How can I compress image size under 100kb without losing quality

Best practical workflow

1. Resize first (most important)

Huge 2MB images are usually too large in dimensions, not just quality.

👉 Example:

If your site shows images at max 1200px width, don’t upload 4000px images.

✅ This alone often reduces size by 70–90%

2. Use modern formats (WebP or AVIF)

WebP → best compatibility (recommended)

AVIF → even smaller, but slightly less supported

💡 Compared to JPEG:

WebP = ~25–35% smaller at same quality

AVIF = ~40–50% smaller

👉 So your 2MB JPEG can already drop to ~300–500KB here.

And finally... Use CDN

Using a CDN (Content Delivery Network) is actually one of the best complementary solutions — but important:

👉 A CDN does NOT replace compression

👉 It enhances delivery speed + can automate optimization

✅ What a CDN helps with

1. Faster loading globally

A CDN stores copies of your images on servers worldwide.

So instead of:

User → your server (slow)

It becomes:

User → nearest CDN server (fast)

✅ Result: faster load times (especially important for images)

2. Automatic image optimization (big win ✅)

Modern CDNs can:

Convert images → WebP / AVIF automatically

Compress images dynamically

Resize based on device

👉 Meaning:

You can upload your original images, and CDN handles optimization.
