Frequently Asked Questions
How much can I compress my image?
The amount of compression depends on the image type and your quality setting. JPG and WebP images can typically be reduced by 40-80% at a quality of 70-80%. PNG compression through this tool re-encodes the image, which may yield modest savings. Use the quality slider to find the best balance for your needs.
Will image compression reduce quality?
Yes, lossy compression (used for JPG and WebP) reduces quality to achieve smaller file sizes. However, at the default 80% quality setting, the visual difference is barely noticeable for most photos. You can adjust the slider to preview the trade-off between quality and file size.
How does PNG compression work in this tool?
PNG uses lossless compression, which means it cannot be further compressed without quality loss using the PNG format alone. This tool re-encodes PNG images through the Canvas API, which may produce a slightly different (sometimes smaller) file. For significant PNG size reductions, consider converting to WebP or JPG instead.
What is the maximum file size I can compress?
You can compress images up to 50 MB in size. The compression runs in your browser, so very large images may take a moment depending on your device. Most images compress in under a second.
Can I compress multiple images at once?
Currently, this tool compresses one image at a time. You can compress images back-to-back quickly — each one typically takes less than a second. This allows you to fine-tune the quality setting for each image individually.
Is my image uploaded to a server?
No. All compression happens locally in your browser using the HTML5 Canvas API. Your images never leave your device. There is no upload, no account required, and no data collection of any kind.
