How to compress images (WebP/JPG/PNG)
Reduce file size without uploading files. Pick the right format, choose a sensible quality, and optionally downscale.
Quick defaults (most cases)
- Photos: WebP at 80% quality.
- Maximum compatibility: JPG at 80–90% quality.
- Logos/text/transparent UI: PNG (or WebP if supported).
- If files are still large: reduce dimensions (max width/height).
How to choose quality
- 80%: great starting point for most photos.
- 90–95%: fewer artifacts, larger files.
- 60–75%: much smaller files, artifacts may show.
- Always check faces/text edges after compressing.
FAQ
What quality should I use for WebP/JPG?
Start at 80%. If you see artifacts, increase to 90–95%. If you need smaller files, try 60–75%.
Should I use WebP or JPG?
Use WebP for the smallest photo files. Use JPG if you need maximum compatibility.
Why doesn’t PNG get much smaller?
PNG is lossless. For photos, use WebP/JPG. For PNG, reduce dimensions to shrink file size.
Do you upload my images?
No. Compression runs locally in your browser.
