Frequently Asked Questions
Is my image quality affected by JPEG compression?
JPEG is a lossy format. However, our local compressor lets you adjust the quality parameter (typically 70-80% is optimal), giving you full control over the visual-quality-to-file-size ratio before saving.
Can I use this tool to optimize photos containing personal IDs?
Yes. Since all computation takes place in your local memory, this is the safest way to compress sensitive files (e.g. photos of passports, driver's licenses) without risking identity theft.
