Frequently Asked Questions
- How much can I compress an image without losing quality?
- JPG images can typically be compressed to 60–80% quality with no visible difference, achieving 40–70% file size reduction. PNG files benefit from lossless compression that removes metadata without changing any pixel. The best level depends on the image — our tool previews the result before you download.
- What is the difference between lossless and lossy compression?
- Lossless compression removes metadata and optimizes encoding without changing any pixel — the compressed image is pixel-perfect identical to the original at a smaller file size. Lossy compression discards fine detail to achieve much smaller sizes. JPG always uses lossy; PNG uses lossless; WebP supports both.
- Does compressing an image change its dimensions?
- No — image compression reduces file size but does not change the pixel dimensions (width × height) or DPI. A 2000×1500 image remains 2000×1500 pixels after compression. If you also need to resize, use the Image Resizer tool separately.
- Which image format compresses best for websites?
- WebP gives the best compression for web use — typically 25–35% smaller than an equivalent JPG at the same visual quality, with broad browser support. For photos, use WebP or compressed JPG. For graphics with transparency, use WebP or optimized PNG. AVIF is even more efficient but has slightly lower browser support.
