Frequently Asked Questions
Is my image uploaded to a server?
No. All image conversion happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy.
Which format should I use?
PNG is best for images with transparency or graphics/screenshots. JPEG is ideal for photographs (smaller file size). WebP offers the best compression for web use, supporting both lossy and lossless modes with smaller files than PNG or JPEG.
Is there a file size limit?
There's no hard limit, but very large images (above 50MB) may be slow to process depending on your device. Most images for web use (under 10MB) convert instantly.
