ImageMint's automatic quality search hits 300KB precisely without overshooting. Pair it with a srcset and modern formats for the best of both worlds.

Tips

- Reserve this size for the single most important image on a page, not every thumbnail.
- Combine with lazy loading and async fetchpriority hints for the best performance.
FAQ
Will 300KB slow down my site?
Only if you ship many of them. A single 300KB hero image is fine. Twenty of them is not.
Should I use AVIF at 300KB?
Yes if your audience supports it. AVIF at 300KB produces near-original quality even for very large images.
Is this too big for mobile?
No. 300KB is acceptable on 4G/5G and serves nicely as the largest size in a responsive srcset.
