Frequently Asked Questions
How does the compression work?
This tool uses the browser's built-in Canvas API to re-encode images at your chosen quality level. For WebP and JPEG, lowering quality reduces file size significantly. PNG is lossless but can still benefit from resizing.
Is my image uploaded to a server?
No. Everything happens 100% locally in your browser using JavaScript. Your images are never sent to any server. This is fundamentally more private than most online compressors.
Which format gives the smallest files?
WebP generally produces the smallest files at the same visual quality, often 25–35% smaller than JPEG. For photos, WebP at 75–80% quality is the sweet spot. PNG is best for images with transparency or sharp edges.
Can I set a maximum file size?
Yes! Use the "Max file size" option. The tool will automatically reduce quality until the output fits within your target. Great for meeting upload limits on social media or email.
Does it preserve EXIF data?
No, EXIF metadata (camera info, GPS location) is stripped during compression. This is actually a privacy benefit — no hidden data in your compressed images.
What's the maximum image size?
You can upload images up to 20 MB each. Very large images (over 4000px) may take a moment to process depending on your device.
