Frequently Asked Questions

Will compressing my JPEG reduce image quality?
JPEG compression involves a quality-size tradeoff. Squezr finds the highest quality setting that meets your target size, preserving as much visual quality as possible.
Can I compress a JPEG to under 100 KB?
Yes! Squezr can compress most JPEGs to very small sizes. If the target is very aggressive, it may also reduce the image dimensions to achieve the size goal.
Is my image uploaded to a server?
No! Squezr processes everything directly in your browser using Web Workers. Your images never leave your device, ensuring complete privacy.
What image formats are supported?
Squezr supports JPEG, PNG, and WebP formats for both input and output. You can convert between formats during compression.
How does the compression work?
Squezr uses a binary search algorithm over quality parameters to find the highest quality that meets your target size. If quality reduction alone isn't enough, it progressively reduces image dimensions.
Is there a file size limit?
Yes, the maximum input file size is 50 MB and the maximum image resolution is 100 megapixels. These limits protect your browser from running out of memory.
Is Squezr free to use?
Yes, Squezr is completely free to use with no watermarks or hidden charges.
