Compress vs Convert: What to Do When a File Is Too Large
Changing format and compressing are different levers. Use conversion for compatibility; use compression for size — sometimes you need both.
Convert when the destination rejects the format
HEIC that won’t upload, MOV that won’t play on Windows, or WebM that won’t open on iPhone are compatibility problems. Convert to JPG/MP4 first — remuxing alone may not shrink bytes.
Compress when the format is fine but the size isn’t
A valid MP4 or PDF can still exceed chat or LMS limits. Use a compressor (or lower bitrate/quality) after you have a compatible format. Zipping a JPG rarely helps much.
Common workflow
Master → convert for compatibility → compress once for delivery → keep the master. Avoid download→recompress loops that stack generation loss.
