무료 온라인 이미지 형식 변환기
데스크톱 소프트웨어 없이 이미지 형식을 전환합니다. PNG, JPEG, WebP, GIF, BMP, AVIF, TIFF 또는 ICO을 업로드하고 PNG, JPEG, WebP 또는 AVIF(브라우저가 AVIF 내보내기를 지원할 경우)로 다운로드합니다.
슬라이더를 사용하여 JPEG/WebP/AVIF 품질을 조정하세요. 모든 것이 브라우저에서 로컬로 실행됩니다. 파일은 Dokall 서버에 업로드되지 않습니다.
Frequently Asked Questions
Which formats can I convert between?
Input: PNG, JPEG, WebP, GIF, BMP, AVIF, TIFF, ICO. Output: PNG, JPEG, WebP, and AVIF (when your browser supports AVIF encoding). Not all input formats support all output formats.
Does conversion reduce image quality?
PNG and WebP lossless modes preserve quality. JPEG, WebP lossy, and AVIF use compression that may reduce quality. Adjust the quality slider to balance file size and visual fidelity.
Can I convert multiple images at once?
Upload and convert images one at a time. For batch conversion of many files, dedicated desktop tools or command-line utilities like ImageMagick are more efficient.
Is my image uploaded to a server?
No. Conversion uses the browser Canvas API. Images are processed locally and never sent to Dokall servers.
Why is AVIF output not available?
AVIF encoding depends on browser support. Chrome and Firefox support AVIF export in recent versions. Safari added support in later releases. If AVIF is unavailable, use WebP as a modern alternative with wide support.
