Best Image Compression Settings for JPG, PNG, and WebP
Learn when to use JPG, PNG, or WebP and how to reduce file size without over-compressing screenshots, UI assets, or web images.
Compression settings are rarely one-size-fits-all. A product screenshot, a transparent UI icon, and a landing page hero image all need different tradeoffs.
The fastest way to improve site speed is often not more code optimization, but smaller visual assets exported with the right format.
Choosing the right format
Use JPG for photographic content, PNG for transparency-sensitive graphics, and WebP when you want a strong size-to-quality balance for the web.
The format choice usually matters more than small quality slider changes.
What to compress aggressively
Screenshots in docs, support replies, internal decks, and bug tickets can often be compressed more than marketing visuals.
Public-facing hero images deserve more visual care because artifacts will be more noticeable at larger sizes.
Aggressive: docs screenshots, tickets, drafts
Moderate: blog images, UI previews
Careful: homepage hero visuals, branding
How to review output properly
Do not only compare file size. Zoom in on text edges, gradients, and small UI details. Compression artifacts usually show up there first.
If transparency matters, avoid exporting to JPG just because it seems smaller.
