Frequently Asked Questions
Is my image data secure?
Yes! All conversion happens entirely in your browser using the Canvas API. Your images are never uploaded to any server.
Can I convert HEIC files from my iPhone?
Yes! HEIC and HEIF formats are supported. The tool uses a specialized decoder to convert them to your chosen format.
Which format should I choose?
Use WebP for best compression on the web, JPEG for photos, PNG for images needing transparency, and GIF for simple animations or graphics.
Does the quality slider affect PNG and BMP?
No. PNG and BMP are lossless formats, so the quality slider only appears for JPEG and WebP conversions.
Is there a file size limit?
The tool handles files up to 50MB each. Since processing happens in your browser, very large files may take longer depending on your device.
