FileOnTap announced the release of a free browser-based HEIC converter that transforms HEIC photos into JPG, PNG and PDF formats without transmitting the images to a remote server. All conversion work takes place locally inside the user's web browser, so the original photos never leave the device during the process.

HEIC, short for High Efficiency Image Container, is the default photo format on many Apple devices and is used by a growing number of Android handsets. While the format offers efficient compression, compatibility remains inconsistent: many older applications, web services and printing workflows still do not recognize HEIC files. The new converter addresses that gap by producing widely supported output formats directly on the user's machine.

The release includes a dedicated HEIC to PDF converter (https://fileontap.com/heic-to-pdf/) for producing portable documents suitable for sharing, printing or archiving multiple images, alongside companion tools for HEIC to JPG and HEIC to PNG conversion. Because conversion is handled client-side, the tools continue to function on slow or limited internet connections, and performance depends on the user's device rather than on server capacity.

The local-processing design was chosen to address privacy concerns associated with conventional online converters, which typically require users to upload personal photos to a third-party server before conversion. "Most online converters require you to send your photos to a server, which means your personal images leave your control and may be stored or logged," said Shao Zheng, developer of FileOnTap. "We built these tools so that the conversion happens in the browser, on the user's own device. That way, a photo of a passport, a medical document or a family moment never has to be uploaded anywhere."

The converter supports batch processing of multiple HEIC images into a single PDF document, a workflow aimed at users who need to share, print or archive photos from smartphones. The JPG and PNG options target users who need to open or edit HEIC photos in applications that do not support the format. No account, software installation or watermark is involved in the workflow.
