Frequently Asked Questions
Does ImageCrush upload my images to a server?
No. All processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device — there are no uploads, no servers, and no privacy concerns whatsoever.
How much can I compress an image without losing quality?
For JPEG and WEBP, a quality setting of 75–85% typically reduces file size by 60–80% with no visible quality loss. PNG is lossless, so size savings come from removing metadata.
What image formats are supported?
You can upload JPG, PNG, WEBP, GIF, and BMP. Export as JPEG, PNG, or WEBP. WEBP gives the smallest file size at equivalent quality and is recommended for web use.
Can I resize to any custom dimension?
Yes. Type any pixel dimensions in the Pixels tab, scale by percentage in the Percentage tab, or pick from popular presets like 4K, 1080p, social media sizes, and icons.
Is ImageCrush really free with no watermarks?
Completely free, unlimited images, no account required. No watermarks are ever added. Your output file is exactly what you see in the preview.
