Optimise WordPress Images
Shrink your WordPress image file sizes without a visible drop in quality.
The Problem
Your site is slow mainly because of large, unoptimised images — full-resolution photos straight from a camera or phone, uploaded without any compression, adding seconds to every page's load time.
About this problem
Images are consistently the single biggest contributor to slow page loads on content-heavy WordPress sites, often outweighing every other optimisation combined. Compression can shrink most photos by 50-80% in file size with no visible quality loss to the average visitor, but doing this safely across an entire existing media library — not just new uploads — takes the right tooling and settings for your specific content.
This is especially impactful on sites with lots of product photos, blog header images, or portfolio galleries that were never compressed on the way in.
What's Included
- Compressing your existing media library images without a visible quality drop
- Setting up automatic compression for future uploads going forward
- Resizing any images that are serving at a far larger resolution than they're displayed at
- Before/after comparison of total media library size and page load impact
What's NOT Included
- Converting images to next-gen formats like WebP (see the dedicated WebP conversion service)
- Redesigning how images are used/laid out on the site
- Re-compressing images you specifically want to keep at full, uncompressed quality (just tell me which ones)
How It Works
- Audit the current media library for the largest, least-optimised images and estimate total potential savings.
- Apply lossless or visually-lossless compression across existing images at scale.
- Resize any images that are uploaded far larger than their actual display dimensions on the site.
- Configure automatic compression for future uploads so the problem doesn't creep back.
- Measure total media library size and page load time before and after to confirm the real-world improvement.
In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.
Frequently Asked Questions
- Will compressing my WordPress images make them look worse?
- Done properly, no — the goal is visually-lossless or near-lossless compression, where the file size drops significantly but the quality difference isn't noticeable to visitors.
- How much can image optimisation actually speed up my site?
- It varies by site, but since images are typically the largest part of total page weight, a 50-80% reduction in image file size often translates directly into a meaningfully faster page load.
- Does this fix both existing images and future uploads?
- Yes — existing images in your media library get compressed as part of this, and automatic compression is set up so new uploads are optimised going forward too.
- Is image optimisation the same as converting to WebP?
- No — compression reduces file size within the same format (JPG/PNG), while WebP conversion changes the format entirely for further savings; they're complementary and can be done together.
- Will my original, uncompressed images be lost?
- Not unless you want them to be — a backup of the originals can be kept if you'd prefer that extra safety margin, just let me know upfront.
