Frequently Asked Questions

How do I convert HEIC photos from my iPhone?

Just drag your HEIC or HEIF files onto the upload area or click to browse. The converter automatically detects the format and recommends JPG as the output. Select your preferred format, adjust quality, and download.

Input formats: HEIC, HEIF, JPG/JPEG, PNG, WebP, GIF, BMP, TIFF, AVIF, and SVG. Output formats: JPG, PNG, WebP, GIF, BMP, AVIF, and TIFF. The auto-detect feature recommends the most compatible output based on your input.

Can I convert multiple images at once?

Yes — drop multiple files at once or select a batch. All images are converted in parallel in your browser. You can download each individually or get them all in a single ZIP file.

Are the original images kept private?

Completely. All conversion happens using the HTML5 Canvas API in your browser. Nothing is uploaded. Your images never leave your device — not even metadata is transmitted.

What output quality should I choose?

For sharing on social media or email, 80–85% quality offers an excellent balance of file size and visual quality. For archival or print use, 95–100% is recommended. PNG and BMP are lossless and ignore the quality setting.
