What is the PNG output format?

PNG (Portable Network Graphics) is a lossless raster image format that supports full 24-bit color and an alpha transparency channel. Unlike JPEG, PNG compression is lossless — every pixel from the cropped HEIC region is preserved exactly at full quality. PNG is the standard format for web graphics, UI assets, design tool imports, and any workflow requiring pixel-perfect fidelity.

Can I crop the HEIC image before converting to PNG?

Yes — the tool provides an interactive crop overlay on the source image. Drag the corner and edge handles to define exactly which portion of the HEIC photo you want in the output PNG. Click Preview Crop to see the result before downloading.

Does my image get uploaded to a server?

No. All processing — loading, HEIC decoding, cropping, and PNG encoding — happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your image never leaves your device.

Is PNG the right output format for my use case?

PNG is ideal when you need lossless quality — product photos for editing, screenshots, UI assets, transparency support, or any workflow where re-editing the file later is likely. If file size is the priority and lossy quality is acceptable, HEIC to JPG Crop may produce a smaller file. For modern web delivery, consider HEIC to WebP Crop or HEIC to AVIF Crop for smaller lossless-quality files.

How does HEIC decoding work in the browser?

The tool first tries native browser HEIC support (available in Chrome 105+, Safari, and Edge). If native support is unavailable, it automatically falls back to the heic2any JavaScript library for full cross-browser compatibility. Either way, the decoded image is drawn to a Canvas and ready for cropping.

How do I reset and convert a different image?

Click the Start Over button that appears after loading an image. This clears the current file and resets the crop area so you can load a new HEIC photo.

Load a HEIC photo, drag the crop handles to define exactly the area you need, preview the result, then download a lossless PNG file. Every pixel from the selected crop region is preserved at full quality. Everything runs in your browser — your image never leaves your device.

What This Tool Does

This tool loads a HEIC or HEIF image directly in your browser, decoding it using native browser support (Chrome 105+, Safari, Edge) or the heic2any JavaScript library as a fallback for full cross-browser compatibility. It presents an interactive crop overlay with draggable handles, and converts the selected area to a lossless PNG file. No server upload is required. The full workflow — loading, HEIC decoding, cropping, and PNG encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. The output PNG captures every pixel of the cropped region at full original HEIC resolution with no quality loss. The result opens in all modern browsers, image editors, design tools, and any application that supports PNG.

Who This Is For

iPhone and iPad users who need to extract a specific region from a HEIC photo and save it as a universally compatible lossless PNG
Designers and photographers who need a pixel-perfect cropped export from HEIC sources for use in Photoshop, Figma, or Illustrator
Web developers embedding cropped HEIC photos in HTML pages or CSS as PNG images with full browser support
Anyone who needs to crop an iPhone photo and deliver a PNG without installing conversion software
Users preparing HEIC photos for platforms that require PNG — app stores, design systems, or document workflows

Frequently Asked Questions

Is PNG the right format for my workflow?▼

PNG is the best choice when lossless quality is required — product photos for editing, screenshots, UI assets, or any image you plan to edit again later. PNG supports a full alpha transparency channel, making it ideal for graphics with transparent backgrounds. If you need a smaller file and lossy quality is acceptable, HEIC to JPG Crop is an alternative. For modern web delivery, HEIC to WebP Crop or HEIC to AVIF Crop produce smaller files with comparable visual quality.

How precise is the crop tool?▼

The crop operates at native pixel accuracy on the original HEIC dimensions. The canvas is scaled to fit your screen for display, but the actual crop coordinates are mapped back to the full-resolution image before the PNG is generated. You get a PNG at the exact pixel dimensions shown in the crop dimensions badge.

Can I move the crop selection after setting it?▼

Yes — click and drag anywhere inside the crop rectangle (away from the handles) to reposition it anywhere within the image. Handles resize; the interior pans.

What applications can open the output PNG files?▼

All modern browsers, Adobe Photoshop, Figma, Sketch, Affinity Photo, GIMP, Illustrator, and any application that supports PNG — which is virtually all image software. PNG is the most universally compatible lossless image format.

What browsers are supported?▼

All modern browsers — Chrome, Firefox, Edge, Safari (desktop and mobile). The tool uses heic2any as a fallback for browsers without native HEIC support, ensuring HEIC files load correctly everywhere.

Is there a file size limit?▼

There is no server-imposed limit because no upload occurs. The practical limit is your browser's available RAM. Most modern desktops handle HEIC files comfortably. Very large files on memory-constrained mobile devices may be slower to process.
