HEIC から PNG への変換について
PNG is a uncompressed, lossless raster graphics format widely supported across graphics editors, web browsers, and publishing tools. Converting HEIC to PNG ensures maximum image fidelity and preserves clean edges, ideal for design work and high-quality printing.
よくある質問
When should I use PNG instead of JPG?
Use PNG when you need lossless quality or full graphic fidelity — for example, for graphics, screenshots, logos, or images you'll edit further in Photoshop or Canva.
Is my photo uploaded to a server?
No. Conversion happens locally in your browser using WebAssembly. Your file never leaves your device.
Are there any file size limits?
Because conversion runs in your own computer's memory, file size limits are governed only by your device hardware.
