Frequently Asked Questions
Which image format should I use?▾
Photos: WebP (best quality/size ratio, supported in all current browsers since 2020) or JPG (universal). Logos / graphics with transparency: WebP or PNG. Modern apps with control over browser support: AVIF (smallest files, but slower to encode and limited Safari support).
Why is WebP smaller than JPG?▾
WebP uses better compression algorithms (predictive coding similar to VP8 video). At equivalent visual quality, WebP photos are typically 25-35% smaller than JPG. The trade-off is older browsers (pre-2020) can't display them — but those are < 1% of traffic now.
Will conversion lose quality?▾
Lossy formats (JPG, WebP-lossy, AVIF) lose some quality each time you re-encode. Lossless formats (PNG, WebP-lossless) preserve every pixel. We use 92% quality by default which is visually indistinguishable from the original for most use cases.
Can I convert PNG with transparency?▾
Yes — PNG, WebP, and AVIF all support transparency. JPG does NOT (transparent pixels become white or black). If you need transparency, use WebP for the best size/quality.
Is my image uploaded anywhere?▾
No. Conversion happens entirely in your browser using the Canvas API. Your images never leave your device — perfect for sensitive or unpublished photos.
