Frequently Asked Questions
How can I compress an image without uploading to a server?
Our tool runs entirely in your browser using the Canvas API. Upload your image, adjust the quality slider, and download the compressed result — nothing ever leaves your device. No server, no upload, no privacy risk.
How much can I reduce image file size without losing quality?
Most images compress by 50-80% with no visible quality loss. Higher quality settings (90-100%) preserve more detail. Lower settings (30-60%) create smaller files with minimal visible difference for most photos.
What image formats are supported?
The tool supports JPEG, PNG, and WebP formats. You can convert between these formats during the compression process. WebP typically offers the best compression ratio.
Is there a file size limit?
There are no strict file size limits. Very large images (50MP+) may be limited by your browser's available memory. For most use cases, there are no practical limits.
Is my image data private?
Absolutely. All processing happens locally in your browser using the Canvas API. Your images are never uploaded to any server, ensuring complete privacy.
