Frequently Asked Questions
Is my image uploaded to a server?
No. Everything runs entirely in your browser using the Canvas API. Your images never leave your device — 100% private.
What image formats are supported?
You can compress or convert between JPG, PNG, WebP, and AVIF. Input accepts any image format your browser supports, including GIF, BMP, and HEIC on compatible devices.
How much can I compress an image?
Typically 50–90% without visible quality loss for photos at 75–85% quality. PNG files with gradients may compress less. Preview the result before downloading.
Is there a file size limit?
We recommend files under 20MB for best performance. Larger files may be slow to process depending on your device and browser.
Can I resize the image while compressing?
Yes — enter a max width in pixels and the image will be scaled down proportionally before compression. Leave it blank to keep the original dimensions.
