blogger post editor and switch to HTML view
Find the image URL in the code. It will be inside an img tag and will contain something like bp.blogspot.com
Look for a part of the URL that looks like /s400/ or /s800/ or any similar number
Change that to /s0/
Save the post and check how the image looks

The /s0/ parameter tells Blogger to serve the image at its original full resolution with no size restriction applied. This is the same as choosing Original Size from the editor, but done directly in the code. It gives you a bit more control, especially when editing older posts.

You can also use /s1600/ if you want to keep a size cap but still get much better quality than the default. For most blog content areas, 1600 pixels wide is more than enough and keeps file sizes reasonable.

Upload Images at the Right Resolution

One thing that surprises a lot of bloggers is that Blogger cannot make a low-resolution image look better. If you upload a small image and display it in a large space, it will be blurry regardless of any settings you change.

A good rule of thumb is to upload images that are at least as wide as your blog's content area. Most Blogger themes have a content column that is somewhere between 600 and 800 pixels wide. If your image is only 300 pixels wide and you display it at full column width, it will look blurry because it is being stretched to twice its original size.

For screenshots specifically, capture them at full screen or at the highest resolution your screen supports. If you are using a laptop or desktop, your screenshots are likely already high resolution. On a phone, make sure you are not using a compressed screenshot mode if your device offers one.

According to Google's web image guidance, serving images at their natural display size is one of the most effective ways to maintain visual clarity and improve page performance at the same time. Oversized images slow pages down, and undersized images look bad. The goal is to match the image resolution to its display size as closely as possible.

Use the Right File Format for Each Image Type

File format matters more than most people realize, and using the wrong one is a common cause of blurry or degraded images on Blogger.

Here is a simple guide:

Use PNG for Screenshots and Graphics

PNG is a lossless format, meaning it does not throw away any pixel data when it saves. This makes it ideal for screenshots, charts, infographics, text-heavy images, and anything with sharp edges or fine detail. If you save a screenshot as a JPEG and then upload it, you will notice a soft, slightly smeared look around text and edges. That is JPEG compression doing its job, and it is not what you want for screenshots.

Use JPEG for Photographs

JPEG handles photographic content well because the compression it uses tends to be less visible on images with lots of color variation and smooth gradients. For photos of people, places, products, or nature, JPEG at 80 to 90 percent quality gives you a good balance between file size and visual quality.

Consider WebP for Both

WebP is a modern image format developed by Google that delivers better compression than both JPEG and PNG while maintaining similar or better quality. According to Google, WebP images are typically 25 to 35 percent smaller than comparable JPEG files. Most modern browsers support WebP, and Blogger handles WebP uploads without any issues.

If your image editing tool supports exporting to WebP, it is worth switching to it for new uploads going forward.

Avoid Over-Compressing Images Before Upload

Sometimes the blur does not come from Blogger at all. It comes from how the image was saved before it was even uploaded.

Many image editors and even some online compression tools apply aggressive compression that visibly degrades image quality. If you run your image through a compressor and set the quality too low, no amount of Blogger settings will fix that blur because the pixel data is already gone.

When saving or exporting images for your blog, aim for:

JPEG quality: 80 to 90 percent
PNG: use lossless compression, not lossy
WebP: quality setting of 80 or above

Tools like Squoosh, which is a free browser-based image optimizer made by Google, let you preview the quality difference before saving. You can slide the quality setting and see exactly what the image will look like at that compression level before you download it. This is a great way to find the sweet spot between file size and visual quality.

Host Images Externally for Maximum Control

If you want complete control over how your images are stored and served, one option is to host them externally and embed them in your Blogger posts via direct URL rather than uploading through the Blogger editor.

When you upload an image directly to Blogger, it gets stored on Google's servers and the URL goes through Blogger's image serving system, which is where the size tokens like /s400/ come in. By hosting your image somewhere else and linking to it directly, you bypass that system entirely.

Popular options for external image hosting include:

Google Drive: Free, integrates well with Google products, but requires generating a direct link which can be slightly involved
Cloudinary: A dedicated image hosting and optimization service with a generous free tier and automatic format optimization
Imgur: Simple and free, though better suited for casual use than professional blogging

External hosting does add a step to your workflow, but it gives you more control and can also improve your blog's loading speed if the external host serves images through a content delivery network.

Check Your Theme's CSS for Image Stretching

In some cases, blurry images are caused not by the image itself but by CSS rules in your Blogger theme that are stretching images to fill their container.

A very common culprit is a rule like this:

img { width: 100%; }

This tells every image on your blog to stretch to 100 percent of its container's width. If your image is 600 pixels wide and your content column is 800 pixels wide, the image gets stretched by 33 percent and starts to look soft.

To check this, you can right-click on a blurry image in your browser and choose "Inspect" or "Inspect Element." Look at the computed styles for the image and compare the rendered dimensions to the natural dimensions. If the rendered width is significantly larger than the natural width, CSS stretching is likely the cause.

The fix is either to upload a larger source image or to adjust the CSS so it does not force images to stretch beyond their natural size. You can use max-width: 100% instead of width: 100%, which allows images to shrink on smaller screens without stretching on larger ones.

If you are not comfortable editing your theme's CSS directly, this is something worth being aware of when choosing a Blogger theme. A well-coded theme will handle image sizing responsively without causing quality loss.

Tips Specifically for Screenshot-Heavy Blogs

If your blog is tutorial-based or tech-focused, you probably use a lot of screenshots. Here are a few extra tips that make a noticeable difference:

Capture at Full Resolution

Always capture screenshots at full size without any zoom or scale reduction applied to your browser or screen. On Windows, you can use the Snipping Tool or Snip and Sketch. On Mac, Command + Shift + 4 gives you a precise region capture. Both produce high-resolution PNG files by default.

Do Not Resize Before Uploading

Resist the urge to resize your screenshot before uploading unless it is genuinely oversized (say, wider than 1600 pixels). Let Blogger handle the display size by choosing Original Size during upload. Resizing before upload and then letting Blogger resize again compounds the quality loss.

Annotate Before Compressing

If you add arrows, highlights, or text annotations to your screenshots, do that before any compression step. Annotation tools that work on the raw screenshot preserve quality better than annotating a pre-compressed image.

A Quick Checklist Before You Publish

Before hitting publish on any post with images, run through this quick checklist:

Did you select Original Size when inserting each image?
Is the source image at least as wide as your blog's content column?
Are screenshots saved as PNG, not JPEG?
Did you check the image URL for a small /s size token that needs to be changed to /s0/?
Does the image look sharp in the post preview before publishing?

Running through these five points takes less than a minute and will save you the frustration of publishing a post and later noticing blurry images that readers are struggling to make out.

Finally

Blurry images on Blogger are annoying, but they are almost always fixable once you know where to look. The biggest thing I want you to take away from this post is the Original Size tip during upload. That single change fixed the majority of my image quality problems, especially with screenshots, and it requires zero technical knowledge to apply.

After that, the URL fix using /s0/ is the next most powerful tool in your kit. And if you are building a tutorial-heavy blog where screenshots are a core part of your content, switching to PNG as your default format for those images will make a visible difference in how professional your posts look.

Good images make a blog feel trustworthy and polished. They show your readers that you care about the quality of what you are putting out, and that goes a long way toward keeping people on your page and coming back for more.
