Frequently Asked Questions

How does image compression work?▾
Our tool uses your browser's Canvas API to re-encode images at the quality level you choose. For JPEG images, lower quality means smaller files with minimal visual difference. For PNG images, the tool optimizes the encoding. No data is uploaded to any server.
Is my image uploaded to a server?▾
No. All processing happens entirely in your browser using JavaScript. Your images never leave your device.
What formats are supported?▾
PNG, JPEG, WebP, and most browser-supported image formats. The output format can be selected in the options.
How much can I reduce the file size?▾
Typical JPEG compression at 75% quality can reduce file size by 60-80% with minimal visible quality loss. Results vary depending on the image content and original format.
Does this tool work on mobile devices?▾
Yes. The compressor runs entirely in your browser and works on any device with a modern browser, including phones and tablets.
Can I compress multiple images at once?▾
Currently the tool processes one image at a time. Upload each image separately to compress it with your preferred quality setting.
What quality setting should I use?▾
For web images, 70-80% quality offers the best balance of file size and visual quality. For print or high-fidelity use, stay at 90% or above. Below 50% you may notice visible artifacts.
