How to Compress Images Without Losing Quality
Why image compression matters
Large images are the single biggest cause of slow websites. A page that takes 4 seconds to load loses 25% of its visitors before they see anything. Compressing your images can cut page weight by 60-80% with no visible difference to the human eye.

Lossy compression permanently removes image data. At quality 80-85%, the results are visually identical to the original but 60-70% smaller. This is the right choice for web images.
Lossless compression removes metadata and optimises encoding without losing a single pixel. File sizes reduce by 20-30%. Use this for images that need to remain pixel-perfect, such as product screenshots or medical imagery.
The best settings for web images
- JPG quality 80-85% — visually identical to 100%, typically 60% smaller
- WebP quality 80% — smaller still than JPG 85%, excellent browser support
- PNG — use lossless compression only; lossy PNG looks noticeably degraded
How to compress in bulk
The TARUMAK Image Compressor lets you drag in multiple images at once and download them all compressed. It runs in your browser — your images never leave your device.
Convert to WebP for maximum savings
If you convert JPG or PNG images to WebP before compressing, you get an additional 25-35% reduction in file size. Use the JPG to WebP converter and then apply compression.
Remove EXIF data too
Photos taken on a smartphone contain hidden EXIF metadata — GPS coordinates, camera model, shutter speed. This can add 50-100KB to an image. Use the EXIF Data Remover to strip it out, which also protects your privacy.
What quality setting should I use?
Start at 80% and compare with the original. If you cannot spot the difference, use 80%. If you can, try 85%. Going above 90% gives almost no visual benefit but significantly increases file size.
Should I compress PNG files?
Only with lossless compression. Lossy PNG compression causes visible colour banding on flat-colour images like logos and screenshots. Convert PNG to WebP instead for the best size-to-quality ratio.
