Got an iPhone? Your photos are probably HEIC — a format half the internet can't read. This tool converts them to PNG and keeps transparency intact, which JPG can't do.

Pick your mode: keep everything in your browser for full privacy, or switch to server mode for a speed boost on large batches. You decide.

The tool handles decoding via the heic-to library, then renders everything to a Canvas for export. Set your own dimensions, DPI, and size targets.

How It Works

No mystery here — here's exactly what happens when you drop your files in.

Choose Browser Mode or Server Mode

Browser mode keeps files on your device. Server mode sends them to our servers for faster handling — files are deleted the moment conversion finishes.

Files stay on your device in Browser Mode
No tracking, no storage, nothing logged
Works offline after the first load

Browser Mode is the private option. Server Mode is the fast one.

Live Preview as Images Load

As soon as you drop a HEIC file, the tool decodes it and shows a preview. No server calls, no waiting. Everything happens in memory.

Your image data never leaves your browser during this step.

Edit Before You Export

Before downloading the final PNG, you can apply changes:

Resize to exact dimensions
Lock or unlock the aspect ratio
Set a custom ratio like 1:1 or 16:9
Choose DPI: 72 for web, 150 for print, 300 for high-quality print
Target a maximum file size

All modifications happen on an HTML5 Canvas that redraws the image pixel by pixel.

Metadata Gets Stripped Automatically

When HEIC files are redrawn onto a Canvas, the original metadata — GPS, camera model, date, lens info — is gone by default.

No GPS coordinates in the output
No camera model exposed
Smaller file, more privacy

One less thing to worry about before sharing photos online.

What You Can Do

More than a format swap.

Transparency is preserved

PNG is the only common format that supports partial transparency (alpha channel). If your HEIC has transparency, the PNG keeps it. This makes PNG essential for logos, icons, and UI elements.

Full resizing control

Set exact pixel dimensions. Lock the aspect ratio to avoid distortion. Or pick a preset ratio — 1:1 for social media, 16:9 for widescreen, 4:3 for standard formats.

Fixed width & heightSet exact pixels for web uploads, app thumbnails, and product images.

Aspect ratio presets1:1 (square), 16:9 (widescreen), 4:3 (standard). Lock to keep proportions, unlock to stretch.

Target file size (rare feature)

Need the output under a specific KB? The tool iteratively reduces dimensions until it hits your target. Useful for email attachments and form uploads.

Works by reducing pixel dimensions — PNG is lossless, so quality stays the same.

DPI control for print

Choose 72 DPI for screens, 150 DPI for decent print, or 300 DPI for professional printing. DPI doesn't change pixel quality — it tells printers how to scale the image.

Handy for designers, photographers, and anyone preparing print materials.

Unlimited batch conversion

Drop as many HEIC files as you want. The tool queues and processes each one without freezing the browser.

One at a time or all at once — no limits.

ZIP download for batches

When you convert multiple files, everything gets bundled into a single ZIP. One click, all your PNGs.

Keeps things organized instead of downloading files one by one.

A Few Things to Know

Honest limits, honest capabilities.

Output is PNG onlyThe converter outputs .png files. No JPG here — that keeps transparency intact and quality loss-free.

No quality slider like JPGPNG is lossless, so there's no quality trade-off — only pixel dimensions. To reduce file size, the tool reduces width/height until the target is met.

Very large files need more RAMBecause everything runs locally, extremely large HEIC files depend on your device's memory. On modern devices this isn't a problem.

Why Keep Conversion in Your Browser?

Most online converters upload your images to a server. That raises questions:

✔️✔ Files never leave your device
✔️✔ No metadata sent anywhere
✔️✔ No server dependency or downtime
✔️✔ Works offline after first load
✔️✔ No signup, no limits, free forever

Who Is This For?

Anyone who needs HEIC to PNG, honestly. But especially:

Photographers migrating from iPhone to Windows or AndroidGraphic designers who need transparent PNG assetsWeb developers who need icons with alpha channelsAnyone preparing images for print or presentations

Common Questions

Will transparency be preserved?

Yes. PNG is the only common image format that keeps partial transparency. If your HEIC has it, the PNG output will too. This matters for logos, icons, and any graphic with see-through areas.

Is there a file size limit?

No hard limit. Your device's memory is the only real cap. For most users, converting hundreds of files in one session works fine.

How do I open the PNG files?

Just double-click them on Windows or Mac and they'll open in your default photo viewer. Or drag them into any design tool, browser, or document.

Can I resize images?

Yes. Set a custom width and height in pixels. Lock the aspect ratio to keep proportions, or unlock to stretch.

Are my files uploaded to a server?

In Browser Mode: never. Everything happens in your browser. In Server Mode: files are uploaded temporarily, converted, and deleted immediately after — no copies are kept.

The Short Version

HEIC doesn't work everywhere. PNG does. This tool converts HEIC to PNG in your browser, keeps transparency intact, strips metadata, and lets you resize or set DPI before downloading. Batch unlimited, ZIP everything, stay private.
