HEIC to PNG Converter Online — FAQs

Everything you need to know about local, client‑side HEIC→PNG conversion, from lossless quality and optimization to batch limits and device support.

Do you upload or store my images?

No. All processing runs locally in your browser (client‑side WebAssembly). Your files never leave your device. Nothing is transmitted or retained, and once loaded, the tool works offline.

Is PNG output lossless?

Yes—by default we export lossless PNG (24‑bit with sRGB). For smaller sizes, you can enable palette/quantization (PNG‑8 or adaptive) to reduce file size while keeping visual quality high.

When should I choose PNG instead of JPG?

Choose PNG for graphics, UI, text, logos, screenshots, or any image that needs crisp edges, transparency support, or lossless quality. For large photo albums where size matters, JPG is smaller; for transparency and pixel‑perfect detail, PNG is best.

Can I batch convert many HEIC files to PNG?

Yes. Drag‑and‑drop multiple files or folders. We queue and parallelize tasks with auto‑retry. For very large batches, desktop browsers handle memory best.

Can I keep or remove metadata and manage color?

Yes. You can keep or strip EXIF and GPS where present. We embed sRGB profiles for consistent color across apps. Note: PNG stores metadata differently (tEXt/iTXt chunks), and not all viewers display it.

Are there file size or count limits?

No server limits—everything is local. Practical limits depend on your device RAM and browser. The app auto‑chunks big jobs, warns on low memory, and supports pause/resume for stability.
