HEIC stores high-efficiency photos and image sequences in an ISO base media container.
PDF preserves a fixed page layout across devices and operating systems.
HEIC pixels are decoded locally and embedded as lossless PNG image data.
Each decodable image becomes one PDF page, up to ten images and 50 megapixels in total.
Source metadata and high bit depth are not preserved in the PDF.
Choose one HEIC file, then select automatic, A4, or US Letter pages with portrait, landscape, and margin controls. Each decodable image in the container becomes a page.
One HEIC file can contain up to ten decodable images and 50 megapixels in total. The input limit is 25 MB.
The browser decodes the HEIC pixels, encodes lossless PNG image data, and embeds each result into a new PDF on this device. Files chosen from your device are not uploaded, and PWRKIT does not retain an input or output copy. Analytics records the format, size bucket, duration, and result class, never the filename or file content.
When you import from a URL, the application fetches only a validated public HTTP or HTTPS address, checks the downloaded file in memory, and relays it to this browser. The file is not written to disk or the database, and its URL is not sent to analytics.
