How to Batch-Prepare Images for Your Website
A web-ready image is really four jobs in a trench coat: resize, compress, convert to WebP, and rename. This guide explains each one, the order that gets the best result, and how to run all four on a whole folder in a single pass instead of juggling four separate tools.

The four jobs of a web-ready image
A camera original is not a web image. Turning one into the other is really four separate jobs, and skipping any of them leaves performance on the table:
- Resize the dimensions down to what the page actually displays.
- Compress to cut the file size without visible quality loss.
- Convert to WebP for a smaller file at the same quality.
- Rename to a descriptive, SEO-friendly filename.
Each one has its own deep dive, from compressing without losing quality to picking the best format for the web. This guide is about doing them together, efficiently, on more than one image at a time.
The order that matters
Order changes the result. Resize first. Most of an image's weight comes from its pixel dimensions, so shrinking a 4000-pixel photo to 1600 removes the bulk before anything else runs. Compress second, on the already-smaller image. Convert to WebP third, so the format saving stacks on top of the compression. Rename last, once the file is final. Get the order wrong by hand and you do redundant work; a pipeline that bakes in the order removes the question entirely.
Running all four in one pass
Doing this manually means four tools and four exports per image, which is fine for one photo and miserable for fifty. The SammaPix WebLift tool runs the whole pipeline at once: drop in a batch, and every image comes out resized, compressed, converted to WebP, and renamed, in a single download. A folder of fifty images becomes one job instead of two hundred steps.

Renaming is the step people drop, because it feels separate from performance. It is not. Search engines read filenames, so red-leather-armchair.webp tells Google something that IMG_4821.webp never will, and that feeds image search and on-page context. The trouble is that renaming files one by one is the most tedious job of the four, which is exactly why it gets skipped. Folding it into the same pass, ideally with AI-generated descriptive names, is the only way it reliably happens. For the SEO detail, see our guide on AI image renaming for SEO.
When a pipeline beats single tools
A pipeline is for bulk preparation: a batch of product shots before a store upload, a folder of photos before a site migration, every image for a new page at once. When you only need one job on one image, a focused tool is quicker, so reach for the standalone compressor or WebP converter instead. For a single blog image specifically, see what size blog images should be. The pipeline earns its place the moment you are doing all four jobs on more than a handful of files.
FAQ
What does it mean to prepare an image for the web?
It means four jobs: resizing it to a sensible width, compressing it to a small file size, converting it to a modern format like WebP, and giving it a descriptive filename for SEO. Done together, these turn a heavy camera original into a fast, search-friendly web image.
What order should I do these steps in?
Resize first, because shrinking the dimensions removes most of the weight. Then compress, then convert to WebP, then rename. A tool that does all four in one pass handles the order for you, which is why a single pipeline beats four separate tools.
Can I do a whole folder at once?
Yes, and you should. The SammaPix WebLift tool takes a batch of images and resizes, compresses, converts to WebP, and renames them in one pass, so a folder of fifty images is one job rather than two hundred manual steps.
Why rename images for the web?
Search engines read filenames. A file called red-leather-armchair.webp tells Google more than IMG_4821.webp, which helps the image rank in image search and adds context to the page. Renaming as part of the same pass means it never gets skipped.
Does this help page speed and SEO?
Directly. Images are usually the heaviest part of a page, so resizing and compressing them improves Core Web Vitals, which Google uses for ranking. WebP cuts the weight further, and descriptive filenames add image-search visibility. Together they make pages faster and more findable.
