Frequently Asked Questions
The compressor uses your browser's built-in Canvas API to re-encode images at a lower quality setting. This reduces file size while maintaining visual quality. Everything runs locally in your browser — no images are uploaded to any server.
At quality settings of 70-85%, the difference is nearly imperceptible to the human eye while reducing file size by 40-70%. Only at very low quality settings (below 30%) will you notice significant visual degradation.
The compressor supports JPG/JPEG, PNG, and WebP images. PNG images are converted to JPEG or WebP during compression since PNG is a lossless format. You can choose your output format.
There's no hard limit, but very large images (over 50MB) may be slow to process depending on your device. For best performance, we recommend images under 20MB each.
Yes! You can drag and drop or select multiple images at once. Each image will be compressed individually with the same quality setting, and you can download them all.
Absolutely. All processing happens directly in your browser using the HTML5 Canvas API. Your images never leave your device — nothing is uploaded to any server.
