Why it matters
Why Format Conversion Matters
JPEG for tiny emails
A 4 MB PNG photo becomes 400 KB as JPEG at 90% quality. The difference is invisible — but it's the difference between an email that sends and one that bounces.
Modern web delivery
WebP is 25–35% smaller than equivalent JPEG at the same quality. Converting your assets to WebP before deploying cuts CDN costs and speeds up every page load.
Preserve sharp graphics
Converting a logo or screenshot from JPEG to PNG eliminates compression artifacts and preserves every pixel exactly as intended — critical for UI design assets.

Format guide
Choose the Right Format
Each format has a strength. Pick the one that matches your use case.
PNG
Lossless quality. Every pixel preserved.
FileCrisp compresses PNG metadata. Pixel data is never altered.
JPEG
Smallest files for photos. Invisible quality loss at 80%.
Transparent PNG areas are flattened to white before JPEG encode.
WebP
Best ratio of all three. Smaller than PNG and JPEG.
Supported in all major browsers since 2020.
Converting PNG or WebP (with alpha) to JPEG: transparent areas become white. This is a format limitation — JPEG has no alpha channel. If your image has a transparent background, convert to PNG or WebP instead.
