Frequently asked questions
Will compressing to 1MB ruin my photo's quality?
Usually, no. 1MB is still a very generous size for web images and standard document uploads. Our tool uses a smart iterative algorithm that preserves as much quality as possible while strictly meeting the 1MB target.
Is this tool safe for sensitive documents like ID cards?
Yes, it is completely safe. This tool operates 100% locally in your web browser. Your images are never uploaded to any server, making it perfect for sensitive IDs, documents, and personal photos.
What happens if my image is already under 1MB?
If your image is already under the target size, the tool will still optimize the format and ensure it is ready for upload, but it will not unnecessarily reduce the quality.
Can I process multiple images at once?
Currently, this specific tool is designed for single-image, high-precision processing. For bulk processing, please check our generic image compressor options.
