Why Simply Renaming .webp to .png Corrupts Files — And How to Convert Properly
Modern CDNs serve images as .webp to cut bandwidth, but legacy editors, slides, and upload forms still require genuine PNG headers (89 50 4E 47). Renaming the file extension does not transcode the VP8L bitstream.
- Full Alpha Transparency Preserved: Pre-locked to lossless
image/pngoutput so UI icons, stickers, and logos retain crisp transparent edges. - Zero-Upload Bulk ZIP Export: Convert 50+ WebP assets simultaneously in browser RAM and download a single clean PKZip archive.
Frequently Asked Questions (FAQ)
Q1 Does converting WebP to PNG preserve transparent backgrounds?
Yes. Because this preset defaults to lossless 32-bit RGBA PNG encoding, every pixel’s alpha channel is preserved with zero background matte.
Q2 Is there a 5-file or 10MB limit like CloudConvert or TinyPNG?
No limits at all. Everything runs on your own CPU/GPU inside browser memory via Rust WebAssembly, so we pay $0 in server bandwidth and never throttle batch sizes.
