HEIC to JPG / PNG — Step-by-Step Guide
Learn how to use HEIC to JPG / PNG: step-by-step instructions, settings, export options, privacy, limits and troubleshooting.
Open HEIC to JPG / PNGStep-by-step instructions
- Choose up to five HEIC or HEIF files and wait for local inspection.
- Check the number of still pictures detected in the batch.
- Choose JPG or PNG and, for JPG, set the quality percentage.
- Click Convert HEIC images and wait for local conversion.
- Download the image or numbered ZIP before leaving the page.
Picture preservation and format support
Every top-level still picture returned by the HEIC decoder is exported; multi-picture inputs are never silently reduced to the first image. Thumbnails and auxiliary depth or gain-map data are not separate exported photos. HEIF sequences, AVIF and Live Photo video tracks are not supported.
JPEG is useful for smaller photo files and uses a white background for transparent pixels. PNG preserves transparency. Converted files are ordinary 8-bit images; HDR appearance may change, and camera metadata is removed. JPEG quality changes compression, while PNG ignores the JPEG quality control.
Local decoding and device limits
An approximately 15 MB self-hosted WebAssembly decoder is loaded when needed. Decoding runs in a worker with a timeout, memory limits and cancellation. Source dimensions and picture counts are checked before full raster decoding.
Each file is limited to 10 MB and eight pictures. Each picture is limited to 16 megapixels and 4096 pixels per side; the entire selected batch is limited to 32 million picture pixels. The combined compressed input limit is 24 MB. Smaller batches work better on phones.
Processing and privacy
Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation. Previewing and editing do not use an operation. Daily allowances reset at 00:00 UTC. Downloads of an already-created result do not count again.
If an operation cannot finish
Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.
If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.
Check the current limits
Allowances and per-operation limits can change. The HEIC to JPG / PNG page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
