Eight guides built around decisions and evidence
These guides explain only workflows supported by RAON Tools. They combine calculated size estimates, code-level processing checks, practical checklists, and limitations that can change a result. Each guide names its reviewer and latest review date.
Audio decisions and real workflows
MP3 bitrate and size
Compare 64-320 kbps with one-minute, ten-minute, and one-hour file-size estimates.
Use the bitrate tableMusic practice audio
Prepare lesson notes, instrument demonstrations, backing tracks, and rehearsal files without losing the source.
Follow the practice workflowAudio upload failures
Separate extension, codec, size, destination, browser, and memory errors before converting again.
Diagnose an audio fileImage decisions and output checks
Compression vs resize
See how compression, resizing, and cropping differ, with pixel-count and browser-memory examples.
Choose the right image actionJPG, PNG, WebP, and HEIC
Protect transparency, orientation, metadata needs, and compatibility when changing image formats.
Choose an image formatHow the browser workflow behaves
Browser processing and privacy
Learn where the selected media is processed, which network requests still happen, and what local processing cannot guarantee.
Read the technical noteBatch conversion checklist
Process up to ten files sequentially, control memory pressure, verify outliers, and use ZIP downloads appropriately.
Use the batch checklistEditorial standard
RAON Tools does not publish a separate short page for every keyword. Closely related questions are combined into these maintained guides. Calculated values are labeled as estimates, observed application behavior is dated, and format or browser limitations are included alongside recommendations.
Corrections are welcome at sundaymusic@kakao.com. Please include the page, browser, and specific sentence or behavior. Do not send private source files.

RAON 가이드는 검색어마다 짧은 글을 따로 만들지 않고 관련 내용을 8개의 핵심 가이드로 통합했습니다. MP3 용량 계산표, 이미지 픽셀·메모리 예시, 브라우저 처리 코드 확인, 업로드 오류 진단표와 실제 연습 음원 작업 흐름을 포함합니다.
각 글에는 작성 주체와 검토일을 표시하며, 계산값과 실제 확인한 동작을 구분합니다. 잘못된 설명이나 다른 동작을 발견하면 파일을 첨부하기 전에 브라우저와 오류 내용을 이메일로 알려주세요.
