Frequently Asked Questions
- Does compression lose image quality?
- Lossy compression (JPEG) causes slight quality loss, hard to notice by eye. Quality 80-90 balances file size and quality. Lossless compression (PNG optimization) keeps quality but compresses less.
- Why did my image get bigger after compression?
- Already-compressed JPEG may grow due to re-encoding overhead. PNG→JPEG usually shrinks significantly, but JPEG→PNG grows. Choose the right output format.
- Batch compression limit?
- Browser processing depends on device performance and memory. Suggest max 50 images per batch, each under 20MB. For huge batches, split or use desktop tools.
