Compress Images for the Web
Images are over half the weight of a typical web page — and heavy images slow load times, hurt Core Web Vitals, and cost you rankings. Compress and convert to modern formats before you upload, all in your browser.

Which format should you use for the web in 2026?
| Format | Best for | Size vs JPEG |
|---|---|---|
| JPEG | Photos, broad compatibility | baseline |
| PNG | Logos, transparency, sharp edges | larger |
| WebP | Almost everything on modern web | ~25–35% smaller |
| AVIF | Maximum compression, modern browsers | ~50% smaller |
For most sites in 2026, serve WebP as the default and AVIF where you can, with a JPEG fallback for older browsers.
How to compress an image for the web
- Drop your images into PressImg.
- Convert to WebP or AVIF (or keep JPEG/PNG and just compress).
- Set quality — around 80 is the sweet spot for web: big savings, no visible loss.
- Optionally resize to the max width you actually display (e.g. 1920px).
- Compress and download — one file or the whole batch as a ZIP.
Why compress before uploading?
Every kilobyte you cut is faster load time and a better Core Web Vitals score, which Google uses in ranking. Compressing locally also means your images never touch a server — nothing is uploaded, so client work and unreleased assets stay private.
