Why images are slowing down your website
Images are usually the heaviest thing on a web page. Here is how much they actually cost you, why it affects your search ranking, and the fixes that matter most.
WebP vs AVIF vs JPEG
A practical comparison of the three formats that matter, with real file-size numbers, browser support as it stands today, and a clear recommendation for each situation.
How image compression actually works
Lossy versus lossless, what a quality slider really controls, why compressing twice damages an image, and what all of it means in practice.
Image formats explained
What each image format is genuinely good at, what it is bad at, and how to pick the right one without thinking about it twice.
Speed up WordPress by fixing its images
WordPress generates several copies of every image you upload. Here is how to stop that bloating your site, with and without a plugin.
What is EXIF data?
Your photos carry hidden metadata including GPS coordinates, camera serial numbers and timestamps. Here is what is in there and when it matters.
Social media image sizes
Correct dimensions for Instagram, LinkedIn, Facebook, X, Pinterest and YouTube, plus why uploading at the right size keeps your images sharp.
How to fix Largest Contentful Paint
LCP is the Core Web Vital most sites fail, and on most pages the culprit is a single image. Here is how to find it and fix it.
Client-side vs server-side compression
Where your images are processed changes what happens to them. A look at both architectures, what each is good for, and when the difference actually matters.
A batch image workflow that holds up
Practical process for handling large sets of images — naming, sizing, format choice and quality — aimed at photographers, agencies and anyone shipping a lot of assets.
Lazy loading images without breaking LCP
Browser-level lazy loading is one attribute and it works. It also quietly wrecks your Largest Contentful Paint if you apply it to the wrong image. Here is the line.
Stop images causing layout shift
Content that jumps while a page loads is nearly always an image with no reserved space. The fix is two attributes, and it has been the fix for years.
Responsive images: srcset and sizes
One image file cannot be right for both a phone and a 5K display. srcset lets the browser choose — but only if you tell it what it needs to know.
Image SEO: what actually matters
Most image SEO advice is folklore. Here is what Google actually documents, what alt text is really for, and the parts that genuinely move the needle.
SVG vs PNG vs JPG: when vector wins
Logos, icons and diagrams belong in SVG, and photographs never do. The dividing line is sharper than most format advice suggests.
Photo file size limits for visa and passport applications
Application portals reject photos for being too large — and, surprisingly often, for being too small. Here is why both limits exist, and how to hit an exact file size without wrecking the photo.
Lossy vs lossless compression
Lossless keeps every pixel and saves less. Lossy discards detail permanently and saves far more. Which one you want depends on what the image is — here is how to decide.
What JPEG quality setting should you use?
Quality 100 is nearly always a waste, and quality 60 is nearly always visible. Here is what the number really controls and where the useful range sits.
Why is my PNG file so large?
PNG files balloon for one of a few specific reasons — and the most common one is that the image should never have been a PNG at all.
How to remove metadata from photos before sharing
Photos carry GPS coordinates, timestamps, device serial numbers and more. Here is what is actually in there and how to strip it without damaging the image.
HEIC explained: why iPhone photos will not upload
Your phone saves photos in a format most of the web still cannot read. Here is what HEIC is, why Apple uses it, and how to get a file that works everywhere.
What image dimensions should you use?
Resizing saves more than compression does, and almost everyone skips it. Here is how to work out the pixel width an image actually needs.
How to compress an image to an exact file size
Upload limits are stated in kilobytes, not quality percentages. Here is how to hit a specific number without guessing your way there.
