Frequently Asked Questions
Is PDF compression lossless?
Our tool uses advanced compression techniques that can be either lossless or near-lossless. While we optimize file size, the visual quality is preserved to ensure your images look identical to the originals.
Are my files safe and private?
Absolutely! All compression happens locally in your browser. Your files are never uploaded to our servers or transmitted over the internet. This ensures complete privacy and security for your images.
What's the maximum file size?
You can compress files up to 50MB each. For larger files, consider compressing them in smaller batches or using a different format.
How much can I reduce file size?
Compression results vary depending on the image content. Typically, you can expect 30-80% file size reduction. Images with large areas of solid colors compress better than complex photographic images.
