Format Selection Guide
Document Formats: PDF suitable for formal documents with consistent cross-platform display. DOCX suitable for editable documents. Markdown suitable for technical docs and blog articles.
Image Formats: JPG suitable for photos with high compression but no transparency. PNG supports transparency, ideal for icons and UI elements. WebP is modern format with high compression and transparency, ideal for web use. SVG is vector format suitable for icons and logos with lossless scaling.
Video Formats: MP4 has best compatibility for web and mobile devices. WebM is open format suitable for HTML5 video. GIF suitable for short looping animations but large file size and limited quality.
Audio Formats: MP3 has best compatibility. AAC has better quality than MP3, prioritized by iOS devices. FLAC is lossless compression for high-quality audio requirements. OGG suitable for web audio but less device support.
Application Scenarios
Convert PDF to editable Word documents or Word documents to PDF to lock format. Convert PNG to WebP to reduce webpage load size, or convert HEIC format to JPG. Convert videos to different device or platform-supported formats. Convert Excel sheets to CSV for data import. Convert EPUB to MOBI for Kindle reading.
Important Notes
Single file maximum supported is 100MB. Extra-large files recommended for dedicated desktop conversion tools. Conversion quality depends on source file quality and target format characteristics; lossy format conversions will lose some data, recommend keeping original files.
Different format conversions consume different credit amounts; complex conversions typically consume more credits. Conversion time depends on file size and format complexity; videos and large files may take longer.
Uploaded files transmit to CloudConvert servers for processing. While service deletes files after conversion, still recommend not uploading files with sensitive information. Some special or encrypted formats may not convert; complex document conversions may lose certain format features.
Common Issues
Converted file has garbled text or format errors? May be that source file contains special fonts or complex layouts; recommend using professional software for conversion or simplifying source file format.
Why isn't my needed target format available? Some format combinations don't support direct conversion; try converting to intermediate format first, then to target format.
Some files fail during batch conversion? Each file's conversion result displays independently; successful files can download normally while failed files show specific error information.
