HEIC to PNG Converter – Free, Private, and 100% Browser-Based (No Upload Required)
Modern iPhones and Apple devices save photos in the HEIC format, a highly efficient image type that offers excellent quality at a reduced file size. While HEIC is great for storage, it is still not universally compatible with many desktop programs, older devices, design tools, and various websites. As a result, users often need a simple and reliable way to convert HEIC to PNG.
Our HEIC to PNG Converter is designed to solve this problem with a privacy-first, instant, and fully browser-based solution. Unlike traditional converters, this tool performs the entire conversion inside your device — meaning your files never leave your browser.
Whether you need a single image or hundreds, the tool handles everything efficiently, securely, and without compression loss. In this article, we’ll explain how the conversion works, what makes this tool unique, and why it is one of the best HEIC-to-PNG converters available online.
How Our HEIC to PNG Conversion Works (Fully Client-Side)
The most important thing to understand about this converter is that it operates 100% client-side, using the heic-to library. This means all processing occurs inside the user’s browser, not on a remote server. No uploading. No storage. No risk. Here’s a breakdown of the internal workflow:
1. Instant Preparation & Live Preview
When the user drags a HEIC file into the tool, the converter immediately processes it in memory and generates a PNG Blob. This allows the interface to display a live preview instantly. There is no waiting, no external server calls, and no visual quality loss. Everything happens locally.
2. Modify Your Image Before Final Conversion
Before downloading the final PNG, users can apply advanced modifications:
- Resize dimensions
- Lock or unlock aspect ratio
- Set a custom aspect ratio
- Control DPI for printing
- Reduce file size by targeting a maximum size
3. Final PNG Generation
Once the user clicks Convert, the tool applies the selected modifications and generates the final PNG file. Since the output is produced via Canvas rendering, the result is a clean, accurate PNG with transparency preserved.
4. Automatic Metadata Stripping (Built-In Privacy Protection)
When HEIC files are redrawn onto a Canvas, all original metadata — including GPS coordinates, camera model, shooting conditions, date/time, and other EXIF fields — is automatically removed. This makes your final PNG:
- Private
- Safe to share
- Free from unnecessary embedded information
Key Features of the HEIC to PNG Converter
This tool provides more than a simple format change. It includes advanced controls normally found in professional image editors — but in a fast and user-friendly interface.
1. Supports and Preserves Transparency
PNG is ideal for graphics, logos, and UI assets because it supports alpha transparency. This converter ensures transparency is preserved during conversion, something that JPG cannot do. If you're converting photos for design, thumbnails, or app development, this is a crucial benefit.
2. Advanced Resizing Options
The tool gives users full control over output dimensions.
3. Target File Size — A Rare and Powerful Feature
One unique capability of this converter is allowing users to specify a maximum output file size (e.g., under 500KB). Since PNG is a lossless format, it doesn’t support adjustable compression like JPG. Instead, the tool:
- Checks the file size
- Reduces image dimensions iteratively
- Re-checks until it meets the target size
This ensures the user gets the smallest possible file without introducing compression artifacts. Ideal for: Email attachments, Website image weight optimization, Complying with upload limits on forms, Reducing PNG icons for apps
4. DPI Control for Printing & Design
The converter allows users to choose from three DPI settings:
- 72 DPI – Best for screens & web
- 150 DPI – Medium-quality printing
- 300 DPI – Professional printing
DPI does not change pixel quality directly but impacts how printers interpret the image. This is especially useful for: Designers, Photographers, Students preparing print assignments, Businesses creating flyers or documents
5. Batch Processing — Convert Unlimited HEIC Files at Once
Unlike many online tools with upload limits, this converter supports unlimited batch processing. The tool: Queues each file, Converts them one by one, Ensures smooth performance, Avoids memory overload. This is extremely valuable for: Photographers with iPhone photo sets, Teams converting design assets, Users migrating from Apple devices to Windows
6. Batch Download as ZIP
After conversion, users can download all PNGs at once inside a single ZIP file. This reduces clutter and streamlines downloading, especially for large sets of images.
Technical Details & Limitations
To maintain quality, privacy, and stability, here are some important notes:
