Why Convert HEIC to PNG?
HEIC is Apple's space-efficient photo format, but it creates problems outside the Apple ecosystem and in professional editing workflows. Many design tools (especially older versions) cannot import HEIC directly. Even when software supports HEIC, converting to PNG before editing ensures you start from a lossless baseline — every subsequent save maintains the exact pixel data, avoiding the generation loss that occurs with lossy format re-saves.
PNG is also essential when you need to add transparency to your iPhone photos. Want to remove the background from a portrait shot? Cut out a product image for a composite? The workflow starts with converting to PNG, which supports full 8-bit alpha channel transparency. Once in PNG format, you can use ToolPix's Background Remover or any other tool to add transparency and maintain it through subsequent edits.

Benefits of Using ToolPix HEIC to PNG Converter
Lossless Editing Baseline
PNG's lossless compression ensures no further quality loss when you open, edit, and resave the image in your editing software.
Transparency Ready
Once in PNG format, you can add transparency using background removal tools — essential for design and compositing workflows.
Universal Editor Support
Every image editor from Paint to Photoshop handles PNG perfectly — no HEIC codecs or plugins needed.
Private and Instant
The conversion happens locally in your browser. Your personal iPhone photos are never uploaded to any server.
Common Use Cases
- •Preparing iPhone photos for editing in Photoshop, GIMP, Figma, or other design tools
- •Converting HEIC photos as a first step before background removal to create transparent PNGs
- •Creating print-ready versions of iPhone photos in a universally accepted lossless format
- •Archiving iPhone photos in a format that is accessible on any operating system
- •Using iPhone photos in web design projects where PNG is the required format
Technical Details: HEIC vs PNG
HEIC stores image data using HEVC (H.265) lossy compression, producing files approximately 50% smaller than JPG at equivalent quality. The format supports features like depth maps, Live Photos, and HDR metadata within a container based on the ISOBMFF (ISO Base Media File Format). PNG uses lossless DEFLATE compression that preserves every decoded pixel exactly. When converting HEIC to PNG, the HEVC-compressed data is decoded to raw RGB pixels, and then re-encoded losslessly using PNG compression. The resulting PNG is significantly larger than the HEIC source (because lossless compression cannot match lossy efficiency) but preserves the exact decoded pixel values for editing purposes. HDR metadata is tone-mapped to standard dynamic range during the conversion.
About HEIC to PNG Conversion
Need to edit your iPhone photos in a professional image editor or use them in a design project? Converting HEIC to PNG gives you a lossless, universally compatible file that preserves the decoded image quality and supports transparency. While JPG conversion is fine for casual sharing, PNG is the better choice when you plan to edit the image further — the lossless compression ensures no additional quality loss through the editing process.
ToolPix converts your HEIC photos to PNG entirely in your browser. No server uploads, no privacy concerns, no software installation. The process is instant and the resulting PNG file works in every image editor, design tool, and operating system.
Frequently Asked Questions
Should I convert to PNG or JPG?
Convert to PNG if you plan to edit the image further or need transparency. Convert to JPG if you simply want to share the photo — JPG files are smaller and more convenient for casual use. For archival purposes, PNG is the better choice as it is lossless.
Will the PNG file be much larger than the HEIC?
Yes. HEIC's lossy compression produces very small files (a 12 MP iPhone photo is about 1-3 MB in HEIC). The same image as PNG can be 10-20 MB because PNG stores every pixel losslessly. This is the trade-off for lossless quality and editing flexibility.
Does the conversion preserve the full quality of the HEIC photo?
The conversion preserves the decoded pixel data exactly — every pixel in the PNG matches the decoded HEIC image. However, the original uncompressed sensor data (before HEIC encoding) cannot be recovered. The PNG is a lossless snapshot of the HEIC's decoded output.
