How to compress images without obvious quality loss

Practical steps to compress images (JPG, PNG, WebP, AVIF) while keeping them sharp. Learn when to resize and which format to convert to.

If you want to compress an image without obvious quality loss, start with the easiest win: resize to the actual display size. Many images are uploaded at 2–5× larger than needed.

For photos, compress using JPG/JPEG quality around 80–90, or convert JPG to WebP/AVIF for smaller files at similar quality.

For screenshots, logos, and UI, keep PNG when you need perfect edges and transparency. If the PNG is too large, try palette PNG or convert PNG to WebP (lossless or high-quality lossy).

Always compare results at 100% zoom for text and edges. The goal is to reduce file size while keeping the image looking natural.

FAQ

What’s the best quality setting for JPG compression?

A common sweet spot is 80–90 for photos. If you see artifacts, increase quality; if file size is still large, convert to WebP or AVIF.

Should I compress PNG or convert PNG to WebP?

If you need PNG features (lossless pixels, transparency), compress with PNG presets. For web delivery, converting PNG to WebP often reduces file size more.
