Frequently Asked Questions
- Should I convert HEIC to PNG or JPG?
- Use PNG if you need lossless quality, plan to edit the image further, or need transparency. Use JPG if you need smaller files for sharing, email, or web use. For photos shared on social media or via email, JPG is usually the right choice.
- Will converting HEIC to PNG lose quality?
- No. PNG is lossless — your image will look pixel-perfect identical to the original HEIC. Unlike JPG, PNG never discards image data during compression.
- Why is my PNG file larger than the original HEIC?
- HEIC uses lossy compression to achieve small file sizes. PNG uses lossless compression, which preserves every pixel but produces larger files. A 2MB HEIC photo may become an 8-15MB PNG.
- Does HEIC support transparency?
- HEIC technically supports alpha channel transparency, but iPhone camera photos never contain transparency. If you have an HEIC file with transparency, Convertify preserves it in the PNG output.
- Can I convert multiple HEIC files to PNG at once?
- Yes. Convertify supports batch conversion — upload up to 10 HEIC files and download them all as PNG simultaneously.
- Is PNG better than JPG for editing?
- Yes. PNG is lossless — you can edit and re-save without quality degradation. JPG loses a small amount of quality each time it is re-encoded. Use PNG for any image you plan to edit multiple times.
- How do I stop iPhone from saving photos as HEIC?
- Go to Settings → Camera → Formats → Most Compatible. Your iPhone will save photos as JPG going forward. Existing HEIC photos are not affected.
- Does PNG support transparency?
- Yes. PNG supports full 8-bit alpha channel transparency. This is one of the main advantages of PNG over JPG for graphics, logos, and design assets.
Why PNG instead of JPG for HEIC conversion?
Most people default to JPG when converting HEIC photos, but PNG is often the better choice. PNG uses lossless compression — every pixel is stored exactly as it was captured. If you're editing photos, creating graphics, or working with images that have text or sharp lines, PNG preserves every detail without compression artifacts. The tradeoff is file size: PNG files are larger than JPG. But for logos, screenshots, diagrams, and images you plan to edit further, PNG's lossless quality is worth it.
What is HEIC and why does iPhone use it?
Apple introduced HEIC (High Efficiency Image Coding) with iOS 11 in 2017 as a replacement for JPEG. Using the HEVC codec, HEIC compresses photos to roughly half the file size of equivalent JPEG images with no visible quality loss. This is why a typical iPhone library of 1,000 photos takes up far less space than it would on a camera that shoots JPEG. The problem is that HEIC is an Apple-centric format — while it's excellent for on-device storage, it creates friction the moment you try to share, edit, or upload photos outside the Apple ecosystem.
PNG vs JPG for HEIC conversion — choosing the right output
| Use case | PNG output | JPG output |
|---|---|---|
| Editing in Photoshop | ✅ Recommended | ⚠️ Quality loss on re-save |
| Sharing photos | ⚠️ Large files | ✅ Smaller files |
| Screenshots with text | ✅ Sharp text | ❌ Compression artifacts |
| Product photos | ✅ No background loss | ⚠️ Background artifacts |
| Web use | ⚠️ Slower load | ✅ Fast load |
| Social media upload | ✅ Accepted | ✅ Accepted |
| Preserving transparency | ✅ Full alpha | ❌ No transparency |
HEIC transparency — does it carry over to PNG?
HEIC technically supports alpha channel transparency via the HEIF container format. In practice, iPhone photos never contain transparency — the camera always captures a full rectangular image. However, if you have an HEIC file with transparency (created by apps, not the camera), Convertify preserves it in the PNG output. PNG supports full 8-bit alpha channel transparency, which is more capable than HEIC's transparency implementation. This makes HEIC-to-PNG conversion ideal for design assets and edited photos that contain transparent elements.
PNG file size — what to expect after converting HEIC
PNG files are larger than both HEIC and JPG. A typical iPhone photo at 12MP that is 2MB as HEIC will become approximately 8-15MB as PNG (lossless) or 3-6MB as JPG. The exact size depends on image complexity — photos with many colors and details produce larger PNG files, while screenshots and graphics with flat colors compress very efficiently. If file size is a concern, consider JPG for photos and PNG for graphics, screenshots, and anything requiring transparency or future editing.
How to convert HEIC to PNG on iPhone, Windows, and Mac
On iPhone: The simplest approach is to change the camera format to Most Compatible (Settings → Camera → Formats) for future photos. For existing HEIC photos, AirDrop to a Mac and export from Preview as PNG, or use Convertify on any device. On Windows: Windows 11 with the HEIF Image Extensions codec can open HEIC files. To save as PNG, open in Photos app → Edit → Save a copy. Without the codec, use Convertify — upload HEIC, download PNG, no software needed. On Mac: Open the HEIC file in Preview → File → Export → choose PNG format. For batch conversion of many files, Automator or Convertify handle multiple files simultaneously.
Lossless quality — the key advantage of PNG over JPG
Every time you save a JPG file, quality degrades slightly — this is called generation loss. If you save the same JPG ten times (editing, saving, re-editing), the accumulated quality loss becomes visible. PNG has zero generation loss. You can edit and re-save a PNG file hundreds of times with absolutely no quality degradation. This makes PNG the professional choice for any image that will be edited, layered, or re-saved multiple times. For archiving important HEIC photos that you want to edit later, converting to PNG rather than JPG preserves maximum quality through the entire editing workflow.
How Convertify converts HEIC to PNG
Convertify uses libvips with a Rust backend to handle HEIC decoding and PNG encoding. libvips processes images in streaming pipelines, which means large HEIC files from 48MP or 50MP iPhone Pro cameras are handled efficiently without loading the entire image into memory. Color profiles embedded in HEIC files are preserved and applied during PNG encoding. EXIF metadata including GPS coordinates, capture time, and camera settings is retained in the PNG output. Your file is processed server-side over an encrypted connection and deleted immediately after download.
