Tips
- If quality looks too low, increase the target slightly (e.g. 1MB → 150KB)
- Reduce image dimensions first (resize down) — then compress for best results at small sizes
- JPG at 60-70% quality typically hits small size targets with acceptable visual quality
FAQs
What if the image still looks bad at 1MB?
Lower the quality target slightly and try again. For very small targets, some quality loss is inevitable.
Does compression change image dimensions?
No — compression reduces file size without changing pixel dimensions. Use resize to change dimensions.
Can I compress to exactly 1MB?
The tool targets under 1MB. The actual output may be slightly smaller than 1MB.
