What you bring, what you leave with.

HEIC

HEIC is Apple's iPhone photo format. Browser decode support is limited; for best results, convert HEIC on a Mac before uploading.

Target.ico

ICO

ICO is the Windows favicon format. Pixelmint wraps a PNG inside a single-frame ICO container — ideal for browser tabs and desktop shortcuts.

Q.01How do I convert HEIC to ICO?+
A.01

Drop your HEIC file onto the converter above (or click to pick one), then hit Convert. Your ICO download starts the moment the encoder finishes — usually under a second. Nothing leaves your device.

Q.02Is converting HEIC to ICO lossless?+
A.02

No. ICO uses lossy compression by default. You can tune the quality slider to trade file size for fidelity. Quality 90 is a good default that beats most online tools.

Q.03Will my HEIC files be uploaded to a server?+
A.03

No. Pixelmint runs the entire conversion in your browser using the Canvas API. Your image bytes never touch our servers, which is why this is safe for confidential screenshots, IDs, and proprietary artwork.

Q.04Is there a file size limit?+
A.04

There's no hard limit, but very large images (over ~50 megapixels) can be slow on low-RAM devices because everything happens locally. Most browsers cap canvas size around 32,767 pixels per side.

Q.05Does it cost anything?+
A.05

No. HEIC to ICO conversion is free, unlimited, and has no watermarks, signups, ads on the file, or hidden tiers.

Q.06Why does HEIC sometimes fail?+
A.06

HEIC support depends on your browser. Safari on macOS / iOS decodes HEIC natively. On Chrome, Edge and Firefox, decode often fails — convert the file to JPG on your phone first, or use Safari.
