Q：Does this tool support converting iPhone HEIC to JPG, WebP to JPG, BMP to JPG, PNG to JPG, and GIF to PNG?

A：Yes, all these conversions are supported.Additional formats are also available: BMP‑to‑PNG, BMP‑to‑WebP, PNG‑to‑BMP, PNG‑to‑WebP, GIF‑to‑BMP, GIF‑to‑JPG, GIF‑to‑WebP, JPG‑to‑BMP, JPG‑to‑PNG, JPG‑to‑WebP, WebP‑to‑BMP, WebP‑to‑PNG.

Q：Will there be any quality loss when converting HEIC to JPG or doing other format conversions?

Outputs in PNG and BMP have nearly invisible quality degradation. The default quality value is set to 1 for maximum image quality, which works perfectly for everyday use.

Q：What is the maximum image size for uploads?

A：The longest side of your image can be up to 7000 pixels. If either side exceeds 7000 px, the image will be automatically resized proportionally to prevent browser‑rendering issues.

Q：Is there a limit on the number of files for batch conversion?

A：Yes. We recommend uploading no more than 100 files per batch. If you have more than 100 images, please split them into multiple batches.（Note: The actual processing limit depends on your device’s memory and performance. You may adjust the number of files based on your device condition.）

Q：Will transparent PNG images get a black background when converted to JPG?

A：No. Compatibility optimizations are built‑in. Transparent areas will be filled with a solid white background on the canvas.

Q：Will photo metadata be kept after image format conversion?

A：No. This tool runs purely inside your browser using Canvas. None of the original photo metadata will be preserved.

Q：Can the tool auto‑rotate JPG and HEIC photos to the correct orientation?

A：Yes. It automatically fixes rotation for JPG and HEIC photos with EXIF Orientation tags from 2‑8.However, many screenshots, AI‑generated images, and re‑saved edited photos do not contain EXIF orientation data. If this tag is missing or corrupted, images will be output in their original pixel orientation.

Q：Can GIF files be converted into multiple separate images of other formats?

A：No. Only the first frame of a GIF will be converted to your target format.

Can converted images be further edited with editing software such as AI tools and Photoshop?

A：Partial support. Exported JPG, PNG, BMP and WebP files work well with Adobe Photoshop for further editing. JPG and PNG files are compatible with Adobe Illustrator. Other formats are not supported.

Q：Can I batch‑convert multiple different image formats into one single target format? ？
