Compress Images Without Destroying Quality
Format, dimensions, and quality matter more than one “compress” button.
What it does and when to use it
File size depends on pixel count, format, and compression. Reducing dimensions often saves more than a small quality change.
What information to enter
Check the actual display size, transparency needs, and whether the image is a photo, logo, or screenshot.
How to understand the result
JPEG often suits photos, PNG suits transparency and sharp graphics, and WebP can balance web quality and size.
Recommended step-by-step workflow
- Check the assumptionsFile size depends on pixel count, format, and compression. Reducing dimensions often saves more than a small quality change.
- Use matching unitsCheck the actual display size, transparency needs, and whether the image is a photo, logo, or screenshot.
- Compare with another scenarioJPEG often suits photos, PNG suits transparency and sharp graphics, and WebP can balance web quality and size.
Short example
A 4,000-pixel-wide image displayed at 1,200 pixels can be reduced substantially before changing quality.
Common mistakes
- Recompressing an already compressed JPEG repeatedly.
- Converting a transparent logo to JPEG and losing transparency.
