Why this tool is useful
Create a lossless, editor-friendly PNG copy when image fidelity matters more than file size or when a workflow rejects HEIC containers.
Local File Tools · runs locally
Private HEIC to PNG Converter
Convert a dimension-bounded HEIC or HEIF image into lossless PNG pixels inside the browser, with no file sent to YTSave or a third party.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
HEIC decoding uses the unmodified libheif build distributed with heic-to 1.5.2 under LGPL-3.0. License · Corresponding source.
How it works
After strict HEIF brand and ispe dimension checks, the local decoder renders the primary image and the browser encodes a new PNG; embedded source metadata is not copied.
Practical example
Choose a HEIF screenshot or graphic, verify its reported width and height, and save a fresh PNG that can be opened by standard browser and desktop image tools.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
