How to Compress Images Without Losing Quality
Compress JPG, PNG, and WebP images with no visible quality loss. Target-size compression, format tips, and the settings that actually matter.
The best compression is invisible: the file gets smaller, but your eyes can't tell. Achieving that takes the right format, the right quality setting, and — in most cases — a good target-size algorithm.
Why images are so big
A modern phone shoots 12 MP photos in the 3–6 MB range. Uploading them at native size wastes bandwidth and slows every page. Most photos can be compressed to 100–300 KB with no visible loss.
Pick the right format first
- Photos → JPG or WebP.
- Graphics, logos, screenshots → PNG or WebP lossless.
- Modern web → AVIF for maximum savings.
The quality slider explained
For JPG and WebP, quality 82–90 is the sweet spot. Below 70 you start seeing block artifacts around edges. Above 95, the file grows quickly for no visible gain.
Target-size compression
If a form or platform requires an image under, say, 200 KB, don't guess the quality. Use target-size mode — the tool binary-searches for the highest quality that fits the size.
Step-by-step
- Open the compressor and drop your image.
- Pick quality mode or target-size mode.
- Preview before/after side-by-side.
- Download the compressed file.
