Format Guide

JPG (JPEG): Best for photos. Lossy compression keeps files small. No transparency. Great for web, social media, email.

PNG: Supports transparency. Lossless compression. Best for logos, icons, screenshots. Larger than JPG.

WebP: Modern format by Google. 25–35% smaller than JPG at equal quality. Supported by all modern browsers.

AVIF: Next-generation image format. Up to 50% smaller than WebP. Supports transparency and wide color gamut. Supported in all modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+).

ICO: Windows icon format used for favicons and application icons. Contains embedded PNG for best quality. Ideal for creating favicon.ico files for websites.

BMP: Windows native format. No compression — very large files. Use only for specific Windows purposes.

GIF: GIF supports both input and output. Input: first frame of animated GIF is extracted. Output: converts to 256-color indexed format — best for simple graphics and icons.

SVG: Vector graphics are rasterized (rendered to pixels) and converted to JPG or PNG.

HEIC / HEIF: iPhone photo format. Converted to JPG or PNG using heic2any library.

TIFF: Professional format used in printing and photography. Lossless quality, large file size. Supports multi-layer and 16-bit color depth.

TGA: Truevision TARGA format used in game development and 3D rendering. Supports 24/32-bit with alpha channel.

QOI: Quite OK Image — lossless format with 20–50× faster encoding than PNG. Lossless quality, smaller than PNG. Ideal for developers.

PPM: Netpbm portable pixmap format. Simple RGB format for Unix/Linux image processing tools and pipelines.

XBM: X BitMap format for X Window System icons/cursors. Outputs as 1-bit black & white C source code.

Frequently Asked Questions

What happens to transparent backgrounds when converting PNG to JPG?

JPG does not support transparency, so transparent areas are filled with white. Use PNG or WebP to preserve transparency.

Is WebP viewable on all devices?

All modern browsers (Chrome, Firefox, Edge, Safari 14+) support WebP. Older iOS 13 or below may not display it.

Can I convert iPhone HEIC photos?

Yes. Upload a HEIC or HEIF file and it will be automatically detected and converted to JPG or PNG.

FAQ

PNG, JPEG, WebP 중 어떤 형식을 써야 하나요?

투명도나 선명한 경계선이 있는 이미지(로고, 스크린샷)에는 PNG를 사용하세요. 사진에는 JPEG, 웹에서 작은 파일 크기가 필요하면 WebP를 사용하세요.

JPEG로 변환하면 투명도가 사라지나요?

네. JPEG는 투명도를 지원하지 않습니다. 투명한 영역은 흰색 배경으로 채워집니다.

이미지가 서버에 업로드되나요?

아니요. 변환은 Canvas API를 사용하여 브라우저에서만 이루어집니다.

변환하면 화질이 떨어지나요?

JPEG 같은 손실 압축 형식으로 변환하면 약간의 화질 저하가 있을 수 있습니다. PNG로 변환하는 것은 무손실입니다.
